The BD 01 system is quickly to install and ideally suited for use in workshops and trade premises, as here, at a photo-grapher’s.

In the petrochemical industry, it is the PEC system that provides reliable and fault-free power supply.

The ideal system for production lines needing a great deal of power is theLD system up to 5000 A.

SIVACON 8PS -

Busbar Trunking Systems in Action

Busbar trunking systems in the low-voltge range perform the safe and reliable transmission and distribution of electrical power from transformer via main distribution board and sub-distribution board right to the load. Siemens busbar trunking systems are the complete and efficient answerin this area:• The CD system for 25 A to 40 A• The BD01 system for 40 A to 160 A• The BD2 system for 160 A to 1250 A• The PEC system for 800 A to 6000 A• The LD system for 1100 A to 5000 A• The LX system for 800 A to 6300 A

All these systems are ’Type-tested LV switchge-ar assemblies’ (TTA) to IEC 60439-1 and -2. This ensures that they offer a standard of safety and reliability that meets the particularly high perfor-mance expectations of automated production and for building services provision.

Performance characteristics:• Clear network structure• Unproblematic retrofitting in the event of load

changes• Low operating costs due to uninterrupted ser-

viceability• Simple planning and installation

Room-covering systems for lighting installa-

tions and small loads

The CD system (up to 40 A) allows you to supply lighting installations covering the whole expan-se of, say, furniture showrooms, supermarkets or greenhouses with power, and also provides the means to easily fix them in position.Due to its pleasing appearance, the equipment is well suited for use in sales rooms visited by the public. On the other hand, its high degree of protection, to IP54, allows the CD system to be used even in harsh environments.

The power source for loads with no fixed

location

The BD01 system is ideally suited for the power supply (up to 160 A) in workshops and trade premises. The trunking units are easily and quickly to put together. The anti-rotation feature on the tap-off units makes sure that the units are correctly fitted and allows for easy retrofitting even while the production is running.Other benefits: minimum stock holding and un-complicated planning due to one standard frame size for five different current ratings.

1/9

Universal power distribution

The BD2 system (up to 1250 A) can supply power to medium-size loads in buildings and in all industrial applications. Prefabricated tap-off units fitted with many differing component combinations make this equipment universally applicable. Two standard frame sizes covering all current ratings simplify stock keeping and planning.

Safe and reliable power transmission in the

petrochemical industry

The PEC resin-insulated system, up to 6000 A, has a high degree of insulation protection andthus an enormous resistance to external interfe-rence factors. This ensures safe and reliable transport of power even in rough weather or in highly dust and dirt and corrosion polluted industrial environments. Typical applications of this system is the petrochemical industry, waste incinerators and power stations.

High system serviceability in production

The louvred LD busbar trunking system, up to 5000 A, is the system for transporting current in production lines with a large energy require-ment, such as in the automotive industry. A separate PE busbar ensures that the protective device in such a system responds reliably even if the current paths are relatively long. The high short-circuit rating allows medium-voltage switches to be used as protective elements for the transmission of power between transformer and main circuit-breaker. Tap-off units up to 1250 A available as standard.

Flexible power distribution in multi-storey

buildings

The LX sandwich-style system, up to 6300 A, is used where large quantities of power need to be transported, uninfluenced by the mounting posi-tion of the system.Conductor configurations with the PE conductor insulated along its entire length, and a double-size neutral can ensure the interference-free dis-tribution of power in places such as radio stations, computer centres or at internet providers’. The system is protected to IP54 as standard, and tap-off units up to 1250 A are available as standard.

Siemens offers modular component cabinets for indication, control and monitoring of the flow of power through busbar trunking systems. These cabinets are equipped with bus interfaces, control circuit devices and power meters.

The LX busbar trunking system is the perfect equipment for multi-storey buildings where large quantities of power need to be transpor-ted, uninfluenced by the mounting position of the system.

Overview

Developing a power distribution concept, including system and component configurations, involves finding an effective solution based on customer requirements and supplier technology. This design information brochure for the LX busbar trunking system for rated currents ranging from 800 A to 6300 A, is designed to help with this task.

