Abstract
The utility model discloses a high frequency power cable, and belongs to the cable technology field. The high frequency power cable includes an inner conductor, an insulating layer, an outer conductor, a shielding layer and a sheath. The inner conductor is arranged in the center of the high frequency power cable and is formed by twisting 19 single-core leads. The insulating layer is coated on the outside of the inner conductor. The outer conductor also includes 19 single-core leads which are evenly arranged on the periphery of the insulating layer. The shielding layer is formed by weaving two layers of tin-coated copper wires, and the shielding layer is coated on the periphery of the outer conductor. The sheath is coated on the periphery of the shielding layer. Through adopting the above technical scheme, the high frequency power cable is high-temperature-resistant and corrosion-resistant, and the skin effect and the interference problem of the high frequency current are solved.
