Copper-covered-steel conductor electric wire and cable

The utility model discloses a copper-clad steel conductive wire and cable, comprising a conductor and an insulation layer arranged outside the conductor; the conductor comprises a steel core; a copper layer is evenly plated on the surface of the core. A coating layer is plated on the surface of the copper layer; the coating layer can be a tin layer or nickel layer or silver layer. The copper-clad steel conductive wire and cable of the utility model uses the steel core to replace part of copper in use so as to greatly reduce the consumption of copper material and make the cost lower; as the copper-clad steel conductor is soft, the copper layer on the surface of the steel core still has the conductive effects; the conductive properties of copper-clad steel conductive wire and cable is as ideal as that of a bare copper conductor, while the mechanical strength of the cable is better than that of the bare copper conductor, so that the copper-clad steel conductive wire and cable can be used in various fields for power and signal transmission.
