1. Core: The core is the conductive part of a power cable, used to transmit electrical energy and is the primary component of the cable.
2. Insulation: The insulation layer electrically isolates the core from the ground and between cores of different phases, ensuring power transmission. It is an essential component of the power cable structure.
3. Shield: Power cables of 15 kV and above generally have both a conductor shield and an insulation shield.
4. Protective layer: The protective layer protects the power cable from the intrusion of impurities and moisture, and from direct damage by external forces.
