How is the main structure of the high-voltage cable composed?

Extrude (wind) the insulation layer outside the conductor, twist several cores (corresponding to the phase wire, neutral wire and ground wire of the power system), and add a sheath layer, such as plastic/rubber wire and cable. The main process technologies include drawing, stranding, insulation extrusion (wrapping), cable formation, armoring, sheath extrusion, etc. There are certain differences in the different process combinations of various products.
Power cables are classified into low-voltage cables, medium-voltage cables, and high-voltage cables according to voltage levels. According to the insulation conditions, it is divided into plastic insulated cables, rubber insulated cables, mineral insulated cables and so on. A voltage level greater than 35KV is called a high-voltage cable.High Voltage Cables
