The basic structure of power cables by the core (conductor), an insulating layer, a shielding layer and a protective layer of four parts.

1. The core is conductive part of power cable, which is used to transfer power, is the main part of the power cable.

2. Insulation is the line between the core and the earth and the different phase of wire core in the electrical insulated from each other, is an indispensable part in the structure of power cable.

3. Shield  10KV power cable shielding layer and more generally have a conductor shielding layer and an insulating shielding layer.

4. Protective layer  The role of the protective layer is to protect the power cable from the outside world the invasion of the impurities and moisture, and prevent the external force directly damage the power cable.
