Wrapped, the water blocking layer is the compound waterstop of water-swellable, and the flame-retardant layer is that to be more than 50, thickness be 0.25mm's to oxygen index (OI)
Halogen glass fiber tape is wrapped, and the sheath is to extrude LSOH anti-flaming oxygen barrier layer.
Described conductor presses circular copper conductors structure using twisted, and conductor copper cash meets the rule of GB/T3953-2009
Fixed, the structure and D.C. resistance of conductor meet the regulation of GB/T3956-2008.
Total insulating barrier is disposably extruded by conductor shield, insulating barrier, the three-layer co-extruded technology of insulation screen, is insulated
Layer is insulated using crosslinked polyethylene (XLPE), and screen layer uses ultra-smooth semi-conductive screen.
The metal screen layer uses brass wire shielding structure, by dredge around annealed copper wire form, on surface, backlass is wrapped
One layer of soft copper band tightens.
The water blocking layer is wrapped using bilayer, and every layer of cap rate is not less than 30%, ensures that cable often locates waterstop not less than 2
Layer.
The metal armor layers are soft copper band armor.
The oversheath is extrudes using the low-smoke halide-free fireproof composite polyolefine material of black, added with termite-proofization in sheath
Learn additive.
The beneficial effects of the utility model：
First, the twisted of conductor is pressed on provided with being carried out on dust arrester frame winch, is drawn using nanocrystalline diamond composite coating
Mould, effectively increase the tightening factor of conductor, it is ensured that conductor rounding, surface are smooth, reduce the stranding effect and conductor of conductor
Loss, makes conductor bends performance more excellent in mechanical performance.
2nd, the semiconductive nylon tape that the thickness degree of wrapped l~2 is about 0.2mm outside insulated wire cores, can effectively prevent from dredging around
Copper wire is strangled into insulation screen in production and in, avoids copper wire from dredging around the damage to insulated wire cores.
3rd, using copper wire and copper strips combination shielding, the short circuit current requirement of subway is met.
4th, from the compound waterstop of water-swellable, using double-deck wrapped, water can be effectively prevented to pass through screen layer and fire-retardant
Gap between layer is along cable vertical migration.
5th, cable uses oxygen index (OI) wrapped for 0.25mm Halogen glass fiber tape more than 50, thickness, not only with high resistant
Fire characteristic and with protection against rodents effect.Using double-deck wrapped, every layer of cap rate is not less than 60% so that cable often place without halogen glass
Fiber 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, on the one hand can resist injury of certain external force to cable and prevent mouse,
Destruction of the termite to cable；Another aspect metal armor layers can also improve the fire resistance of cable.The cable of copper strips armouring simultaneously
Bending property it is preferable, 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, is added in formula pair
Human body and the nontoxic termite-proof chemical addition agent of environment.The outer jacket of black can also meet that cable is wanted to antiultraviolet
Ask, the service life of sheath when extending cable outdoor laying.
8th, the product is using the structure design of original creation and using new material, new technology, and product has Halogen, low cigarette, fire-retardant
A classes, waterproof, protection against rodents, termite-proof performance, it is fully able to meet the requirement that urban track traffic uses.
