WebAug 1, 2024 · With the high electric field, high temperature and mechanical stress, insulation materials experience degradation and finally dielectric breakdown in the long period of operation. Electrical tree, a pre-breakdown phenomenon that occurs in insulation materials, is the main issue to cause failures of high-voltage cables and cable accessories. A high-voltage cable (HV cable) is a cable used for electric power transmission at high voltage. A cable includes a conductor and insulation. Cables are considered to be fully insulated. This means that they have a fully rated insulation system that will consist of insulation, semi-con layers, and a metallic shield. This is in contrast to an overhead line, which may include insulation but not fully rated fo…