Descriptions of the different systems, their technical features and areas of application are provided, as well as drawings of the individual busbar trunking system elements. Details vital for planning are emphasized and explained.

The section entitled, “LV 72.T 2004 - Further Information” sug-gests approaches for creating effective planning solutions. Indi-vidual engineering principles are introduced and detailed infor-mation on subjects such as fire barriers and functional endurance is provided.

Siemens offers services and engineering tools for preparing ten-der specifications. An overview and explanation of functions and features is also included in this section.

General

Creating a design concept for a power supply system, not only involves observing applicable standards and regulations, but also examining and clarifying economic and technical require-ments. Electrical equipment, such as distribution boards and transformers, should be selected on the basis of their suitability in terms of the overall system – not just in terms of their individual features.

Components should not only be appropriate for rated operation, but should also be suitably dimensioned to withstand fault situa-tions. A power distribution concept should also take the follow-ing points into consideration:• Building type, use and form (for example, high-rise building,

flat buildings and number of floors)• Load centers and possible supply paths and locations for

transformers and main distribution boards• Building-dependent ratings based on maximum demands per

unit area depending on what the building is used for• Regulations and guidelines of building authorities• Power supply company guidelines.

There will always be more than one possible solution which will have to be assessed in terms of its technical and economic advantages and disadvantages. In making this assessment, the following requirements should be a priority:• Simple and transparent design• Long service life• High availability• Low fire load• Flexible adaptation to building modifications.

These requirements are generally easy to meet with appropriate busbar trunking systems. For this reason, engineers increasingly favour busbar trunking systems over cable installations for power transmission and distribution applications. Siemens of-fers busbar trunking systems for rated currents ranging from 25 to 6300 A:• The CD busbar trunking system from 25 to 40 A is ideal for sup-

plying lights and small consumers• The BD01 busbar trunking system from 40 to 160 A is de-

signed for supplying workshops with tap-offs up to 63 A• The BD2 busbar trunking systems from 160 to 1250 A is de-

signed for supplying medium-sized consumers in buildings and in industry

• The ventilated LD busbar trunking system is designed for sup-plying consumers with a high power consumption in industrial applications

• The LX sandwich system is designed for supplying large power requirements in buildings

The design information brochure LV 71.T is available for design-ing the BD2 and LD busbar trunking systems.

Benefits

The complexity of today‘s buildings makes power distribution with a high level of transparency and flexibility an indispensable requirement. The uninterrupted provision of power is also abso-lutely essential for production plants with multiple shifts.

Busbar trunking systems meet these demands for an economi-cal power distribution system with simple design, fast installa-tion, optimum flexibility and safety by offering: • Straightforward network structures• Minimum space requirements• Easy retrofitting with sudden changes in location and con-

sumer ratings• High short-circuit rating and low fire load

The LX busbar trunking system is a type-tested low-voltage as-sembly (TTA) in accordance with IEC/EN 60439-1 and 2 in the form of an aluminium enclosed sandwich system. The LX sand-wich system consists of busbars, insulation, the aluminium en-closure and the fastening and connection elements.

LX trunking unit with joint block

Application

Purpose and types of busbar trunking system

Various busbar trunking system components are responsible for transporting power between transformers and low-voltage power distribution systems. They are used between the trans-former and main distribution board and then on to the subdistri-bution level.Trunking units without tap-off points, available in standard lengths, are used for transporting power. In addition to the stan-dard lengths, customers can select lengths from several ranges to meet their particular building requirements.

Power distribution

The main application of busbar trunking systems is power distri-bution. The advantage of such systems over cable installations is that the locations of power tap-off points are not permanent, but can be moved to any position within the entire system. To tap power at any given point simply requires positioning a tap-off unit at that location on the busbar.The result is a flexible distribution system for decentralized power supply to a particular line or area. Tap-off points can be mounted on one or both sides of straight trunking units.The LX busbar trunking system provides tap-off units from 80 A to 1250 A for power tap-offs and for connecting consumers, pro-viding the power supply for consumers in the range between 10 kW and over 400 kW. Tap-off units can be fitted with either fuse switches or circuit-breakers.

