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.
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.
