Recently, many customers have inquired about our high voltage cable. High voltage cable is composed of many layers, semiconductor layer, metal shielding layer and protective layer. The semiconductor layer is made of semiconductor material and black rubber with a thickness of 1-1.5mm. The effect is to eliminate the electrostatic field between the outer surface of the insulating layer and the metal shielding layer.The function of the protective layer is to strengthen the mechanical protection of the high voltage cable, reduce the external damage, and prevent the harmful gas and oil pollution and ultraviolet radiation on the high voltage cable.