Tap-off units for flexible power tapping

With all busbar trunking systems, pluggable tap-off units have a high safty standard, the following requirements will be fulfilled by all tap-off units:• Early-make PE contact for mounting and late-break contact for

removing• No live part can be accessed (degree of protection IP2X) dur-

ing mounting, unmounting or connection.• Mounting should only be possible in the correct phase se-

quence.The plug-in LX tap-off units up to 630 A meet these require-ments.The LX tap-off units from 800 A to 1250 A are fitted permanentlyto the connection points of the trunking units and cannot be fit-ted/removed while the system is live. Installation is only permis-sible when the system is isolated.

Application

Building applications

LXA/LXC and LDA/LDC systems are available for distributing large power requirements in buildings. For this type of applica-tion busbar trunking systems frequently have to meet the follow-ing requirements:• Flexible power distribution in high-rise buildings • Safe power supply for electronic consumers

To meet these requirements the LXA/LXC systems have very favourable features in terms of design, high load capacity of theneutral conductor as well as an additional isolated PE conductor.

Nevertheless, there are applications for which the use of the LDA/LDC system is recommended. LD systems are ideally used in applications with primarily horizontal busbar runs and re-quired protection to IP34.

Industrial applications

When used in industrial applications, busbar trunking systems have to meet a high level of requirements in terms of short-circuit ratings. In power supply systems for manufacturing plants with a high power requirement, such as with welding robots in weld-ing lines, very high short-circuit currents can occur that require the use of very robust consumer tap-offs. The LDA/LDC systems are ideal busbar trunking systems for typical industrial applica-tions. LXA/LXC systems may, however, also be useful in particu-lar industrial applications such as in operating areas exposed to fire hazards. In this kind of application protection to IP5x is re-quired, where there is a risk of fire due to inflammable dust.

Conductor configurations

IEC 364 stipulates that electrical equipment must be selected according to the type of system at hand in order to determine the protective measures required. For the LX system this selection is based on the appropriate conductor configuration.

N and PE conductor cross-sections/Clean Earth

Neutral conductor cross-section

The rise in new electronic consumers that are sensitive to inter-ference, particularly near the power supply in the building, is presenting busbar trunking systems with new challenges. Inter-ference from electromagnetic fields and harmonics in the mains supply impair the correct functioning of computers, servers and many other state-of-the-art electronic devices. Particularly, the large number of AC consumers in a mains supply place a high load on the neutral conductor on account of the resulting har-monics. Double neutral conductor cross-sections (200 %) re-duce the susceptibility of the system in networks subject to har-monics.

PE conductor cross-section

A large PE conductor cross-section also provides optimum safety for the power supply since the reduced loop impedance ensures rapid interruption of short-circuit currents. This conse-quently reduces the risk of possible downtimes thanks to the rapid disconnection of upstream protective devices.

Clean Earth

Insulated PE conductors offer optimum reliability and safety in the power supply of electronic consumers in buildings on ac-count of their complete insulation from the busbar enclosure. In the event of a short-circuit between the phase and the consumer enclosure this PE conductor (Clean Earth) is not affected by this fault and is therefore potential-free during a short-circuit to an ex-posed conductive part. Even leakage currents in the enclosure due to magnetic fields do not affect the Clean Earth. The Clean Earth is therefore ideal as the PE connection for susceptible electronic loads.

Tap-off units

1) The rated current depends on the mounting position of the circuit-breaker. If the tap-off unit is suspended (power tap-off below) a rated current reduc-tion to 0.9 x Ie must be allowed for.

2) Cable entry requires use of cable glands with strain relief (not included in scopeof delivery).

3) The values are valid for tap-off units with NZM7 and NZM10. Tap-off units with 3VL on request.

