(a) Wind Speed 1m/sec, emissivity 0.5, absorptance 0.5. Air temperature 10C for winter night, 25C for summer noon. Intensity of
solar radiation 1000 W/m for summer noon. Angle of wind to conductor axis is 60o. For current ratings at different conductor
operating temperatures, refer to the graph on next two pages.
Calculation based on IEEE Std 738 1993.
