Description

The anti-fracture cable of a kind of low smoke and zero halogen armouring

Technical field

The utility model relates to field of cables, particularly relates to the anti-fracture cable of a kind of low smoke and zero halogen armouring.

Background technology

At present, along with the development of science and technology, the fields such as industry are also at rapid advances, what bring is the increase of cable consumption thereupon, cable normally has several or several groups of wires often to organize the cable of at least two stranded similar ropes, often organize mutually insulated between wire, and be often twisted into around a center, whole outside is surrounded by the cover layer of high-insulation, the kind of cable has a lot, the environment for use that can be applied in fields different in a lot of field is different, therefore different requirements is also had to cable, but existing cable can not play anti-fracture effect because its structural design is unreasonable, the situation occurring fracture is easy to when cable bears larger pressure, bring very large inconvenience.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide the anti-fracture cable of a kind of low smoke and zero halogen armouring.

The utility model is taked following technical scheme to realize: the anti-fracture cable of a kind of low smoke and zero halogen armouring, and it comprises cable body, and described cable body comprises conductor, insulating barrier, screen and oversheath, and described cable body cross section is circular configuration; Described cable body inside is provided with multiple conductor; Described conductor be outside equipped with many packings and conductor tangent; One deck insulating barrier is set outside described conductor; Described insulating barrier, between conductor and packing, gap portion is provided with filler; One deck screen is extruded outside described insulating barrier; Layer of metal sheath is extruded outside described screen; One deck reinforced layer is extruded outside described metallic sheath; One deck belting layer is extruded outside described reinforced layer; One deck oversheath is extruded outside described belting layer.

The above-mentioned anti-fracture cable of a kind of low smoke and zero halogen armouring, described conductor adopts real core copper core or multiply to press copper core and makes.

The above-mentioned anti-fracture cable of a kind of low smoke and zero halogen armouring, described insulating barrier inside is provided with many carbon fiber composite core rods.

The above-mentioned anti-fracture cable of a kind of low smoke and zero halogen armouring, described belting layer is that double-sided insulation waterstop material is made.

The above-mentioned anti-fracture cable of a kind of low smoke and zero halogen armouring, described reinforced layer is that pvc material is made.

The above-mentioned anti-fracture cable of a kind of low smoke and zero halogen armouring, described oversheath is that chloroprene rubber material is formed.

The utility model has following beneficial effect in sum: the utility model has the advantages such as reasonable in design, anti-fracture and long service life, described belting layer adopts double-sided insulation waterstop to make, cable energy undergoes rapid expansion when humidity can be made, guarantee that moisture can not enter cable body inside, and make cable body structure more rounding.

Accompanying drawing explanation

Fig. 1 is the utility model cross-sectional structure schematic diagram;

Wherein: 1, cable body; 2, conductor; 3, packing; 4, filler; 5, insulating barrier; 6, carbon fiber composite core rod; 7, screen; 8, metallic sheath; 9, reinforced layer; 10, belting layer; 11, oversheath.

Embodiment

As shown in Figure 1, the anti-fracture cable of a kind of low smoke and zero halogen armouring, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 5, screen 7 and oversheath 11, and described cable body 1 cross section is circular configuration; Described cable body 1 inside is provided with multiple conductor 2; It is tangent with conductor 2 that described conductor 2 is outside equipped with many packings 3; Outside described conductor 2, one deck insulating barrier 5 is set; Described insulating barrier 5, between conductor 2 and packing 3, gap portion is provided with filler 4; One deck screen 7 is extruded outside described insulating barrier 5; Layer of metal sheath 8 is extruded outside described screen 7; One deck reinforced layer 9 is extruded outside described metallic sheath 8; One deck belting layer 10 is extruded outside described reinforced layer 9; One deck oversheath 11 is extruded outside described belting layer 10.

Described conductor 2 adopts real core copper core or multiply to press copper core and makes, and conductor 2 signal transmission not only can be made more stable, and be not easy to fracture, also be convenient to the maintenance of later stage workman; Described packing 3 and filler 4 make cable body 1 internal structure more compact, effectively prevent conductor 2 from occurring the situation of skew, and improve the bending resistance of cable body 1; Described insulating barrier 5 effectively raises the insulation property of cable; Described carbon fiber composite core rod 6 improves the tensile strength of cable body 1, and lighter in weight, effective protection cable body 1; Described screen 7 improves the antijamming capability of cable body 1, prevents outer signals from impacting cable, makes its course of work more stable; Described metallic sheath 8 effectively can ensure that cable can stand extraneous powerful destructive power, makes cable be isolated from the outside simultaneously, reduces the danger coefficient of fire; Described reinforced layer 9 is made for pvc material, not only serves the effect making cable body 1 built-in electrical insulation, and effectively raises the tensile strength of cable, make cable more solid; Described belting layer 10 adopts double-sided insulation waterstop to make, and can make cable energy undergoes rapid expansion when humidity, guarantee that moisture can not enter cable body 1 inner, and make cable body 1 structure more rounding; Described oversheath 11 adopts neoprene to make, and also can not discharge environmentally harmful gas, reduce the harm of fire to a certain extent, protect the life and health of people under cable generation combustion case.

The above is embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