Overview

Project handling

Engineering is performed in six stages:

Determine and check building dimensions• Procure floor plans to scale.• Check drawing dimensions on site.• Record dimensions on site if no floor plans are available.• Convert them into binding documentation.• Immediately after receipt of order, make the order reservation

in the production factory.

Decide on and draw busbar runs• Draw a scale plan view of the busbar layout on the floor plans.

Co-ordinate the busbar runs with other equipment installations. Take minimum clearances into consideration.

• Transfer the dimensions decided on to an isometric represen-tation.

• Ensure that the tap-off points are useful and accessible.Note the minimum clearances to the jointing points between trunking units when the respective tap-off units are fitted.

• Take busbar runs and building expansion into consideration when engineering expansion compensation. External influ-ences resulting from building expansions can be compen-sated with expansion compensation.

• When engineering the horizontal busbar runs, pay attention to the PE(N) position for vertical mounting.

Define interfaces and links• Definition of interfaces

- To be held and documented with the customer about techni-cal requirements and physical configurations, floor plans etc.

- To be held with other equipment installers (heating, ventila-tion, sanitation, transformer suppliers) with regard to dimen-sioning, lug spacings and precise locations.

- To be held with distribution board suppliers/builders: provide connection units for non-Siemens distribution boards in good time.

- Obtain information about fire protection segregated areas.

Engineer the angle and branch points/units• Engineer complex direction changes first:

- If necessary, produce a section drawing.- Customized solutions (non-standard solutions ) require im-

mediate consultation with the factory.Special solutions have longer lead times and are more expen-sive than standard units, since the cost involved in clarifica-tion, ordering and manufacturing is higher.

• Engineer simple direction changes:- For simple horizontal/vertical direction changes use standard

types with standard lengths.- Preferably engineer optional lengths using straight trunking

units.

Use straight lengths to complete the run• Fill the sections between the angle and branch units using

standard lengths.• Only then should the custom lengths be determined. Custom

lengths should be kept to an absolute minimum to avoid longer lead times.

Note:Only straight lengths are custom lengths. The fewer the number of custom lengths used, the shorter the lead time.Order custom lengths immediately as construction progresses.

Producing a parts list

Sequence to be followed:• Enter the dimensions of the feeder units, straight trunking units,

angle and branch units, and tap-off points etc. for the run.• Define types• Create parts lists

Order processing

• If appropriate, agree staged deliveries for large orders.• Always mark parts with the Drawing Item No., in order to ensure

identification at the installation site.• When drawing up the orders

- Match delivery dates to the construction phases/to construc-tion progress.

- Ensure delivery for installation at different points on the con-struction site by structured busbar run designation or stag-gered ordering.

Customer-specific non-standard solutions (on request)• Immediately after the order has been placed, request the or-

dering data from the technical department responsible.

Note:Customized solutions always have longer lead times.

Optional lengths• After determining exact dimensions place order in a separate

order.

Order documents (send to factory)• Binding order• Parts list • Engineering drawings.

Conductor material

The conductor materials used in LX systems are aluminium for(LXA) and copper for (LXC).Busbar trunking systems with aluminium conductors are prefer-able due to their lower weight and lower costs.

LX busbar systems with conductors made from aluminium

a Aluminium busbars Tin-on-nickel platedd Insulation with high thermal stability

LX busbar systems with conductors made from copper

a Copper busbars Tin platedd Insulation with high thermal stability

Mounting position, degree of protection and rated current

The rated current of the busbars is independent of the mounting position of the busbar with the following exceptions. That means: no derating of the current is necessary.

Exceptions:LXA07..: Rated current 2300 A

with busbar position horizontal, flatLXA09..: Rated current 3800 A

with busbar position horizontal, flatLXC01..: Rated current 900 A

with busbar position horizontal, flat

The busbar system has IP54 degree of protection as standard. Enhancement of the degree of protection by fitting additional components on site is only possible for power transmission (on request).

