Description

A kind of flexibility corrosion proof cable

Technical field

The utility model relates to field of cable technology more particularly to a kind of flexible corrosion proof cables.

Background technique

With the development that science and technology is with rapid changepl. never-ending changes and improvements, cable plays an important role in modern metropolitan cities and industrial building, certainly Requirement to cable is also higher and higher, and the cable that many industrial parks are laid with is chronically in moist and acid-base property environment, makes Cable be easy to is destroyed and is corroded, shorten the service life of cable, there are also be exactly in human activity and industrial production very It is easy to happen fire condition, once catching fire, cable will blaze up quickly, be unable to maintain that the power supply of a period of time, cause each The paralysis immediately of a system largely can bring many difficulties.It is therefore proposed that a kind of flexibility corrosion proof cable.

Utility model content

Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of flexibility proposed is corrosion-resistant Cable.

To achieve the goals above, the utility model adopts the technical scheme that

A kind of flexible corrosion proof cable is designed, including more cable cores, the more cable cores contact with each other and outside each cable cores Side is enclosed with wrapper, and binding layer is provided on the outside of the more cable cores, and bundlees layer and more cable cores are tightly bundled in one It rises, and contacts with each other with wrapper, anti-interference layer is provided on the outside of the wrapper, and anti-interference layer is not contacted with binding layer, And there are gap, the anti-interference layer outside is enclosed with insulating layer, is enclosed with anti-corrosion layer, the corrosion resistant on the outside of the insulating layer It is enclosed with fireprotection layer on the outside of erosion layer, is enclosed with oversheath on the outside of the fireprotection layer.

Preferably, glass fibre, and glass everywhere in gap are filled in the gap between the anti-interference layer and binding layer Glass fibre packing density is consistent.

Preferably, the cable core is that the core material of naked copper is twisted.

Preferably, the oversheath is specially polychloroprene polymer material, and the fireprotection layer is specially polytetrafluoroethylene (PTFE) macromolecule, The anti-corrosion layer is specially polyester, and thickness should be greater than 20 microns.

The utility model proposes a kind of flexible corrosion proof cable, beneficial effect is: the flexibility corrosion proof cable has Corrosion-resistant, fire-retardant advantage can work under the extreme environment of Various Complex, can fine ground resistance using polytetrafluoroethylene (PTFE) Combustion, and polyester material is corrosion-resistant, substantially prolongs the service life of cable.The conductor is that bare copper wire core material is twisted, Its cross sectional shape is round or sector structure, not only substantially increases the working efficiency of cable, also makes its work more stable, and The conductor structure is easy to process, and production length is unrestricted, with certain flexibility and bendability when use, facilitates worker Laying.

Detailed description of the invention

Fig. 1 be the utility model proposes a kind of flexible corrosion proof cable structural schematic diagram.

In figure: binding layer 1, glass fibre 2, cable core 3, wrapper 4, anti-interference layer 5, insulating layer 6, anti-corrosion layer 7, fire prevention Layer 8, oversheath 9.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1, a kind of flexible corrosion proof cable, including more cable cores 3, cable core 3 be the core material of naked copper it is twisted and At the cross sectional shape of cable core 3 is round or sector structure, not only substantially increases the working efficiency of cable, also makes its work more Add stabilization.

More cable cores 3 contact with each other and 3 outside of each cable core is enclosed with wrapper 4, are provided with bundle on the outside of more cable cores 3 Layer 1 is tied up, and bundlees layer 1 and tightly bundles more cable cores 3, and contact with each other with wrapper 4, is arranged on the outside of wrapper 4 There is anti-interference layer 5, and anti-interference layer 5 is not contacted with binding layer 1, and there are gaps, the sky between anti-interference layer 5 and binding layer 1 Glass fibre 2 is filled in gap, and 2 packed density of glass fibre is consistent everywhere in gap.Wrapper 4 separates more cable cores 3 It opens to avoid contacting with each other, causes to generate safety problem, more cable cores 3 are closely bundled by binding layer 1, avoid dispersing, first It can reduce the cross-sectional area of cable, second is also easy to control when producing and processing, and prevents 3 length of cable core in a certain section of cable It is inconsistent.

It is enclosed with insulating layer 6 on the outside of anti-interference layer 5, anti-corrosion layer 7 is enclosed on the outside of insulating layer 6, is wrapped on the outside of anti-corrosion layer 7 It is wrapped with fireprotection layer 8, oversheath 9 is enclosed on the outside of fireprotection layer 8, oversheath 9 is specially polychloroprene polymer material, and fireprotection layer 8 is specially Polytetrafluoroethylene (PTFE) high molecular material, anti-corrosion layer 7 is specially polyester, and thickness should be greater than 20 microns.Oversheath 9 is first yes Cable is protected from pressure, and external pressure is avoided to damage cable, and anti-corrosion layer then prevents the substance in environment to cable It causes to corrode, influences the working effect of cable, fireprotection layer then guarantees that fire occurs for circuit surface when breaking down.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
