The utility model provides a PVC insulation and sheath inflaming-retarding fireproof power cable comprising a plurality of cable cores, wherein the plurality of cables cores are twisted and then are wrapped by a tape wrapping layer. A PVC insulation layer is arranged outside the tape wrapping layer, a middle fireproof layer is mounted outside the PVC insulation layer, an inner inflaming-retarding layer is disposed outside the middle fireproof layer, an outer fireproof layer is arranged outside the inner inflaming-retarding layer, an outer inflaming-retarding layer is disposed outside the outer fireproof layer an armor layer is mounted outside the outer inflaming-retarding layer and a PVC sheath layer is disposed outside the armor layer. The cable core comprises a conductor, an inner insulation layer is arranged outside the conductor, a shielding layer is mounted outside the inner insulation layer, a protective layer is disposed outside the shielding layer and an inner fireproof layer is arranged outside the protective layer. The power cable provided by the utility model has the advantages of simple structure, good intensity, convenient manufacturing, high temperature resistance, excellent inflaming-retarding performance, excellent anti-aging performance and long service life.
Description
Technical field
The utility model 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 for transmission and distributes the electric equipment of electric energy, and in power circuit, the shared proportion of cable increases gradually, and the Main Function of power cable is transmission and distribute 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 lsafety level of electric wiring and the fire-retardant problem of cable more and more cause people's concern, the fire resistance of simultaneously present cable is relatively poor, in case breaking out of fire, particularly intensive some the important occasions such as 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 caused certain infringement.
Summary of the invention
In order to address the above problem, the utility model provide a kind of fire-resistant effective, insulating reliability 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 utility model is achieved through the following technical solutions:
The utility model is a kind of polyvinyl chloride insulation and shield sleeve flame, fireproof power cable, comprise several cable cores, tie up stranded rear the twining by belting layer of several cable cores, arranged outside at belting layer has the polyvinyl chloride insulation layer, arranged outside at the polyvinyl chloride insulation layer has middle flame retardant coating, arranged outside at middle flame retardant coating has interior flame-retardant layer, arranged outside at interior flame-retardant layer has outer flame retardant coating, the arranged outside of flame retardant coating has outer flame-retardant layer outside, the arranged outside of flame-retardant layer has armour outside, in the arranged outside of armour the pvc sheath layer is arranged.
Further improvement of the utility model is: cable core comprises conductor, in the arranged outside of conductor inner insulating layer is arranged, and in the arranged outside of inner insulating layer screen is arranged, and at the arranged outside matcoveredn of screen, in the arranged outside of protective layer interior flame retardant coating is arranged.
Further improvement of the utility model is: armour is the armour that the finer wire braiding forms.
Further improvement of the utility model is: protective layer uses waterproofing rope to fill.
The beneficial effects of the utility model are: cable of the present utility model has adopted three layers of flame retardant coating, so that the fire-resistant effect of cable improves, flame retardant coating can effectively prevent hydracid corrosive gas harmful to human and the equipment that cable discharges when the breaking out of fire after-combustion produces the substance combustion of a large amount of dense smokes and Halogen, the utility model 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, prolong the useful life of cable.
The utility model is simple in structure, and intensity is good, and is easily manufactured, high temperature resistant, and anti-flammability is tender good, and ageing resistace is superior, long service life.
