It is insoluble not melt.
With the development of automobile industry, to being gradually increased for the heat resistant type of cable, safety and environmental requirement, meanwhile, with
Enriching constantly for automobile function, demand of the car electrics to electric energy is more and more, and this requires in same cross-sectional and weight
On the basis of, the higher the better for the current-carrying capacity of cable.And crosslinked polyolefin materials have good heat resistance and resistant to liquid and good because of it
Good mechanical performance above has good prospect in the application of automobile batteries cable.Crosslinking polyolefin insulated cable substitution passes
The PVC insulated cable of system, has good market prospects.
With the raising that automotive performance and comfort require, the increase of electric function, in automobile modern designs, harness can
It is being reduced with space, this heat dissipation that will lead to the space of automobile wiring beam becomes the problem of paying close attention to, this inevitable requirement automobile uses
The necessary high temperature resistant of electric wire simultaneously has reliable safety, and conventional PVC insulated electric conductor is no longer satisfied these requirements, heat-resisting etc.
The higher cable product exploitation of grade uses the trend that should also become a certainty.Secondly, the protection with modern humans to environment
To realize more and more stronger, the material for polluting environment is inevitable gradually replaced cleaning material, and PVC is a kind of material for polluting environment,
Therefore it should gradually be replaced by other free of contamination materials, crosslinked polyolefin materials can meet the requirement of the above harshness.
Traditional cross-linking radiation polyolefin meets heat resistance and mechanical performance, but fire retardant is halogen, not environmentally,
A large amount of irritation toxic gas can be generated after electric wire burning.Another is being met to reach and being not filled with halogen-free flame retardants
Under conditions of anti-flammability, mechanical performance is often had lost.Automobile electric wire is adjoint on the complex road surfaces such as moving, jolting, collide
The activity of vehicle has very high requirement to mechanical performance, and the mechanical performance after electric wire aging also hardly becomes
Change can be only achieved vehicle requirement.
Summary of the invention
In order to solve the above technical problems, the utility model provides a kind of irradiation crosslinking halogen-free fire retardant polyolefin cable.
The utility model, including multiple conducting wires and insulating layer, portion, insulating layer are wrapped in the cable for multiple conducting wires setting
Outside multiple conducting wires, each conducting wire by 1 single line using twisted wire center line as axis, be layered it is orderly be stranded in around it, phase
It is contrary or twisted in the same direction to face conducting wire twisted layer, insulating layer uses irradiation crosslinking halogen-free flame retardant polyolefine material.
The insulating layer minimum thickness is 0.28 ~ 0.39mm.
The sectional area of wire is 0.205 ~ 0.723mm2.
The lead material is naked copper or tinned stranded wire.
Compared with prior art the utility model has the following beneficial effects:
The utility model is designed reasonably, it is easy to use, it is higher than traditional at least 10 DEG C of temperature resistant grade of electric wire, does not need electric wire
The levels of upgrading material can meet the daily demand of electric system, reduce use cost, have anti-flammability and cable is not
Containing halogen, toxic gas will not be discharged after electric wire burning, makes vehicle that there is reliable mechanical performance in defined service life.
