Structure:

The components of a high-voltage cable from the inside out include: conductor, insulation, inner sheath, filling material (armor), and outer insulation. Of course, armored high-voltage cables are mainly used for burial, as they can withstand intense pressure on the ground and also prevent damage from external forces.

Cables act as the bridge between power supply equipment and electrical equipment, facilitating the transmission of electrical power. Faults occur frequently. The following is a brief analysis of the causes of common issues in high-voltage cables, categorized by the causes of faults into the following main categories: manufacturer production reasons, construction quality reasons, design unit design reasons, and external force damage.
