Abstract
The utility model discloses a polyvinyl chloride insulation power cable, which comprises multiple conductors. The multiple conductors are divided into three groups, the multiple conductors in each group are stranded and bundled and then wrapped in a belting layer to form a cable core, each cable core is wrapped in a polyvinyl chloride insulation layer, and the polyvinyl chloride insulation layers of the three cable cores are all wrapped in a polyvinyl chloride inner sheath layer; the polyvinyl chloride inner sheath layer is wrapped in an oversheath layer; and a shielding layer formed by braided steel wires is arranged between the polyvinyl chloride inner sheath layer and the oversheath layer. Improvement in the utility model is simple, flame retardation of the polyvinyl chloride insulation power cable is improved while mechanical strength of the same is enhanced, and the polyvinyl chloride insulation power cable is more practical.
Description
Technical field
The utility model relates to a kind of cable, mainly is a kind of polyvinyl chloride insulation power cable.
Background technology
Power cable is the cable that is used to transmit and distribute electric energy, be usually used in the underground electrical network in city, power station lead line, industrial and mining enterprises in-line power and cross river, the submarine transmission line in sea excessively, the fire prevention that it should be noted is in case blast on fire will cause serious fire and power outage.Mostly be in actual the use to be mechanically damaged because of the insulating barrier of power cable, thereby cause the insulation breakdown that cable is alternate, the electric arc of generation makes insulating material and cable external protection material combustion on fire.Main its fire retardant performance of emphasis in the manufacture process of existing power cable, thereby ignored its mechanical strength.
The utility model content
Technical problem to be solved in the utility model provides a kind of polyvinyl chloride insulation power cable, and it improves simple, has increased its mechanical strength when improving fire resistance, and practicality is better.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of polyvinyl chloride insulation power cable, include a plurality of conductors, it is characterized in that: described a plurality of conductors are divided into three groups, be around with a band behind the stranded bunchy of a plurality of conductors in every group and constitute core, described every group of core is coated with the polyvinyl chloride insulation layer outward respectively, the polyvinyl chloride insulation layer of described three groups of cores is coated with the polyvinyl chloride inner restrictive coating outward jointly, described polyvinyl chloride inner restrictive coating is coated with external sheath layer, is provided with the screen that one deck is made of braided steel wire between described polyvinyl chloride inner restrictive coating and the external sheath layer.
Described external sheath layer is to be extruded in outside the screen of braided steel wire after mixing by fire-retardant acrylonitrile-butadiene rubber.
Polyvinyl chloride has fire resistance, chemical proofing height in the utility model, its mechanical strength and electrical insulation capability are also cried out good simultaneously, thereby strengthened the mechanical performance of power cable, be provided with the screen that one deck is made of braided steel wire simultaneously, can not only play the effect of shielding, and steel wire has also strengthened its intensity.
The utility model has the advantages that:
The utility model improves simple, has increased its mechanical strength when improving fire resistance, and practicality is better.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, a kind of polyvinyl chloride insulation power cable, include a plurality of conductors 1, described a plurality of conductor 1 is divided into three groups, be around with a band 2 behind a plurality of conductors 1 stranded bunchy in every group and constitute core 3, described every group of core 3 outer polyvinyl chloride insulation layers 4 that are coated with respectively, the polyvinyl chloride insulation layer 4 outer polyvinyl chloride inner restrictive coating 5 that is coated with jointly of described three groups of cores, described polyvinyl chloride inner restrictive coating 5 is coated with external sheath layer 6, is provided with the screen 7 that one deck is made of braided steel wire between described polyvinyl chloride inner restrictive coating 5 and the external sheath layer 6.
Described external sheath layer 6 is to be extruded in outside the screen of braided steel wire after mixing by fire-retardant acrylonitrile-butadiene rubber.
