Abstract

The utility model discloses an electric power radio frequency cable. The cable is formed by an aluminum wire core, nickel wire cores, a semiconductor filling layer, a polyvinyl chloride insulation layer, a silicone rubber insulation layer, an aluminum belt shielding layer, a chloroprene rubber sheath layer, a low-smoke halogen-free polyolefin sheath layer and aluminum alloy wire cores. One semiconductor filling layer wraps the aluminum wire core. The four nickel wire cores and the four aluminum alloy wire cores are extruded in the semiconductor filling layer simultaneously. The nickel wire cores and the aluminum alloy wire cores are arranged with intervals. One silicone rubber insulation layer is extruded outside the polyvinyl chloride insulation layer. One aluminum belt shielding layer is extruded outside the silicone rubber insulation layer. Two sheath layers wrap the aluminum belt shielding layer, wherein the two sheath layers are the chloroprene rubber sheath layer and the low-smoke halogen-free polyolefin sheath layer. The cable of the utility model possesses the following advantages that flame retardant performance is possessed; a coefficient of thermal expansion is low and stable; the cable is not easy to corrode by acid and alkali and possesses heat tolerance performance.