Sizes, single systems and double systems

The size depends on the current rating and the conductor mate-rial. A total of 10 sizes are available. 7 sizes are single systems and 3 sizes are double systems. The single system consists of an enclosure each with 3 to 6 aluminium or copper busbars. The double systems feature 6 to 12 busbars each in two enclosures. The exact numbers of busbars depends on the required con-ductor configuration. There are eight different types of conductor configurations.

Connection

The connection is established by one or two joint blocks. One or more fixing screws are simply tightened by using a standard screw or ring spanner. Secure fixing is established in the short-est possible time in this way.

In individual steps: The first screw head shears off as soon as the defined torque is attained. Below this, a second screw head is located which actually releases the clamp connection. When re-using the trunking unit (joint block), it must be retightened to the defined torque of 120 ± 10 Nm.

The joint block is fixed to the trunking unit. It does not compen-sate for longitudinal expansion of the trunking unit. The expan-sion unit must therefore be engineered in accordance with the applicable engineering rules, see „Expansion unit and fixed point“.

Type definition

General information

An engineering type reference consists of the system size LX...... - and a trunking unit type. The system size is determined by the LX type reference key. The trunking unit type depends on the busbar run routing or the tap-off points. In order to simplify the engineering, the representation of the trunking units has been reduced to essential features by the use of symbols.

The critical factors for type definition are:• Mounting position of the busbars within the trunking unit• Phase sequence, location of L3, PEN, N or PE conductor• Position of the joint block• Nature of the busbar run• Actuating side of the joint block


Basic information points

a Fixing screw for joint block: to be always on the L1 side

s Mark busbar end with joint block by:•d The position of L3, PEN, N or PE conductor is marked by a solid thick line

on the unit. The end without the joint block is always on the right.f Mark open busbar end (without joint block) with – and position busbars

edgewiseThe view is always the end of the trunking unit without joint block.

Direction change to: V = the frontH= the rearR = the rightL = the left

Tap-off points

Tap-off points are only possible on straight trunking units. The type is determined by stating the length of the trunking unit (standard or custom length). The position of tap-off points is predefined on standard lengths. With custom lengths it is possible to define the tap-off points within defined limits (see Chapter „LXA/LXC Busbar Trunking System“ – Selection and ordering data).

The position of tap-off points at the top is variable by rotating the trunking unit around the indicated axis (see Chapter „LXA/LXC Busbar Trunking System“ – Selection and ordering data).

Important points for the viewing direction:• Busbar position: edgewise• View from the trunking unit end without a joint block• Location of the thick continuous line on the right• The busbar run points away from the viewer.

Examples of type definition

Note:Tap-off units may not be fitted in the joint block (flange cover) connection area. The usability of the tap-off point therefore de-pends on the position and the dimensions of the tap-off point sel-ected.Details of all selectable dimensions in m. Note a change in position of the tap-off points when the trunking unit is rotated.

To determine the type, the angle and branch units must be viewed as follows:• Busbar position: edgewise• View from the busbar end without a clamping terminal• PEN(N) position on the right• The busbar run points away from the viewer.• Four basic directions

Four basic directions

Direction change to:V = the front (top)H= the rear (bottom)R = the rightL = the left

Limb designations

The limbs of angle and branch units have a fixed designation:Limb without joint block fitted = X limbLimb with joint block fitted = Y limbLimb in between (where present) = Z limb.

Examples of type definition

For simple changes in direction, the type designation is gov-erned by the direction of the Y limb.

e.g. elbow, rightLXA(C)..... -LR

Direction change to the right Elbow or knee

The type designation of offset changes of direction is governed by

- the direction of the Y limb and - the position of the offset

of the type.

e.g. offset change of directionLXA(C)....-LLV

For Z units, the type is governed by the direction of the Z limb:

Minimum wall clearance horizontal busbar runs

The minimum wall clearance Wmin depends on:• The position of the screw for tightening the joint block.

The minimum space requirement is 0.10 m.• The dimensions of the tap-off unit chosen for power

distribution.

