Power cable Structure

 

 

 

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. 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.
