There is inner rubber layer, the outer wall package of the inner rubber layer is provided with flame-retardant textile layer, and the outer wall package of the flame-retardant textile layer is set
It is equipped with outer rubber layer.
Preferably, the inner rubber layer is set as neoprene flame retardant rubber layer, the thickness of neoprene flame retardant rubber layer
It is set as three millimeters.
Preferably, the outer wall surface even application of the outer rubber layer is provided with flame-retardant coating layer, and flame-retardant coating layer is set
It is set to cable fire-refractory coating.
Preferably, the flame-retardant textile layer is set as heat-resistance and flame-retardant fiber layer.
Preferably, the inner cable layer includes conductor shield, and the outer wall package of conductor shield is provided with insulating layer.
Compared with prior art, the utility model has the beneficial effects that
Security against fire high fire-retardance fireproof power cable, structure is simple, easy to use, is provided with flame-retardant textile layer, resistance
Combustible fabric layer is heat-resistance and flame-retardant fiber layer, flame-retardant textile layer contact flame or when red-hot object can prevent from being ignited in itself,
Delay and terminate burning, while being provided with inner rubber layer, inner rubber layer is neoprene flame retardant rubber layer, good flame retardation effect weight
Gently, while being provided with asbestos fibre layer, asbestos are good fire proofings, and price is low, light-weight, by flame-retardant textile layer,
Inner rubber layer and asbestos fibre layer achieve the effect that flame-retardant, simultaneously because flame-retardant textile layer, inner rubber layer and asbestos fibre
The material of layer lighter in weight uniform in material, will not excessively increase the weight of cable.
Detailed description of the invention
Fig. 1 are as follows: the utility model structure diagram.
In figure: 1, conductor；2, inner cable layer；3, asbestos fibre layer；4, inner rubber layer；5, flame-retardant textile layer；6, outer rubber
Layer.
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；In order to better illustrate this embodiment, attached
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.
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.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of security against fire high fire-retardance fire resistant electric power electricity
Cable, including conductor 1, the external package of conductor 1 are provided with inner cable layer 2, and the outer wall package of inner cable layer 2 is provided with asbestos fibre
Layer 3, the outer wall package of asbestos fibre layer 3 are provided with inner rubber layer 4, and the outer wall package of inner rubber layer 4 is provided with inner rubber layer 4,
The outer wall package of inner rubber layer 4 is provided with flame-retardant textile layer 5, and the outer wall package of flame-retardant textile layer 5 is provided with outer rubber layer 6.
Wherein: inner rubber layer 4 is set as neoprene flame retardant rubber layer, and neoprene flame retardant rubber is a kind of flame retardant effect
Good light-weight rubber flame-retarded material, the thickness of neoprene flame retardant rubber layer are set as three millimeters, avoid neoprene fire-retardant