Minimum ceiling clearance

The minimum ceiling clearance Dmin depends on:• The dimensions of the tap-off unit chosen for power distribu-

tion. It must be possible to open the cover of the tap-off unit. It must be possible to remove/install the tap-off units.

• System ventilation. The minimum clearance of 0.10 m must be maintained in order to ensure sufficient heat dissipation.

Note:Where fire barriers or expansion units are used, the clearance from wall/ceiling at such points is reduced, as for example by the system covering parts of the fire barrier.

Universal connection units

4

Application

LX universal connection units are used as feeder units for trans-formers and for distribution board connection (with type suffix +LD-FLP). A connection with the LX system can be established via any of the trunking units or junction units listed in the cata-logue.

Design

The universal connection unit is supplied fitted• with connection lugs

in fixed positions as specified by the customer• with a connection suitable for any of the trunking units or angle

and branch units listed in the catalogue (without joint block).

When engineering the phase sequence and lug spacing, it is im-portant to note the direction of viewing:• Mounting position of the busbars within the trunking unit

edgewise• Determine the phase sequence of the remaining busbar run,

i.e. position the PEN or N conductor on the right or left depen-ding on the conductor configuration (see marking in bold).

Phase sequence and lug spacing

Three different types are available for engineering:

Type 1: LX...-AS1

Overview

Versions

The non-Siemens distribution board connection units feature copper conductors. They are supplied without joint blocks. Refer to the selection and ordering data for type references.

Connection options

Since these units are used for customized solutions, early agree-ment with the distribution board manufacturer is necessary.Whoever designs and installs the connections between the dis-tribution board connection unit (Siemens product) and the distri-bution busbars of the non-Siemens distribution board, as a rule the distribution board manufacturer, is responsible for this work.

Rated currents

The rated currents can be taken from the key to type references in the selection pages. These specifications conform toIEC/EN 60 439-1 and -2 for an ambient temperature of 35 °C on a 24 h mean. The limit temperature of the copper busbars insu-lated with a highly thermally stable material is 135 °C. When using non-Siemens connection units in distribution board installations, it is necessary to ensure that the temperature limit is not exceeded.

Terminal capacity for the copper connections see Chapter „LXA/LXC Busbar Truncking System“ – Dimension drawings.


The short-circuit rating of connections to non-Siemens distribu-tion boards is governed by the copper connections in the distri-bution board installation. Only the manufacturer of the distribu-tion board installation can provide verification of the short-circuit rating of the dropper bars.The unit for connection to non-Siemens distribution boards is supplied as a type-tested unit.The rating of the copper connections must be matched to the re-quired short-circuit level.

Connection to the SIVACON system

Version

The connection to the SIVACON system is implemented via a distribution board entry flange.This is screwed onto the standard cut-out in the top/bottom plate in the SIVACON and provides the respective entry opening for the assigned busbar system.

Connection options

The standard trunking unit is connected directly to the distribu-tion board connection via a joint block. Assignment of the LX systems to distribution board connection see SIVACON produc-tion selection catalogue.

Overview

Connection possibilities

A LX connection to the distribution board is possible from above. The SIVACON 8PV, 8PT connection system is entirely inside the distribution board.

Connection is carried out by means of standard trunking units, straight trunking units, angle and branch units or T units. The ter-minal clamp of the trunking unit is connected directly to the con-nection unit inside the distribution board.

The distribution board entry flange is included in the scope of supply.

Rated currents

During engineering it has to be taken into account that the rated currents of the distribution boards are not necessarily the same as the ones of the busbar system selected.

Fixed point

Dimensions b and d exactly determine the centre of the busbarsystem above the distribution board. With this dimension as a fixed point, engineering of the trunking unit can be carried out.

Expansion unit and fixed point

4

Overview

The busbar pack and enclosure expand due to the heat losses arising when the busbars are under load.

The lengthwise expansion of the busbar pack depends on:• The conductor material used in the busbar systems• The mode of installation of the busbar run

(horizontal or vertical)• Whether used for power transmission or distribution.

