Note
- Coefficient of linear expansion 17.0 x 10-6/°C.
- Modulus of elasticity:
a. 119 GPa for seven (7) wire conductors.
b. 118 GPa nineteen (19) wire conductors.
b. 117 GPa for thirtyseven (37) wire conductors.
Current ratings are based on ambient temperature of 30°C, a maximum conductor temperature of 75°C, rural weathered, summer noon and intensity of solar radiation 1000 W/m².
