Abstract
The invention discloses a polyvinyl chloride insulation and sheath flame-retardant and fire-proof power cable which comprises a plurality of cable cores. After being twisted, the cable cores are wrapped by a wrapping tape layer. A polyvinyl chloride insulation layer is arranged on the outer side of the wrapping tape layer. A middle fire-proof layer is arranged on the outer side of the polyvinyl chloride insulation layer. An inner flame-retardant layer is arranged on the outer side of the middle fire-proof layer. An outer fire-proof layer is arranged on the outer side of the inner flame-retardant layer. An outer flame-retardant layer is arranged on the outer side of the outer fire-proof layer. An armor layer is arranged on the outer side of the outer flame-retardant layer. A polyvinyl chloride sheath layer is arranged on the outer side of the armor layer. Each cable core comprises a conductor, wherein an inner insulation layer is arranged on the outer side of the conductor, a shielding layer is arranged on the outer side of the inner insulation layer, a protective layer is arranged on the outer side of the shielding layer, and an inner fire-proof layer is arranged on the outer side of the protective layer. The polyvinyl chloride insulation and sheath flame-retardant and fire-proof power cable is simple in structure, good in strength, convenient to manufacture, resistant to high temperature, good in flame-retardant performance, superior in anti-aging performance and long in service life.
Description
Technical field
The present invention relates to a kind of power cable, specifically a kind of polyvinyl chloride insulation and shield sleeve flame, fireproof power cable.
Background technology
Power cable is the electric equipment for transmitting and distribute electric energy, and in power circuit, the shared proportion of cable increases gradually, and the Main Function of power cable is transmission and distribution high-power power in the basic routing line in electric power system.There is the poor and incendive problem of structural stability in existing common cable, therefore the fire-retardant problem of the lsafety level of electric wiring and cable more and more causes people's concern, the fire resistance of simultaneously current cable is poor, once breaking out of fire, particularly some important occasions such as intensive market, skyscraper, subway and industrial and mining enterprises of personnel can cause damage to people's lives and properties, and the hydracid corrosive gas that produces of burning cable can harmful to human and the illumination of rescue aid is caused to certain infringement.
Summary of the invention
In order to address the above problem, the invention provides that a kind of fire-resistant effective, insulating reliability is large, the polyvinyl chloride insulation of good flame retardation effect and shield sleeve flame, fireproof power cable.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is a kind of polyvinyl chloride insulation and shield sleeve flame, fireproof power cable, comprise several cable cores, after several cable cores are stranded, twine and tie up by belting layer, there is polyvinyl chloride insulation layer in the arranged outside of belting layer, there is middle flame retardant coating in the arranged outside of polyvinyl chloride insulation layer, there is interior flame-retardant layer in the arranged outside of middle flame retardant coating, there is outer flame retardant coating in the arranged outside of interior flame-retardant layer, the arranged outside of flame retardant coating has outer flame-retardant layer outside, the arranged outside of flame-retardant layer has armour outside, has pvc sheath layer in the arranged outside of armour.
Further improvement of the present invention is: cable core comprises conductor, has inner insulating layer in the arranged outside of conductor, has screen in the arranged outside of inner insulating layer, at the arranged outside matcoveredn of screen, has interior flame retardant coating in the arranged outside of protective layer.
Further improvement of the present invention is: armour is that finer wire weaves the armour forming.
Further improvement of the present invention is: protective layer uses waterproofing rope to fill.
The invention has the beneficial effects as follows: cable of the present invention has adopted three layers of flame retardant coating, the fire-resistant effect of cable is improved, flame retardant coating can effectively prevent hydracid corrosive gas harmful to human and the equipment that cable discharges in the time that breaking out of fire after-combustion produces the substance combustion of a large amount of dense smoke and Halogen, the present invention has also adopted dielectric layers, the insulating reliability of polyvinyl chloride insulation layer is large, two-layer flame-retardant layer and pvc sheath layer have played good flame retardant effect, extend the useful life of cable.
The present invention is simple in structure, and intensity is good, easily manufactured, high temperature resistant, and anti-flammability is tender good, and ageing resistace is superior, long service life.
