The composition of electrical Wire

- Aug 30, 2017 -

The Wire and cable is composed of conductors, insulating layer, shielding layer and protective cover.


A conductor is a conductive part of a wire and cable that is used to transmit electricity and is the main part of a wire and cable.

Insulating layer

Insulating layer is the conductor and the Earth and different phase of the conductor between the electrical isolation, to ensure that electrical energy transmission, is an integral part of the wire and cable structure.

Shielding Layer

15KV and above wire and cable generally have a conductor shielding layer and insulation shielding layer.
