Abstract
The utility model discloses an electric power cable of a nuclear power station, which solves the problems of low wear-resistant degree of the prior nuclear power of the nuclear power station, has the advantages of simple structure and convenient use and can effectively improve the anti-jamming capability of the cable, and the like. The electric power cable of the nuclear power station comprises a plurality of core groups of conductors, and an insulating layer is wrapped around the outer wall of each conductor which is arranged in a filling body; a wrapping strip and a double-layer protective sleeve for the cable are arranged on the outer wall of the filling body, and the double-layer protective sleeve for the cable comprises an internal-layer protective sleeve and an external-layer protective sleeve, wherein the internal-layer protective sleeve is a fluoroplastic protective sleeve, and the external-layer protective sleeve is made of low-smoke and halogen-free polyolefin protective sleeve material; the insulating layer comprises an internal-layer insulating layer and an external-layer insulating layer, wherein the internal-layer insulating layer is a crosslinked polyethylene insulating layer, and the external-layer insulating layer is a low-smoke and halogen-free polyolefin insulating layer.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of power cable for nuclear power plant.
Background technology
The present used cable of nuclear power station is in cost consideration and mostly is the individual layer sheath, this just causes the weather resistance of cable and wear-resistant degree not high, especially power cable for nuclear power plant its any problem can not appear to wear-resistant and weather-proof ability, and existing individual layer protective-cover type structure can't meet the demands.
The utility model content
The purpose of this utility model is exactly not good in order to solve its weather resistance of present power cable for nuclear power plant, problems such as wear-resistant degree is low, provide a kind of and have simple in structurely, easy to use, can effectively improve the power cable for nuclear power plant of advantages such as cable weather resistance.
For achieving the above object, the utility model adopts following technical scheme:
A kind of power cable for nuclear power plant, it comprises multicore group conductor, and the outer wall wrap insulate layer of every conductor also places in the obturator, and described obturator outer wall is provided with cable duplex sheath and twining package tape;
Described cable duplex sheath is made up of internal layer sheath and outer protective sleeve; Wherein, the internal layer sheath is the fluoroplastics sheath, and outer protective sleeve is the low-smoke halogen-free polyolefin protective cover material.
Described insulating barrier comprises primary insulation and outer layer insulation; Wherein, primary insulation is crosslinked polyetylene insulated layer; Outer layer insulation is the low-smoke halogen-free polyolefin insulating barrier.
Power cable for nuclear power plant of the present utility model all adopts double hyer insulation, and primary insulation is a cross-linked polyethylene insulating material, and outer layer insulation is the low-smoke halogen-free polyolefin Insulation Material; Sheath adopts duplex sheath, and the internal layer sheath is fluoroplastics, and outer protective sleeve is the low-smoke halogen-free polyolefin protective cover material, and performance is with reference to other patents.
The protective action of the existing sheath in the past of duplex sheath has strengthened the weatherability of cable again, makes the environment for use of cable more extensive.Insulation Material adopts cross-linked polyethylene insulating material, has reduced dielectric loss in use, has strengthened electrical property, makes transmission signals more stable and undistorted, thereby ensures the effective transmission of cable.
The beneficial effects of the utility model are: simple in structure, cost is low, good in anti-interference performance, and weatherability is strong, and accommodative ability of environment is strong, reliable operation.
