Recently, many customers have asked about the high voltage cable. If you want to reduce the expenses, you must maintain the high voltage cable when using it.
The surface of high voltage cable shall be kept clean, and damp, frozen, heated and pressed shall be avoided. The moisture of the cable infiltrates into the interior of the cable, reducing the insulation to be easily broken down; freezing makes the resin hard layer easy to crack and discharge.
When heated, it is easy to absorb water, expand and deform; when pressed, it will destroy the protective layer. 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.
