AAAC conductor is made from aluminum-magnesium-silicon alloy of high electrical conductivity containing enough magnesium silicide to give it better mechanical properties after treatment. These conductors are generally made out of aluminum alloy 6201. AAAC CONDUCTOR has a better corrosion resistance and better strength to weight ratio and improved electrical conductivity than ACSR CONDUCTOR on equal diameter basis.
The alloys referred to have higher strength but lower conductivity than pure aluminum . Being lighter , alloy conductors can sometimes be used to advantage in place of the more conventional ACSR ; having lower breaking loads than the latter , their use becomes particularly favorable when ice and load are low.
