AP1000 main pump frequency conversion cable

The utility model provides an AP1000 main pump frequency conversion cable, and belongs to the technical field of cables. The AP1000 main pump frequency conversion cable comprises a cable core and a sheath. The cable core is composed of three phase wires, three zero wires and one temperature-sensitive optical fiber unit. The zero wires are respectively arranged in an interval between two adjacent phase wires. The temperature-sensitive optical fiber unit is arranged in the center of the cable core. Each phase wire is formed in such a manner that a circular copper conductor is provided with a conductor shielding layer, an insulating layer and an insulating shielding layer in sequence. Each zero wire is formed in such a manner that a formed copper conductor with a fan-shaped cross section is provided with a formed insulating layer. The fan angle of the fan-shaped copper conductor is 120 degrees. The fan angle faces the center of the cable core. The cable core is wrapped by a wrapping tape I. A ceramic silicone rubber heatproof moisture-protection layer is extruded on the wrapping tape I. A copper wire shielding layer is wound on the heatproof moisture-protection layer. The copper wire shielding layer is wrapped by a superconductive tape wrapping layer. The superconductive tape wrapping layer is wrapped by a wrapping tape II. The sheath is extruded on the wrapping tape II. The AP1000 main pump frequency conversion cable is reasonable in structure and safe, the requirements of an AP1000 main pump frequency conversion device to the cable are met, and the requirement of 60 years of service lifetime of the cable is met.
