(a) Wind Speed 1m/sec, emissivity 0.5, absorptance 0.5. Air temperature 10°C for winter night, 35°C for summer noon. Intensity of solar radiation 1000 W/m² for summer noon. Angle of wind to conductor axis is 60o in summer noon. For current ratings at different conductor operating temperatures, refer to the graph on next two pages. Calculation based on IEEE Std 738 – 1993.

APPLICATION
7 and 19 strand construction is suitable for bare overhead reticulation of medium spans, normally at low and medium voltages. 37 and 61 strand construction is suitable for transmission and subtransmission lines where homogeneous construction can reduce line losses and improve corrosion resistance in conductors with similar strength to ACSR types
