ARRESTER WIRE / GROUND GALVANIZED STEEL WIRE (GSW or TK) AND ALUMNUM CLAD STEEL WIRE (AW)

LS Cable & System overhead wire is composed of ACSR and overhead ground wire. They are normally installed on steel towers, and recently the usage of high-capacity conductors for high-capacity transmission among power cables is increasing

Construction

Aluminum Conductors, Aluminum-Clad Steel Reinforced (ACSR/AW) 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.

Standard
