Abstract

The utility model discloses a composite power cable. The cable comprises a cable core. The cable core comprises a central grounding wire core conductor and five power wire cores around the central conductor. Each power wire core is prepared by stranding five power conductors and then covering the power conductors with a ceramic fiber woven layer. The grounding wire core conductor and the power conductor are both prepared by stranding tin-coated copper wires and nickel-coated copper wires. The grounding wire core conductor and the power conductor are both covered by a polyimide insulation layer. The cable core is sequentially covered by an ethylene propylene diene monomer layer, a three-layer zinc-coated steel belt armored layer, a chlorosulfonated polyethylene inner protection sleeve, a magnesium-silicon alloy silk woven layer, and an outer protection layer, from the inside to the outside, wherein the outer protection layer is composed of a polyvinyl chloride layer, a polyester fiber layer, and a polyvinyl chloride layer from the inside to the outside. The composite power cable is provided with an ethylene propylene diene monomer layer, a three-layer zinc-coated steel belt armored layer, a chlorosulfonated polyethylene inner protection sleeve, and a magnesium-silicon alloy silk woven layer, so the cable has a very good tensile property and electromagnet shielding performance, is very safe and reliable, and has a very good stability.
