Good fire performance and flame-retarding characteristic, cable remains able to continued power for a period of time during fire, and cable is nonflammable, and can hinder
The only expansion spread with disaster of flame, while by the oxygen barrier layer of setting, making it be free of halogen, smoke amount is small, is conducive to people
Member's escape, and environment protection, rat ant proof repellant is added in oversheath, so that rat-and-ant proof purpose is reached, while will not be to ring
Border is damaged, and security performance is high, using full-featured.
To achieve the above object, the utility model provides following technical scheme：A kind of high-performance subway cable, including lead
Body, the conductor is wrapped with insulating barrier, and the periphery of insulating barrier is arranged with inner liner, is set between the inner liner and insulating barrier
Be equipped with flame-retardant filler, and inner liner is externally provided with waterproof layer, the periphery of the waterproof layer is enclosed with oversheath, and waterproof layer with it is outer
Armor and oxygen barrier layer are provided between sheath, the armor is arranged on the periphery of oxygen barrier layer.
It is preferred that, the conductor is made up of TU1 copper, aluminum or aluminum alloy material members.
It is preferred that, the insulating barrier is made up of ceramic polyolefin layers component.
It is preferred that, the inner liner is overlapping wrapped using two layers of high fire-retardance alkali-free glass fiber band, and Duplication is 20%.
It is preferred that, the waterproof layer is continuously to indulge bag using plastic-aluminum waterproof composite band, and seam connection carries out sweat soldering.
It is preferred that, the oxygen barrier layer is made up of high flame resistance, low smoke halogen-free polyolefin material layer component.
It is preferred that, the armor is made up of brass band material members, and thickness is 0.12mm, and Duplication is 15%.
It is preferred that, the oversheath is by termite-resistant rodent-resistant repellant UV resistant low-smoke halide-free fireproof composite polyolefine material layer structure
Part is made.
Compared with prior art, the beneficial effects of the utility model are：The utility model is reasonable in design, compact conformation, leads to
The flame-retardant filler and waterproof layer set is crossed, makes cable that there is excellent fire performance and flame-retarding characteristic, cable is still during fire
Can continued power for a period of time, cable is nonflammable, and can prevent the expansion spread with disaster of flame, is set while passing through
Oxygen barrier layer, it is free of halogen, smoke amount is small, be conducive to personnel escape, and environment protection, rat is added in oversheath and prevent
Ant repellant, so that rat-and-ant proof purpose is reached, while will not be to environmental pollution, technique is simple, and security performance is high, uses work(
It can be easy to promote the use of comprehensively.
