Copper Clad Steel (CCS) Wire

Copper Clad Steel (CCS) Wire is a kind of bimetallic material with inner carbon steel core bonded with an uniform layer of oxygen-free copper. It adopts cladding technology, combining the strength of steel as well as the good conductivity and corrosion resistance of copper to replace pure copper wires in many fields.

Copper Clad Steel (CCS) Wire ▼

Product Video ▼

Advantage of copper clad steel wire:▼

1. The copper clad steel wire by cladding is no pollution.

2. High tensile strength: CCS wire is suitable for overhead transmission lines.

3. Light weight: The length of the copper clad steel wire is bigger than the pure copper wire for the same specification.

4. Low loss: small linear expansion coefficient, good temperature endurance, low cost.
