Wire composition


Wires and cables are composed of conductor, insulating layer, shielding layer and protective layer.
Conductor is the conductive part of wire and cable, which is used to transmit electric energy. It is the main part of wire and cable.
Insulating layer
The insulating layer is an indispensable part of the wire and cable structure, which electrically isolates the conductor from the earth and the conductors of different phases to ensure the transmission of electric energy.
Shielding layer
Wires and cables of 15kV and above generally have conductor shielding layer and insulation shielding layer.
Protective layer
The function of the protective layer is to protect wires and cables from the invasion of external impurities and moisture, and to prevent external forces from directly damaging power cables.
