| Note : current ratings are based on following condition |
| |
| » conductor temperature rise above ambient of 40 ºC |
| » Ambient air temp of 35 ºC or summer noon or a0 ºC for winter night |
| » Direct solar radiation intensity of 1000W/m ² for summer noon or zero for winter night |
| » Diffuse solar radiation intensity of 100W/m ² for summer noon or zero for winter night |
| » Ground reflectance of 0.2 |
| » Emissivity of 0.5 for rural weathered conductor or 0.85 for industrial weather conductor |
| » Solar absorption coefficient of 0.5 for rural weathered conductor or 0.85 for industrial weathered conductor |
