A high-voltage cable (HV cable) is a cable used for electric power transmission at high voltage.
High-voltage cables are manufactured up to a maximum voltage of 170 kV. They are plastic cables insulated using cross-linked polyethylene (XLPE), representing first-class insulation technology. High-voltage cables are manufactured of aluminum or copper.
High Voltage XLPE Cable is now dominant in new transmission lines for both land and submarine applications.
