Construction
Aluminum Conductors, Steel-Reinforced (ACSR) is a concentric-lay-stranded conductor consisting of galvanized steel central core with one or more layers of hard drawn stranded aluminum wires laid helically over the steel core. Steel core wires are protected from corrosion by galvanization.
Additional corrosion protection is available through the application of grease.
