Technical field
The utility model relates to a kind of cables, and in particular to a kind of flexible flame-retardant cable.
Background technique
With the development of national economy and the progress of technology, the application field and range of cable are more and more wider, comprehensive to cable
The requirement for closing performance is also higher and higher, for example, in some cases, both having required cable flexibility with higher, and also cable having been required to have
There are higher tensile strength, stronger anti-flammability, water preventing ability etc..In the prior art, meet flexibility requirements be then difficult to meet it is anti-
It stretches and requires, meet flame-retardancy requirements and be then difficult to meet water preventing ability requirement.
Utility model content
The utility model based on the above background, to solve the problems, such as be：Design it is a kind of flexibility, stretch-proof, it is fire-retardant, block water
Etc. with comprehensive advantage flexible flame-retardant cable.
The utility model is achieved by the following technical solution：A kind of flexible flame-retardant cable, including：Center strengthening core,
Conductor, flame-retardant layer, sheath, it is characterised in that：There is special-shaped packing outside the center strengthening core, around the abnormity packing
Even to be provided with multiple concave rings, the conductor is set in concave ring, and the flame-retardant layer is coated on around special-shaped packing, described fire-retardant
Layer is coated with heat-conducting layer, and the sheath is coated on outside heat-conducting layer, is equipped with more elastic strips in the flame-retardant layer, the conductor by
More copper wires are twisted, and added with water-proofing powder between the copper wire, are successively coated with glass fibers from inside to outside around the conductor
Layer, insulating layer, copper strip shielding layer are tieed up, the center strengthening core uses aramid fiber material, and the flame-retardant layer is the low cigarette of soft type
Halogen-free flameproof elastic material.
Further, the insulating layer uses warm water crosslinking polythene material.
Further, the heat-conducting layer is nano aluminium oxide/LDPE Composite.
Further, the elastic strip section is circle.
Further, the sheath uses polyamide material.
Compared with prior art, the utility model has the advantages that：
1, it is provided with center strengthening core, and the radial direction of cable had both been improved as core material is reinforced using aramid fiber
Stretching resistance and bending resistance, it is ensured that it is flexible.
2, the design of special-shaped packing, keeps the construction of cable more stable, also plays a very good protection to cable core, avoid
Cable core is pressurized.
3, there is water-proofing powder between conductor copper wire, effectively water can be prevented to enter conductor from end, improve the safety of cable
Property.
4, the design of elastic strip, increases the toughness of cable, and when bending is not easily broken, while there are also shock-absorbing functions.
5, using nano aluminium oxide/LDPE Composite as heat-conducting layer, thermal coefficient is high, heating conduction
It is good, extend the service life of cable.
6, sheath uses polyamide material, increases cable surface hardness and smoothness, termite-proof sting can be effectively prevent to bite.
7, flame-retardant layer uses soft low-smoke halogen-free flame-retardant elastic material, has both played fire-retardant effect, and ensure that electricity
