Description
Technical field
This utility model relates to power transmission device field, is specially a kind of PVC insulated power cable.
Background technology
Along with the fast development of national economy, as the electric wire of national economy aorta, its consumption and range
Increasing.In recent years, the industry such as power plant, transformer station and petrochemical industry, very big to the demand of cable.
At present, the cable on market is various, and they are applied in various different occasions.But major part cable is typically
Wire outer surface covers one layer of plastic layer, the most damaged and aging, and layer of structure arranges unreasonable, the most not
Compact, conductor shape is more single, and packed layer is the most solid firmly, and filling effect is the best, and insulating barrier insulation effect is undesirable, holds
Easy electromagnetic wave affects, and restrictive coating is fragile, and whole service life is shorter.
Summary of the invention
The purpose of this utility model is to provide a kind of PVC insulated power cable, to solve in above-mentioned background technology
The problem proposed.
For achieving the above object, this utility model following technical scheme of offer: a kind of PVC insulated power cable, bag
Including cable body, wire, polychlorostyrene insulating barrier, overcoat, flame-retardant layer and oversheath, described cable body central authorities are provided with steel wire；
It is provided with wire outside described steel wire；Polyvinyl chloride insulation layer it is provided with outside described wire；Described polyvinyl chloride insulation layer it
Between be provided with gauze screen；It is provided with overcoat outside described gauze screen；Described steel wire and gauze screen and overcoat and gauze screen it
Between be filled with packed layer；It is provided with flame-retardant layer outside described overcoat；It is provided with oversheath outside described flame-retardant layer.
Preferably, described packed layer uses composite material of silicon carbide to fill.
Preferably, described flame-retardant layer is halogen-free and low-smoke flame-retardant polyolefin layer.
Preferably, described gauze screen uses copper wire to make.
Preferably, described wire is provided with four, and uses copper material to make.
Compared with prior art, the beneficial effects of the utility model are: this utility model uses polyvinyl chloride insulation layer bag
Wrapping up in wire, radiating insulating performance is fabulous, and steel wire is shared stress when wire is set up thus strengthened pullling of lead body
Intensity, is provided with brass wire shielding net outside polyvinyl chloride insulation layer, cuts off the impact that wire is produced by the factors such as external electromagnetic,
Making electric current transmission more stable, flame-retardant layer is halogen-free and low-smoke flame-retardant polyolefin layer, intercepts the external heat source impact on wire.
Accompanying drawing explanation
Fig. 1 is this utility model cross section structure schematic diagram.
In reference: 1-cable body；2-wire；3-polychlorostyrene insulating barrier；4-overcoat；5-flame-retardant layer；6-oversheath；
7-steel wire；8-gauze screen；9-packed layer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, a kind of embodiment that this utility model provides: a kind of PVC insulated power cable, including electricity
Cable body 1, wire 2, polychlorostyrene insulating barrier 3, overcoat 4, flame-retardant layer 5 and oversheath 6；Cable body 1 central authorities are provided with steel wire 7；
Steel wire 7 is outside is provided with wire 2；Wire 2 is outside is provided with polyvinyl chloride insulation layer 3；It is provided with between polyvinyl chloride insulation layer 3
Gauze screen 8；Gauze screen 8 is outside is provided with overcoat 4；It is filled with between steel wire 7 and gauze screen 8 and overcoat 4 and gauze screen 8
Fill layer 9；Overcoat 4 is outside is provided with flame-retardant layer 5；Flame-retardant layer 5 is outside is provided with oversheath 6.
Packed layer 9 uses composite material of silicon carbide to fill；Flame-retardant layer 5 is halogen-free and low-smoke flame-retardant polyolefin layer；Gauze screen 8 is adopted
Make with copper wire；Wire 2 is provided with four, and uses copper material to make.
Use steel wire 7 to share stress when wire 2 is set up thus strengthen the tear-strength of cable body 1, in polychlorostyrene second
Alkene insulating barrier 3 is outside is provided with brass wire shielding net 8, cuts off the impact that wire is produced by the factors such as external electromagnetic, makes electric current transmit
More stable.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
