ACSR/AS or ACSR/AW overhead bare conductor

ACSR/AS or ACSR/AW – The full name: Aluminium Conductors, Aluminium Clad Steel Reinforced. They are  concentrically stranded conductors with one or more layers of hard drawn 1350-H19 aluminium wires on Aluminium Clad steel wire core. The core can be single wire or stranded depending on the size.

Primarily used as the phase conductor for overhead transmission and distribution. It is preferred over conventional ACSR because of its higher corrosion resistance, lighter weight, longer service life, and reduced power loss.

Construction

Aluminum alloy 1350-H19 wires, concentrically stranded about an aluminum-clad steel core.
