Description
Technical field
The invention belongs to power cable technical fields, and in particular to a kind of rail traffic fire resisting stretch-proof power cable.
Background technique
With the development of modernization rail traffic, total kilometrage is increasingly longer, it is increasingly wider to be related to territory, F-Zero is more next
Faster, the technical problem and built environment faced also becomes increasingly complex, as the Transit Equipment of electric power energy supply, power supply electricity
The superiority and inferiority of cable is directly related to the transport capacity and safety of Transit Equipment, such cable early investment is big, once investment fortune
After battalion breaks down, it is difficult discovering and ruling out at the first time, so as to cause the expansion of failure, and then influences high-speed rail transportation
The running of equipment power supply system, and the anti-interference of cable, insulating properties, fire resistance, stretch-resistance etc. can all influence rail traffic
The operation of equipment, wherein very good solution had been obtained for anti-interference and insulating properties at present, and fire resistance and tension
Performance still seriously restricts the development of rail traffic.
Summary of the invention
In view of the deficienciess of the prior art, the present invention provides a kind of safe and reliable rail traffic fire resisting stretch-proof
Power cable.
The present invention is achieved by the following technical solutions：
A kind of rail traffic fire resisting stretch-proof power cable, including three electric conductors, the electric conductor outside are enclosed with
Conductor shielding, the conductor shielding outside are enclosed with insulating layer, and insulation shielding, the insulation screen are enclosed on the outside of the insulating layer
Cover outside and be enclosed with inner sheath, on the outside of the inner sheath between accompany supporting body, there are three the carrying outside is uniformly opened
Card slot is respectively embedded into the inner sheath in the card slot, is filled with filled layer, the filling on the outside of the supporting body and inner sheath
Layer outside is enclosed with liner layer, and the liner layer outer surface is brushed with coating for EMI shielding, package on the outside of the coating for EMI shielding
There is carbon fibre web, flame retardant coating is enclosed on the outside of the carbon fibre web, is enclosed with oversheath on the outside of the flame retardant coating.
The supporting body uses ethylene chlorotrifluoroethylene.
The carbon fibre web is woven by asphalt base carbon fiber.
The inner sheath and liner layer use crosslinked polyethylene.
The oversheath uses low-smoke halide-free fireproof composite polyolefine material.
Compared with prior art, the beneficial effects of the invention are as follows：
1, in the present invention, on the one hand the card slot design of supporting body avoids electric conductor torque failure, on the other hand, ethylene trifluoro
Vinyl chloride copolymer has outstanding tensile property, increases the stability and safety of structure, in addition, ethylene chlorotrifluoroethylene is total
Polymers will not catch fire, and can prevent flame spread；
2, Carbon fibe net is woven by asphalt base carbon fiber, and the 1/4 of quality specific gravity deficiency steel, but tensile strength, tension
Elasticity modulus is much higher than steel, while greatly improving the tensile property of cable, cost control easy to produce；
3, each electric conductor in the present invention is enclosed with conductor shielding, insulation, insulation shielding, and outside, which is also brushed, electromagnetism
Curtain coating, whole strong antijamming capability promote the security performance of cable.

Specific embodiment
Such as a kind of Figure of description rail traffic fire resisting stretch-proof power cable shown in FIG. 1, including three electric conductors
1, conductor shielding 2 is enclosed on the outside of electric conductor 1, and insulating layer 3 is enclosed on the outside of conductor shielding 2, insulation is enclosed on the outside of insulating layer 3
4 are shielded, inner sheath 5 is enclosed on the outside of insulation shielding 4, inner sheath accompanies supporting body 6 between 5 outside, and 6 lateral surface of supporting body is uniform
It opens there are three card slot 7, card slot 7 wraps up the lateral surface of half inner sheath 5, it is filled with filled layer 8 on the outside of supporting body 6 and inner sheath 5,
Liner layer 9 is enclosed on the outside of filled layer 8,9 outer surface of liner layer is brushed with coating for EMI shielding 10, wraps on the outside of coating for EMI shielding 10
It is wrapped with carbon fibre web 11, flame retardant coating 12 is enclosed on the outside of carbon fibre web 11, oversheath 13 is enclosed on the outside of flame retardant coating 12.
Preferably, supporting body 6 uses ethylene chlorotrifluoroethylene, insulating properties, intensity, wearability, creep resistance
Common plastics can be much higher than, ethylene chlorotrifluoroethylene dielectric constant is low, in addition, ethylene chlorotrifluoroethylene is not
It can catch fire, flame spread can be prevented.
Preferably, carbon fibre web 11 is woven by asphalt base carbon fiber, and the 1/4 of asphalt base carbon fiber specific gravity deficiency steel,
But tensile strength is 7~9 times of steel, and elasticity modulus is 230~430GPa, is also much higher than steel, the asphaltic base carbon fiber used here
