Ask, while south is overcast and rainy moist, the harmful organisms such as mouse and termite to the safe operation of the electric utilities such as electric wire bring compared with
Big hidden danger, therefore urban track traffic cable is in addition to the requirement for possessing common cable, it is necessary to possess environmentally friendly, low cigarette
The characteristics such as Halogen, high fire-retardance, waterproof, antiultraviolet, rat-and-ant proof.Existing track traffic does not adapt to track traffic with midium voltage cable
Special use requirement.
The content of the invention
The purpose of the present invention be exactly to overcome above-mentioned the deficiencies in the prior art, provide it is a kind of have excellent environmentally friendly, low cigarette without
The track traffic of the characteristics such as halogen, high fire-retardance, waterproof, antiultraviolet, rat-and-ant proof is extraordinary electric with being pressed in A class fire-resistant waterproof rat-and-ant proofs
Cable.
The technical scheme is that：The cable includes conductor, and three-layer co-extruded lead is set gradually outside the conductor
Body shielded layer, insulating layer, insulation screen, lapping layer, metal screen layer, water blocking layer, flame-retardant layer, sheath, metal armor layers,
Oversheath, the sheath to extrude LSOH anti-flaming oxygen barrier layer, the oxygen barrier layer by two layers of alkali-free glass silk ribbon around
Bag is formed, and the oversheath extrudes optical cement for low-smoke non-halogen flame-retardant termite-resistant rodent-resistant high polymer material and forms, and the thickness of optical cement is
10-20 μm, which is polyvinyl chloride oversheath, is added in oversheath nontoxic to human body and environment termite-proof
Plant additive.
The conductor of the cable presses circular copper conductors structure using twisted, and conductor copper wire meets the rule of GB/T 3953-2009
Fixed, the structure and D.C. resistance of conductor meet the regulation of GB/T 3956.2008.
The insulation system is disposably squeezed out using conductor shield, insulating layer, the three-layer co-extruded technology of insulation screen, and insulation is adopted
With crosslinked polyethylene (XLPE) material, polymeric barrier layer materials use ultra-smooth semiconductive shieldin material.
The lapping layer is wrapped for semiconductive nylon tape.
The metal screen layer use brass wire shielding structure, by dredge around annealed copper wire form, wrapped one layer of backlass on surface
Soft copper band tightens.
The water blocking layer selects the compound waterstop of water-swellable, wrapped using bilayer, and every layer of cap rate ensures not less than 30%
Cable often locates waterstop not less than 2 layers.
It is wrapped for the Halogen glass fiber tape of 0.25mm that the flame-retardant layer uses oxygen index (OI) to be more than 50, thickness.
The metal armor layers are soft copper band armor.
Beneficial effects of the present invention：
1st, the twisted of conductor is pressed on equipped with being carried out on dust-extraction unit frame winch, using nanocrystalline diamond composite coating drawing-die, is had
Effect improves the tightening factor of conductor, it is ensured that and conductor rounding, surface are smooth, reduce the stranding effect and conductor losses of conductor,
Make conductor bends performance more excellent in mechanical performance.
2nd, the semiconductive nylon tape that the layer thickness of wrapped l~2 is about 0.2mm outside insulated wire cores, can effectively prevent from dredging around copper wire
It is strangled in production and use into insulation screen, copper wire is avoided to dredge around the damage to insulated wire cores.
3rd, using copper wire and copper strips combination shielding, the short circuit current flow requirement of subway is met.
4th, select the compound waterstop of water-swellable, using double-deck wrapped, can effectively prevent water by shielded layer and flame-retardant layer it
Between gap along cable vertical migration.
5th, cable uses oxygen index (OI) wrapped for the Halogen glass fiber tape of 0.25mm more than 50, thickness, not only special with high fire-retardance
Property and with protection against rodents effect.Wrapped using bilayer, every layer of cap rate is not less than 60% so that cable often locates Halogen glass fibre
Band is not less than 4 layers, it is ensured that cable-flame retardant performance reaches the requirement of A classes.
6th, there is provided copper strips metal armor layers, certain external force on the one hand can be resisted to the injury of cable and prevents mouse, termite
Destruction to cable；Another aspect metal armor layers can also improve the flame retardant property of cable.The cable of copper strips armouring is curved simultaneously
Bent better performances also allow for laying in construction.
7th, the outer jacket of cable is extruded using the low-smoke halide-free fireproof composite polyolefine material of black, add in formula to human body and
The nontoxic termite-proof chemical addition agent of environment.The outer jacket of black can also meet requirement of the cable to antiultraviolet, extend
The service life of sheath during cable outdoor laying.
8th, the product using original creation structure design and using new material, new process, product have Halogen, low cigarette, fire-retardant A classes,
Waterproof, protection against rodents, termite-proof performance are fully able to meet the requirement that urban track traffic uses.
