Abstract
The utility model provides a kind of flame retardant cable; the cable includes inner liner, inner protective layer, thermal insulation layer, barrier layer, fixed bed and external protection; four conductive core lines are fixed with the inner liner; conductive core line described in four is separated by two orthogonal copper sheets not to be contacted; silicone grease is filled with the cavity of the inner protective layer, asbestos are filled with the cavity of the thermal insulation layer.The utility model so as to be effectively increased the etch-proof feature of fireproofing of cable, and then improves the practicality of cable by using the anticorrosion of silicone grease and asbestos, fire prevention, the characteristic to insulate；Further by the design of sandwich construction, so that cable can better meet flame retardant effect under various circumstances.
Description
Technical field
The utility model relates generally to the technical field of cable, relates generally to a kind of flame retardant cable.
Technical background
Flame retardant cable, referring under regulation experimental condition, sample is burned, after experiment burning things which may cause a fire disaster is removed, the sprawling of flame
Only in the range of restriction, residual flame or it is residual burn in limiting time can self-extinguish cable.Characteristic is at all：In case of fire
It is possible to be burned and can not run, but the sprawling of the intensity of a fire can be prevented.Generally, electric wire can limit burning just in case catching fire
System does not produce sprawling in subrange, keeps other various equipment, avoids resulting in greater loss.
During cable routine use, when cable is in the condition of high temperature for a long time, the soft of cable can be caused
Change phenomenon, after cable softens, exospheric temperature is too high, will be delivered to the internal layer of cable, the conductive core line of internal layer is in length
Under the working condition of time, certain temperature can be produced, when the temperature that the temperature of conductive core line coordinates extraneous transmission to come in is mutual
With reference to when, the dieseling of cable can be caused.
On existing cable market, most cable realizes cable by changing the filler inside cable
The fire-retardant purpose of line, the cable of this structure are universal, and structure is single, it is impossible to better meet and cable is hindered at various temperature
The needs of combustion.
Based on this, it is necessary to develop it is a kind of complicated, disclosure satisfy that it is various in the case of, meet the cable of cable-flame retardant requirement
Line.
Utility model content
The utility model provides a kind of flame retardant cable, existing fire-retardant to solve what is proposed in above-mentioned technical background
Cable is not well positioned to meet under various circumstances, the technical problem of the purpose of cable-flame retardant.
The technical scheme in the invention for solving the above technical problem is：A kind of flame retardant cable, the cable include
Inner liner, inner protective layer, thermal insulation layer, barrier layer, fixed bed and external protection, four conductive cores are fixed with the inner liner
Line, the conductive core line described in four is separated by two orthogonal copper sheets not to be contacted, is filled out in the cavity of the inner protective layer
Filled with silicone grease, asbestos are filled with the cavity of the thermal insulation layer.
Described inner liner cavity is divided into four equal cavitys by the copper sheet, and the cavity described in four passes through glass
Fiber is filled.
Described asbestos are designed to cellular.
Polypropylene rope is filled with the cavity of the barrier layer external protection.
The fixed bed inner periphery is uniformly fixed with more iron wires.
Compared with prior art, the beneficial effects of the utility model are：
1. the utility model is by the structure design of multilayer, it is achieved thereby that in different environments, the fire-retardant mesh of cable
's；
2. further, the physical characteristic that the utility model is lost by the fire retardant anticorrosion of silicone grease and asbestos, so as to improve
The etch-proof characteristic of fireproofing of cable, and then add the practicality of the cable；
3. simultaneously, by being fixed with more iron wires between fixed bed and external protection, so as to add the table of the cable
Surface hardness, further increase the practicality of the cable.
Detailed explanation is carried out to the utility model below with reference to accompanying drawing and specific embodiment.

Embodiment
For the ease of understanding the utility model, the utility model is more comprehensively retouched below with reference to relevant drawings
State, some embodiments of the present utility model are given in accompanying drawing, but the utility model can be realized by different forms,
The embodiment described by text is not limited to, opposite, there is provided these embodiments are in order that to interior disclosed in the utility model
Hold more thorough and comprehensive.
Need to illustrate when, when element is referred to as " being fixedly arranged on " another element, it can be directly on another element
There may also be element placed in the middle, and when an element is considered as " connection " another element, it can be directly to separately
One element may be simultaneously present centering elements, term as used herein " vertically ", " horizontal ", "left", "right"
And similar statement is for illustrative purposes only.
Unless otherwise defined, all of technologies and scientific terms used here by the article is led with belonging to technology of the present utility model
The implication that the technical staff in domain generally connects is identical, is in term knowledge used in the description of the present utility model herein
The purpose of description specific embodiment, it is not intended that in limitation the utility model, term as used herein " and/or " include
The arbitrary and all combination of one or more related Listed Items.
Accompanying drawing 1, a kind of flame retardant cable are refer to, the cable includes inner liner 1, inner protective layer 4, thermal insulation layer 5, barrier layer
6th, fixed bed 7 and external protection 9, four conductive core lines 2 are fixed with the inner liner 1, the conductive core line 2 described in four passes through
Two orthogonal copper sheets 3 are separated and not contacted, and silicone grease, the sky of the thermal insulation layer 5 are filled with the cavity of the inner protective layer 4
Intracavitary is filled with asbestos.
The utility model is by the structure design of multilayer, it is achieved thereby that in different environments, the fire-retardant purpose of cable；
