Product Description

240mm2 37x2.87mm (1x37-20.09mm) Annealed Copper Earthing Grounding Conductor

CCS wire is formed through electroplating method (taking steel wire as the core and depositing the copper layer evenly on the surface of the steel core) and cladding method (Cladding planished copper stripe concentrically on the outer surface of the steel core).

Product Parameters

Copper clad steel wire (CCS) combines the high tensile strength of steel as its core and the conductivity properties of copper as its outer layer. The core material is usually low carbon steel and is typically used as either grounding wire or the inner conductor of coaxial cables. Copper clad steel is made to ASTM B-452 standards with 40% conductivity in two tempers: soft and hard drawn.

70A	0.026524	8.58	15.0

Advantage

1.The copper clad steel wire by cladding in no pollution.
2.High tensile strength:this kind of 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.

Application:
Telephone wire CATV cable
electrical power communication overhead wire
High temperature conductor Intemet cable
Comouter cable Electronics contact fittings Shielded line of electric power cable