Engineering must take into account three different situations:• Engineering of horizontal busbar runs• Engineering of adjustments in height within horizontal runs• Engineering of vertical busbar runs

Expansion unit

Compensation for expansion is implemented by using a special trunking unit with built-in expanding bands. This unit is able to compensate for the expansion of the busbar run up to the defi-ned maximum run length and must be engineered for horizontal or vertical busbar runs according to the engineering guidelines.

Within a defined range, the expansion unit can compensate for tensile as well as compression forces.

Fixed point

Fixed points are special fixing brackets which are used together with fixing material provided on site to rigidly secure the trunking unit. They guarantee compensation for expansion in a defineddirection.

A distinction is made between fixed points for horizontal and ver-tical installations (see „Selection and ordering data“).

A fixed point must be attached to the following busbar compon-ents:• Universal connection units (AS and AS-T)• Cable connection units (KE)• Connection units for non-Siemens distribution boards (FA).• Depending on busbar run and lengths, also straight trunking

units and angle/branch units

Engineering for horizontal busbar runs

General procedure

Note the following for busbar runs:• Determine the busbar elements: feeder units, angle and

branch units, end flange• Determine the run lengths between busbar elements• Provide feeder units with fixed points• Use fixed points to divide up large busbar runs into partial bus-

bar runs• Place the expansion unit centrally between two fixed points

Vertical busbar runs

General procedure

Note the following for busbar runs:• Determine the busbar elements: feeder units, angle and

branch units and end flange• Determine the run lengths between feeder units, angle/branch

units and end flange• Provide feeder units with fixed points• Use fixed points to divide up busbar runs into partial busbar

runs• Engineer expansion compensation• Engineer fixing bracket for each floor

Max. admissible length of L1 part runs

After the feeder units, angle and branch units and end flange are specified within a run, the following runs can be created:• Run between two angle and branch units• Busbar run between an angle and branch unit and end flange• Busbar run between feeder unit and angle and branch unit• Busbar run between feeder unit and end flange

This is then subdivided into maximum permissible partial run lengths L1.

The partial run length L1 depends on the conductor material of the trunking system as well as its use (power transmission or po-wer distribution):

1) At least one tap-off unit per floor

These partial run lengths are located• between two fixed points with one expansion unit• between fixed points and end flange without expansion com-

pensation

For partial run lengths between feeder unit and fixed point with an expansion compensation, the partial length L1 is halved.

Fixing

The busbar run is secured using special fixing brackets (LX-BH, LX..-BF or LX-K) that allow for a certain amount of slippage of the busbar run when it is expanding under load.Details about fixing intervals are to be found in Chapter„LXA/LXC Busbar Trunking System“ – Technical Data. Each trun-king unit must be supported by at least one fixing bracket.

Mounting position

Due to the limited permissible mounting position of the overload and short-circuit protective devices in the tap-off unit and the easy mounting of the trunking units, the mounting position for the vertical installation of busbar runs is fixed

a Compensate for uneven walls using material provided on site.The specified minimum clearance for the vertical fixing bracket is 10 cm.

s Here: centre fire barrier = centre fire ceiling.(tolerance range for positioning see page 4/16 „Fire barrier“)

g PEN (L3, N or PE)1) always on the righth The trunking unit end without joint block is always positioned at the bottom.

The joint block should always be tightened at the end with phase L1.1) The PEN, L3, N or PE conductor is on the right depending on the conduc-

tor configuration.

Fixing bracket and fixed point

The fixing bracket for vertical installation is designed for taking the weight of the busbar run for a floor height of h = 3.40 m to 3.90 m. Consequently the type designation of the bracket must include the complete type reference key and the use of tap-off points.

At a floor height of h = 3.40 m to 3.90 m the fixing bracket should have the following dimensions:

1) At least one tap-off unit per floor

The type designation of the fixed point depends on whether sin-gle systems or double systems are mounted:

Engineering example

Details required• Number and height of the floors• Ratings per floor and types of load• Utilization and rated load factors• Feed transformers (characteristic data, position)• Special requirements (degree of protection, fire barrier etc.)• Required number and positioning of tap-off points.

