These are made out of high strength Aluminium-Magnesium-Silicon alloy. As compared to conventional ACSR, AAAC are of lighter weight, comparable strength & current carrying capacity, lower electrical losses and superior corrosion resistance, This has given AAAC a wide acceptance in the distribution and transmission lines.. This conductor has a minimum conductivity of 52.5% IACS. All the wires have the same nominal diameter. Most common constructions consist of 7, 19, 37 and 61 wires.
