AAAC 2/0AWG (stranding:7/3.50mm) All Aluminum Alloy Conductor Bare Aluminum Conductor ASTMB399/399M
APPLICATION: AAAC is mainly used as bare overhead transmission cable and as primary and secondary distribution cable. It is also suitable for laying across basins, rivers and valleys where special geographical teatures exist.
STANDARD
ASTM B232 Concentric-Lay-Stranded Aluminum Conductors, Coated Steel
Reinforced (ACSR)
BS 215: Part 2 Aluminum Conductor, Steel Reinforced For Overhead
Power Transmission
DIN 48204 Steel Reinforced Aluminum Stranded Conductors
NFC 34-120 Conductoare din otel-aluminiu
GOST 839-1980 Conductoare din otel-aluminiu
CONSTRUCTION
AAAC cable bvconsists of aluminum alloy wires. The aluminum alloy wires are concentrically stranded.
This section deals with heat-treatable magnesium silicon type aluminium alloys to the applicable International Standard, the electrical and mechanical properties of which all fall within the values suggested by relevant standard. Conductors to all other recognized specifications can also be supplied. The alloys referred to have higher strength but lower conductivity than pure aluminium. Being lighter, alloy conductors can sometimes be used to advantage in place of the more conventional ACSR; Having lower breaking loads than the later, their use becomes particularly favourable when ice and wind loadings are low.
(*) Note: The values of current rating mentioned in above Table are based on wind velocity of 0.6 metre/second, solar heat radiation of 1200 watt/metre2, ambient temperature of 50° C & conductor temperature of 80°C.