Given• 11 floors each with 8 residential units• Rating of 38 kW per residential unit• Ue = 400 V, p. f. = 0,8, 5-conductor system,

degree of protection IP54• Rated load/utilization factor:

α = 0,7 / β = 0,45• Incoming supply from non-Siemens distribution board via LX

connection unit• Transformer rating = 1600 kVA• Details and construction plans required for engineering the

trunking layout• Tap-off units to be positioned at eye level.

Rated current

The rated current per floor is calculated using the following for-mula. The formula also allows the rated current for the tap-off units to be defined.

INB = Rated current per floor [A]Ue = Rated operational voltage [V]cos ϕ = Power factorPinst = Total installed power per floor [kW]α1) = Rated load factor

The rated current per busbar run is calculated from:

IB = Rated currentβ2) = Utilization factor for the total number of loads

1) If α is not stated, the values from the “Number of main circuits” table can be used. If the power factor is not stated, it may assumed to be = 1 for purely residential high-rise buildings.

2) The local utility companies have good empirical values for utilization fac-tors; they differ from region to region. The “Type of load” table provides good average values.

Engineering example

The current rating of the system is unaffected by the installation orientation, i.e., 2000 A can be conducted in the horizontal and vertical orientations without derating. The degree of protection is IP54. The system to be selected is thus: LXA0651.

Once the system has been selected, the following documents are produced for the order:• Installation plan on FO 10 (PU-AU-LD) or using the LX- engi-

neering tool• Parts list FO 82 (STL) or automatic generation using the LX

engineering tool• Binding order• All documentation is to be sent to the factory.

Unless the application necessitates a change, the rated load factor from IEC/EN 60439 (DIN VDE 0660 Teil 500) α may be used for.

Notes

The current rating is unaffected by the mounting position (hori-zontal or vertical). The standard degree of protection is IP54. The floor height is 3.40 m.

Since this is a single-trunking system, one fixing bracket is to be fitted for a vertical installation.

The expansion compensation must be engineered for the begin-ning of the busbar run. It must be attached to the lower end.

(For further details: see page 4/16 „Engineering of Expansion Compensation and Fixed Point“.)

Average values are always quoted for the utilization factors.

Functional endurance (on request)

Special cases

4

Overview

Standards

In Germany, the official certification of functional endurance in the event of fire must be provided to DIN 4102 Part 12.

Verification which applies are the test certificates and approvals for the respective positions issued by the material test institute for buildings in Braunschweig.

In the course of harmonisation, efforts are being made to adopt the German Standards throughout Europe.

Application

For certain applications, VDE 0108 requires that functional endu-rance of busbar trunking systems for supplying power to parts of installations be provided for an adequate time period, e.g.: E 90 = fire resistance period 90 min.

Fields of use with a high power requirement for which LX busbar trunking systems with functional endurance can be considered are, for example, standby power systems for supplying:• Passenger lifts with an evacuation circuit (E 30)• Water pressure boosting systems for fire-extinguisher water

supplies (E90)• Systems for dissipating smoke and heat in the event of a fire

(E 90)• Fire-service lifts (E 90).

The main field of application extends to installations having a fire resistance period of 90 minutes.

Overview

When transmitting power over long distances with LXA(C) bus-bar trunking systems, a voltage drop which varies in magnitude occurs. The voltage drop is influenced by the by the arrange-ment of the conductors.

The impedance values (details see Chapter „LXA/LXC Busbar Trunking System“ – Technical Data) and the voltage drop resul-ting from them are determined as a mean value during type tes-ting.

The use of three phase sequence reversal units has the effect that the magnitude of the voltage drop on all three phases cor-responds to the mean value. This means, that one phase se-quence reversal unit must be positioned after each third of the total length of the busbar run.

Phase sequence reversal units are available on request.

Application

Phase sequence reversal units are used where a low balanced voltage drop is to be achieved in a power transmission system and where power is carried over long distances at high load le-vels.
