Recently received a customer consultation, the customer bought our company’s high voltage cable in May last year, asking about maintenance problems. The surface of high voltage cable shall be kept clean, and damp, frozen, heated and pressed shall be avoided. The moisture of the cable seeps into the interior of the cable, which reduces the insulation and is easy to be broken down;

When frozen, the hard layer is easy to crack and discharge; when heated, it will absorb moisture and expand and deform; when pressed, it will destroy the protective layer of metal mesh. It is necessary to prevent the insulating oil from eroding the high-voltage cable, because the insulating oil has a strong corrosive effect on the rubber.
