Description

A kind of flame retardant type low smoke and zero halogen industry high temperature-resistant cable

Technical field

This utility model relates to field of cables, particularly relates to a kind of flame retardant type low smoke and zero halogen high temperature resistant electricity of industry Cable.

Background technology

At present, cable is widely used in the field such as electric power, communications, along with constantly sending out of science and technology Exhibition, cable suffers from being widely applied in every field, but the cable used in industry now, Because the design of its structure is unreasonable, can not meet the needs of present people, some cables are shorter for service life, And not there is good stretch-proof performance, when a fire, cable can not bear high temperature, causes The situation of cable bad, and when cable fire, common cable, because of material problem, can produce substantial amounts of Harmful gas, thus exacerbate fire to life and the destruction of property.

Utility model content

In order to overcome the defect of above-mentioned prior art, it is low that the purpose of this utility model is to provide a kind of flame retardant type Cigarette Halogen industry high temperature-resistant cable.

This utility model takes techniques below scheme to realize: a kind of flame retardant type low smoke and zero halogen industry is resistance to High-temperature cable, it includes that cable body, described cable body include conductor, insulating barrier, protective layer and outer Sheath, described cable body is internally provided with isolation mount；And described cable body is internally provided with multiple Conductor；Described conductor outer wrapping layer protective layer；Described conductor and protective layer extrude composition cable core jointly； Described cable body is internally provided with multiple cable core；Described cable core and isolation mount are tangent；Outside described cable core One layer insulating is set；One layer of back-fire relief belt is extruded outside described insulating barrier；One is extruded outside described back-fire relief belt Layers of polyethylene enhancement Layer；One layer of oxygen barrier layer is extruded outside described polyethylene enhancement Layer；Extrude outside described oxygen barrier layer One layer of oversheath.

Above-mentioned a kind of flame retardant type low smoke and zero halogen industry high temperature-resistant cable, described conductor is multiply nickel plating copper wire Stranded form.

Above-mentioned a kind of flame retardant type low smoke and zero halogen industry high temperature-resistant cable, described isolation mount cross section is " ten " character form structure.

Above-mentioned a kind of flame retardant type low smoke and zero halogen industry high temperature-resistant cable, described polyethylene enhancement Layer inner loop Around being provided with many metal knitted bars.

Above-mentioned a kind of flame retardant type low smoke and zero halogen industry high temperature-resistant cable, described oxygen barrier layer is polyolefin oxygen barrier Material is made.

Above-mentioned a kind of flame retardant type low smoke and zero halogen industry high temperature-resistant cable, described oversheath uses butyronitrile polychlorostyrene Vinyl material is made.

In sum this utility model have the advantages that this utility model have reasonable in design, High temperature resistant and service life the advantage such as length, described oversheath uses butyronitrile pvc material to make, thus Ensure that cable has resistant to elevated temperatures effect, and enable cable to use under the rugged environments such as oil immersion, Prevent the cracking situation causing cable short circuit in cable body surface, extend the use longevity of cable body Life.

Wherein: 1, cable body；2, isolation mount；3, conductor；4, protective layer；5, insulating barrier； 6, back-fire relief belt；7, polyethylene enhancement Layer；8, metal knitted bar；9, oxygen barrier layer；10, oversheath.

Detailed description of the invention

As it is shown in figure 1, a kind of flame retardant type low smoke and zero halogen industry high temperature-resistant cable, it includes cable body 1, Described cable body 1 includes conductor 3, insulating barrier 5, protective layer 4 and oversheath 10, described cable body 1 is internally provided with isolation mount 2；And described cable body 1 is internally provided with multiple conductor 3；Described lead Body 3 outer wrapping layer protective layer 4；Described conductor 3 and protective layer 4 extrude composition cable core jointly；Described electricity Cable body 1 is internally provided with multiple cable core；Described cable core and isolation mount 2 are tangent；Described cable core peripheral hardware Put a layer insulating 5；One layer of back-fire relief belt 6 is extruded outside described insulating barrier 5；Described back-fire relief belt 6 is outer to be squeezed Bag layer of polyethylene enhancement Layer 7；One layer of oxygen barrier layer 9 is extruded outside described polyethylene enhancement Layer 7；Described oxygen barrier One layer of oversheath 10 is extruded outside layer 9.

Described conductor 3 closes for multiply nickel-clad copper skein silk and forms, and described nickel plating copper wire has good anticorrosive Property, and bigger electric current can be carried, there is the features such as high temperature resistant and antioxidation；Described cable body 1 The internal isolation mount 2 arranged can make cable body 1 internal structure the compactest, is separated by conductor 3, Prevent conductor 3 from the situation of skew occurring so that it is more stable in work process；Described back-fire relief belt has Outstanding heat resistance, does not haves the situation of deformation the most yet, has good crushing resistance Energy；Described polyethylene enhancement Layer 7 increases the resistance to tension of cable body 1, it is to avoid in cable body 1 There is situation about rupturing because of local pressure in portion's structure, and makes the cable body 1 can be at the most severe ring Work under border；Described metal knitted bar 8 improves the capacity of resisting disturbance of cable body 1, thus also improves The reliability of cable body 1 signal transmission；Described oxygen barrier layer 9 is made for polyolefin oxygen barrier material, tool There are good processing characteristics, excellent insulating properties, will not discharge environmentally harmful in high temperature environments Material；Described oversheath 10 uses butyronitrile pvc material to make such that it is able to ensure that cable has resistance to The effect of high temperature, and enable cable to use under the rugged environments such as oil immersion, prevent cable body 1 table The cracking situation causing cable short circuit in face, extends the service life of cable body 1.

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