The Structure of Electrical Wire

Structure of the Electrical Wire

The electric wire and cable is composed of four parts, the conductor, the insulating layer, the shielding layer and the protective layer.

(1) conductor

A conductor is a conductive part of a wire and cable that is used to transport electrical energy and is a major part of the copper wires and cables.

(2) insulation

The insulation layer is the conductor and the earth and the different phases of the conductor in the electrical isolation between each other, to ensure that the power transmission, is an indispensable part of the structure of the PVC electric cable.

(3) shielding layer

15KV and above wire and cable generally have the conductor shield layer and the insulation shield layer copper house wire.

(4) protective layer

The protective layer protects the electric wire and building cable from the intrusion of external impurities and moisture, as well as the protection of the power cable from direct damage to the external force.
