Description
Technical field
This utility model is related to electric power transport field, specially a kind of anti-flammability power cable.
Background technology
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 difference occasions.But most of cable typically exists
Wire outer surface covers one layer of plastic layer, easily damaged and aging, and layer of structure arrangement is unreasonable, between layers not
Compact, conductor shape is more single, and packed layer is not solid firmly, and filling effect is not good, and restrictive coating is fragile, integrally uses the longevity
Life is shorter.
Content of the invention
The purpose of this utility model is to provide a kind of anti-flammability power cable, to solve proposition in above-mentioned background technology
Problem.
For achieving the above object, this utility model provides following technical scheme：A kind of anti-flammability power cable, including cable
Body, hollow seated tube, wire stylet, the first protective jacket, the second protective jacket, flame-retardant layer and exoperidium, described cable body center
It is provided with hollow seated tube；It is provided with outside described hollow seated tube outside wire stylet described in wire stylet and be provided with the first protection
Set；It is provided with packed layer between described hollow seated tube and the second protective jacket；It is provided with flame-retardant layer outside described second protective jacket；Institute
State and outside flame-retardant layer, be provided with exoperidium.
Preferably, the mouth of pipe section of described hollow seated tube is in pentalpha, and middle part hollow out.
Preferably, described packed layer adopts composite material of silicon carbide to fill.
Preferably, described first protective jacket and the second protective jacket are all made using polychloroethylene insulation material.
Preferably, flame-retardant layer is made using halogen-free and low-smoke flame-retardant polyolefin material.
Compared with prior art, the beneficial effects of the utility model are：This utility model adopts hollow seated tube by wire
Positioning, prevents from misplacing, and middle part engraved structure can play thermolysis；Polyvinyl chloride insulation layer wraps up wire, and radiating is absolutely
Edge performance is fabulous, so that electric current is transmitted more stable, and flame-retardant layer is halogen-free and low-smoke flame-retardant polyolefin layer, intercepts external heat source to wire
Impact.
Brief description
Fig. 1 is this utility model sectional view.
In reference：1- cable body；2- hollow seated tube；3- wire stylet；4- first protective jacket；5- second protects
Set；6- flame-retardant layer；7- exoperidium；8- packed layer.
Specific embodiment
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 description is 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 the premise of making creative work
The every other embodiment being 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 anti-flammability power cable, including cable body 1, hollow seated tube 2, wire stylet 3, the first protective jacket 4, second
Protective jacket 5, flame-retardant layer 6 and exoperidium 7, cable body 1 is provided centrally with hollow seated tube 2；It is provided with outside hollow seated tube 2
Wire stylet 3；It is provided with the first protective jacket 4 outside wire stylet 3；It is provided with packed layer 8 between hollow seated tube 2 and the second protective jacket 5；
It is provided with flame-retardant layer 6 outside second protective jacket 5；It is provided with exoperidium 7 outside flame-retardant layer 6.
The mouth of pipe section of hollow seated tube 2 is in pentalpha, and middle part hollow out, can fix the position of wire stylet 3, and can
To play thermolysis；Packed layer 8 adopts composite material of silicon carbide to fill；First protective jacket 4 and the second protective jacket 5 are all using poly-
Vinyl chloride insulant is made, insulation effect and good flame retardation effect；Flame-retardant layer 6 adopts halogen-free and low-smoke flame-retardant polyolefin material system
Become, enhance fire resistance.
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, this practicality can be realized in other specific forms new
