Basic structure of power cable
Jul 04, 2018

      The basic structure of the power cable consists of a core (conductor), an insulating layer, a shielding layer and a protective layer.

      Core: The core is the conductive part of the power cable that is used to carry electrical energy and is the main part of the power cable.

      Insulation: The insulation layer electrically isolates the core from the earth and the cores of different phases to ensure the transmission of electrical energy. It is an indispensable component of the power cable structure.

      Shield: Power cables of 15KV and above generally have a conductor shield and an insulating shield.

      Protective layer: The protective layer protects the power cable from external impurities and moisture, and prevents external forces from directly damaging the power cable.
