Application
AAAC - All Aluminium Alloy Conductor
AAAC aerial conductor has a high tensile strength, good corrosion resistance, light weight and comparable current carrying capacity.
It is designed for medium and long spans, can be used for LV and MV distribution networks.
Note
- GC = Greased Core
- Coefficient of linear expansion 23.0 x 10-6/°C.
- Modulus of elasticity:
a. 65 GPa for seven (7) and nineteen (19) wire conductors.
b. 64 GPa for thirtyseven (37) and sixtyone (61) 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.
