ACSR cable is concentrically stranded conductor with one or more layers of hard drawn electrolytic grade aluminium wire on galvanized high tensile steel wire core. The core can be single wire or stranded depending on the size of the conductor. Steel core wire is galvanised for corrosion protection. The weight of zinc coating per unit length of steel core wire is dependent on the standard adopted. Additional corrosion protection is available through the application of grease to the core.
