Application

ACSR/AC can be used in Medium, High and Extra-High voltage transmission lines; also used for earth wires. In comparison with ACSR conductors, ACSR/AW conductors have considerable technical and economical advantages in overhead lines. Its lower weight combined with its higher current carrying capacity and corrosion protection provide a longer life cycle, reduction in energy losses and significant cost saving during the operation of the line.

Construction

ACSR/AC – Aluminium Conductors, Aluminium Clad Steel Reinforced is a concentric-lay-stranded conductor consisting of aluminum-clad steel central core (AW) with one or more layers of hard drawn stranded aluminum wires. The AW core is a highly resistant steel rod, covered with a thick coating of pure aluminum.
