Send on machine, shuttle car moves back and forth in the course of the work, and cable is by the roller automatic deploying and retracting on shuttle car, it may occur that
Serious bending and dilatory, while also being impacted by the coal cinder and stone fallen, it is easy to make cable conductor be broken and sheath
Breakage, so as to occur short circuit, if blast will be produced by running into gas.When running into fire, cable fire can be produced and substantial amounts of had again
Poisonous gas, make the life security of people be threatened by very big.
The content of the invention
The present invention has wear-resisting, tension to solve problem of the prior art there is provided one kind, antitorque, counter-bending, anti-quiet
Electric, anti-interference, low smoke and zero halogen colliery low smoke and zero halogen shuttle car cable.
A kind of colliery low smoke and zero halogen shuttle car cable of the present invention, including cable core, described cable core is by three power lines
Core, the wire core and a supervision core of two nakeds are constituted；Environment-friendly type expansible fire trapping mould is provided with the hollow position of cable core
Block, described cable core is externally provided with semiconductive band, and semiconductive band is externally provided with the low smoke and zero halogen resistance using ethylene-propylene diene copolymer as base-material
Fire outside braiding aramid fiber silk enhancement layer outside rubber inner sheath, low-smoke non-halogen flame-retardant rubber inner sheath, aramid fiber silk enhancement layer
Provided with the low-smoke non-halogen flame-retardant rubber oversheath using ethylene-propylene diene copolymer as base-material, in low-smoke non-halogen flame-retardant rubber oversheath outer surface
Coated with paraffin.
Further improve, described power wire core is exhausted by power wire core conductor, the power wire core being extruded in outside power wire core
Edge layer and the metal knitted screen layer being woven in outside power wire core insulating barrier are constituted.
Further improve, described wire core is by ground wire core conductor and is arranged on the fiber at ground wire core conductor center and strengthens
Core is constituted.
Further improve, described supervision core by supervision core conductor, be arranged on the fiber at supervision core conductor center
Strengthening core and the metal knitted screen layer being woven in outside supervision core conductor are constituted.
Further improve, described power wire core conductor is twisted again after multiply tin annealed copper wire stock strand to be formed, and stock twists pitch diameter
Than controlling below 12 times, the lay ratio twisted again is controlled below 10 times.
Further improve, the power wire core insulating barrier is semi-conductive tape insulating barrier.
Further improve, the ground wire core conductor is using six class tin annealed copper wires with 500 type wrapping machine layered windings anti-
Formed in wire drawing.
Further improve, the supervision core conductor twists composition through 400 type bunchers stocks for high intensity spinning synthetic fibre silk fiber and led
Tin plating soft copper silk is wound after the tension silk of body in tension silk higher slice again to form, every layer of winding direction is on the contrary, outermost winding
Direction is left-hand.
Compared with prior art, beneficial effect of the present invention is：
1st, environment-friendly type expansible fire trapping module is a kind of novel fireproof blocking material, using nontoxic expanding material and special process system
Into being mainly used in the fireproof blocking of the electric wire, cable, electrical equipment of the industries such as petrochemical industry, electric power, communication, metallurgy, the product is combined
All advantages of traditional organic fire prevention calking, inorganic fireproofing plugging and back-fire relief bag, toxic gas will not be produced by meeting fire, not flown
Cigarette, do not fall off, environmental protection, high mechanical strength, it is flexible containing a small amount of efficiently cross-linked material, be conducive to protecting cable；
The cable quality is light, and actual measurement environment-friendly type back-fire relief expansion module dry density is 0.68t/m3, quality is far below national standard not
More than 2.5t/m3Requirement, plugging material can be mitigated significantly to cable testing bridge and the load of building；
The cable fire time is long, and because guarantor's type back-fire relief expansion module is constituted using special formulation material, heat conductive is very
Difference, can prevent to ignite to penetrate, fire resistance period is risen to more than 5h, more than 3h standards as defined in country-level fire-proof product；
2nd, conductor spins the tension silk that synthetic fibre silk fiber twists composition conductor through stock using high intensity.Twined using the layering of six class tin annealed copper wires
It is wound on high intensity, on the tension of high bending property silk, every layer of winding direction is on the contrary, outermost winding direction is left-hand, structure
Into supervision core conductor.This structure type pitch very little, its length is the 1.3~1.5 of raw footage after the expansion of conductor monofilament
Times, cable is when bending and being dilatory, and conductor is just as a spring, and most active force is all concentrated on tension silk, so as to have
Avoid to effect cable conductor and be pulled off and break with curved.Layer of metal screen layer is woven after supervision core extruded insulation, thus can
It is effectively prevented from interference of the extraneous power supply signal to monitoring circuit.
Ground wire core conductor equally uses six class tin annealed copper wire layered windings on tension silk, ground wire core conductor naked
Layer, improves the antistatic effect of cable.
To ensure that shuttle car cable has preferable flexibility, power wire core conductor uses six class conductor structures；Multiply is tin plating soft
Copper cash stock is twisted again after twisting, and conductor stock twists lay ratio control below 12 times, and the lay ratio twisted again is controlled below 10 times, and
Twisted for stock and strand direction identical concentric type is regular stranded again, outer layer direction of lay is left-hand.Each in such a stranded mode
The position of strand is in turn in the elongation zone and the compressional zone of twisted wire bottom on twisted wire top, and when twisted wire is bent, conductor will not occur
Deformation fracture, makes its flexibility and ductility more preferable.In order to improve Electric Field Distribution, homogenizing electric field and the elimination conductor of conductive surface
The air gap between insulating barrier, while the sophisticated projection such as burr during preventing conductor strand is pierced into insulating barrier, first wrapped one layer
Extruded insulation formation insulated wire cores, then weave layer of metal screen layer, it is to avoid interference to external world after semi-conductive tape.
3rd, power wire core metal and fibrage shielded, and wire core does not insulate, it is wrapped outside stranding cable core partly to lead
Electric band also just increases the contact surface of power wire core shielding and wire core, whole when so in cable insulation, any one sustains damage
Individual equipment can all be powered off immediately, and underground will not cause danger because of cable fault.
4th, the enhancement layer of cable is woven between inner/outer sheath using aramid fiber yarn, and the critical close combination of interior oversheath；Interior,
Oversheath uses oil resistant, heat-resisting, corrosion-resistant, the wear-resisting low-smoke non-halogen flame-retardant rubber using ethylene-propylene diene copolymer as base-material to extrude, and makes
The anti-torsion and bending resistance of cable have large increase, while being released when cable meets fire without toxic gas.
5th, the shuttle car construction of cable is optimized, improves the antistatic and antijamming capability and bending resistance of cable
Can, whole equipment can be powered off immediately when cable sustains damage；The oil resistant, resistance to good mechanical physical property has been selected simultaneously
Hot, corrosion-resistant, the wear-resisting low-smoke non-halogen flame-retardant rubber using ethylene-propylene diene copolymer as base-material is sheath material, in cable fire not
Toxic gas is produced, making the life security of people has guarantee, and service life is long.
6th, the outer coated with paraffin of oversheath, prevents that cable from producing fire by friction the hidden danger brought in dragging.
