Description
Technical field
It the utility model is related to field of cable technology, more particularly to a kind of water proof fire retardant composite cable.
Background technology
With being showing improvement or progress day by day for modern science and technology, cable with its features such as simple in construction, technique is easily realized, cost is low it is extensive
Using, each core parcel insulating barrier inside existing cable, then wrapped belting layer forms a cable, each core when wrapped
Between easy play, and lack gauze screen between each core, easily form interference；In addition, existing cable-flame retardant and fire line
Can be poor, lack the market competitiveness.
Utility model content
In view of the shortcomings of the prior art, the utility model, which is provided between a kind of structural strength height, internal each core, has screen
Cover the waterproof fire-retardant composite cable of function.
Technical scheme is used by the utility model solves its technical problem：The water proof fire retardant composite cable include by
It is interior to comprise at least three lines to the cable core being sequentially provided with outside, belting layer, inner liner, waterstop, flame retardant bed and sheath, the cable core
Core, the every core outsourcing insulating layer coating, isolating bar is provided between the core, the isolating bar is in star-like strip knot
Structure, is provided with the gauze screen of braiding in it, the gauze screen is consistent with the shape of the isolating bar.
In a kind of preferred embodiment of water proof fire retardant composite cable provided by the utility model, the cable core and belting layer
Between fill water blocking yarn.
In a kind of preferred embodiment of water proof fire retardant composite cable provided by the utility model, the inner liner is using crowded
Wrap molding.
In a kind of preferred embodiment of water proof fire retardant composite cable provided by the utility model, the insulating barrier and sheath
It is that high density polyethylene (HDPE) is wrapped to form.
Compared with prior art, the beneficial effect of water proof fire retardant composite cable provided by the utility model is：
First, the utility model isolates core by the isolating bar, not only prevent the play when wrapped, also improves
Structural strength, and be provided with gauze screen in the isolating bar, individual each line can be avoided to being shielded well between each core
Interference between core, while also there is good insulating effect, avoid somewhere damage and caused by short circuit；
2nd, the flame retardant bed being provided with the sheath, there are good Fire resistances, improves the fire resistance of cable；
3rd, the water blocking yarn filled between the waterstop and the cable core and belting layer that are provided with the flame retardant bed, has
Preferable water resistance, avoid short circuit caused by infiltration water enters.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Other accompanying drawings are obtained, wherein：
Fig. 1 is the structural representation of water proof fire retardant composite cable provided by the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only part of the embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The all other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the water proof fire retardant composite cable 1 include be sequentially provided with from the inside to the outside cable core 11, belting layer 12,
Inner liner 13, waterstop 14, flame retardant bed 15 and sheath 16, the cable core 11 comprise at least three cores 112, the every core
112 outsourcing insulating layer coatings 1120, isolating bar 17 is provided between the core 112, the isolating bar 17 is in star-like list structure,
The gauze screen 172 of braiding is provided with it, the gauze screen 172 is consistent with the shape of the isolating bar 17.
Preferably, water blocking yarn 18 is filled between the cable core 11 and belting layer 12.
Preferably, the inner liner 13 uses and extrudes shaping.
Preferably, to be that high density polyethylene (HDPE) is wrapped form for the insulating barrier 1120 and sheath 16.
The beneficial effect of water proof fire retardant composite cable 1 provided by the utility model is：
First, the utility model isolates core 112 by the isolating bar 17, not only prevent the play when wrapped,
Also improve structural strength, and gauze screen 172 be provided with the isolating bar 17, can to being shielded well between each core,
Avoid the interference between each core, while also there is good insulating effect, avoid somewhere damage and caused by it is short-circuit；
2nd, the flame retardant bed 15 being provided with the sheath 16, there are good Fire resistances, improves the fire resistance of cable；
That is filled between the waterstop 14 and the cable core 11 and belting layer 12 that the 3, are provided with the flame retardant bed 15 blocks water
Yarn 18, there is preferable water resistance, avoid short circuit caused by infiltration water enters.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
