Product Description

Product Description

Copper Clad Steel (CCS) wire is a composite material in which a concentric copper cladding is metallurgically bonded to a steel core through a continuous, solid cladding process using pressure rolling for primary bonding. The copper cladding thickness remains constant surrounding the steel core. It measures 6% of the overall wire diameter for 30% conductivity wires and 10% of the overall wire diameter for 40% conductivity wires. Different steel grades for the core result in Dead Soft Annealed, High Strength, and Extra High Strength characteristics. Strand is concentrically stranded cable of one to three layers with a left-hand lay in the outer layer, unless otherwise specified. All individual wires are of the same size. The CCS wire and strand combine the strength of steel with the conductivity and corrosion resistance of copper. These properties make CCS wire and strand ideal for many utility, telecommunication, and general industry applications.
