High voltage cable is a type of power cable, which refers to the power cable used for transmission between (1KV=1000V), and is mostly used as the main road for power transmission The components of high-voltage cables from the inside out include: conductor, insulation, inner protective layer, filler (armor), and outer insulation. Of course, armored high-voltage cables are mainly used for underground burial, which can resist pressure on the ground and prevent damage from other external forces
