Abstract

The invention discloses a power cable used in a nuclear power plant, which solves the problems that the existing power cable used in the nuclear power plant has low wear resistance, etc., and has the advantages of simple structure, convenient use and effectively improving the interference resistance of the cable, etc. The structure of the cable is characterized by comprising a multicore group conductor, the external wall of each conductor is coated with a insulating layer and arranged inside an obturator, the external wall of the obturator is provided with a cable double layer protecting sleeve and a wrap; the cable double layer protecting sleeve consists of an internal layer protecting sleeve and an external layer protecting sleeve, wherein, the internal layer protecting sleeve is a fluoroplastic protecting sleeve, and the external layer protecting sleeve is a low smoke zero halogen polyolefine protecting sleeve. The insulating layer includes internal layer insulation and external layer insulation, wherein, the internal layer insulation is a crosslinked polyethylene insulating layer and the external insulation is a low smoke zero halogen polyolefine insulating layer.

Description

Power cable for nuclear power plant
Technical field
The present invention relates to a kind of cable, relate 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.
Summary of the invention
Problems such as it is not good in order to solve its weather resistance of present power cable for nuclear power plant that purpose of the present invention is exactly, and 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 advantage such as cable weather resistance.
For achieving the above object, the present invention 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 invention 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 invention has the beneficial effects as follows: simple in structure, cost is low, good in anti-interference performance, and weatherability is strong, and accommodative ability of environment is strong, reliable operation.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein, 1, conductor; 2, primary insulation; 3, outer layer insulation; 4, twining package tape; 5, obturator; 6, internal layer sheath; 7, outer protective sleeve.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing and embodiment.
Among Fig. 1, a kind of power cable for nuclear power plant, it comprises multicore group conductor 1, and the outer wall wrap insulate layer of every conductor 1 also places in the obturator 5, and obturator 5 outer walls are provided with cable duplex sheath and twining package tape 4; The cable duplex sheath is made up of internal layer sheath 6 and outer protective sleeve 7; Wherein, internal layer sheath 6 is the fluoroplastics sheath, and outer protective sleeve 7 is the low-smoke halogen-free polyolefin protective cover material.Insulating barrier comprises primary insulation 2 and outer layer insulation 3; Wherein, primary insulation 2 is crosslinked polyetylene insulated layer; Outer layer insulation 3 is the low-smoke halogen-free polyolefin insulating barrier.
