AAAC is widely used in power transmission lines with various voltages. This type of conductor is made from aluminium-magnesium-silicon alloy of high electrical conductivity containing enough magnesium silicide to give it better mechanical properties after treatment. AAAC conductor has better corrosion resistance and better strength to weight ratio and improved electrical conductivity than ACSR conductor on equal diameter basis. AAAC can carry at least 15-20% extra current as compared to ACSR of equal size.
