IntroductionThe MK Ega metal cable trunkings, trays and ladders are

designed for surface mounting to enclose electrical power,

telephone, computer, fibre optic, and structured cablings

which form part of the wide range of MK Cable Management

Systems to meet the needs of wiring installations in

buildings.

Designed to meet BS, IEC and SS standards, they areproduced under strict quality control and using the latest full

automation, computerised high-tech precision machineries.

The state of art powder coating lines are the latest in

technology making the finishes of the products of the highest

quality. The precision parts manufactured make the whole

system completely interchangeable and ensure fast and

easy installation. It ensure a pleasant continuous run with

smooth joints, strength and straightness.

Combined with other patented MK Ega products such as

Underfloor trunking system and PVC trunkings, just to name

a few, will provide a total solution.

We provide total solutions in steel cable support system. Cable

support systems are available in three confirgurations: Cable

trunking, cable tray and cable ladder. The type of support

best suited for an application will depend on many factors

including the nature of the cables to be installed, the site

conditions and aesthetics.

We ensure that all of the materials used during the

construction and finishing of their products conform to the

relevant standards. In particular, the relevant standards for

steel are:

• Pre-galvanised BS 10143 : 1993

• Mild Steel BS 1449 : Part 1

• Electro-galvanised BS EN10152 : 1994

• Stainless Steel AISI 304, 316 or 316L

Technical

Using high quality grade steel with electro-galvanised,

pre-hot dip galvanised or post hot dip galvanising ensure

the Ega cable truckings, trays and ladders meet the high

standard requirements of the relevant specifications against

corrosion and mechanical strength. For products that are

powder coated, high grade polyester powder coating with

minimum 45 micron thickness ensure excellent protection

against chemical corrosion as well as adding aesthetic and

colour codings.

MK Ega range of steel cable support systems are tested and

surpasses the stringent requirements of salt-spray test. This

guarantees our products will withstand the high humidity in

tropical weather conditions.

All MK Ega products are designed with very low earthing

resistance continuity bonding. The electrical continuity tests

were conducted by the relevant test authorities and surpassed

the latest specifications requirement.

Several types of fastenings for trunking covers are available

besides the screw fixed method. The quick fix turn clamps

are available on request.

A wide range of Ega factory manufactured accessories for

the cable trunkings, trays and ladders will provide quick and

high quality installation.

The MK Ega range of metal cable support and enclosure

system complies to the relevant specifications, ie. BS 4678,

SS249 and IEC 61084. For products that are to manufacturer

standards; Declaration of Compliance according to ISO Guide

22 can be provided.

MK Electric is an ISO 9002 certified manufacturer and

supplier.
