7/1.0mm Hard Drawn Copper

The wires in all bare conductors are stranded concentrically with successive layers having an opposite direction of lay, the outermost layer being right-handed.

Note Current ratings are based on the following conditions

• Conductor temperature rise above ambient of 40°C
• Ambient air temperature of 35°C for summer noon or 10°C for winter night
• Direct solar radiation intensity of 1000W/m² for summer noon or zero for winter night
• Diffuse solar radiation intensity of 100W/m² 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 weathered conductor
• Solar absorption coefficient of 0.5 for rural weathered or 0.85 for industrial weathered conductor
