High voltage overhead transmission & distribution lines and coastal regions.
A higher UTS can be achieved by increasing core and higher current carrying capacity by increasing Al content. The mechanical properties of ACSR/AS conductors are similar to ACSR conductors, but they offer improved ampacity and resistance to corrosion because of the presence of aluminium clad steel wires in the core. These conductors are better replacement for ACSR conductors where corrosive conditions exist.
