Steel Core Aluminum Standard Wire

Steel Core Aluminum Standard Wireis a type of high-capacity, high-strength stranded conductor typically used in overhead power lines. The outer strands are high-purityaluminium, chosen for its excellent conductivity, low weight and low cost. The center strand, or strands is/are of steel for additional strength to help support the weight of the conductor. Steel is higher strength than aluminium which allows for increased mechanical tension to be applied on the conductor. Steel also has lower elastic and inelastic deformation (permanent elongation) due to mechanical loading (e.g. wind and ice) as well as a lower coefficient of thermal expansion under current loading. These properties allow ACSR to sag significantly less than all-aluminium conductors.
