Description

Airport static power source power cable

Technical field

The utility model relates to power transmission cable, is specifically related to a kind of airport static power source power cable.

Background technology

Cable normally forms by several or several groups of wires (often organizing at least two) are stranded around center, the similar rope of its shape, simultaneously outer cover height insulating barrier.

Cable has power cable, control cables, compensating cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable, mining cable, aluminium alloy cable etc.They are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc.

Airport static power source cable generally in use can be long-term bending and pulling, this requirement such as flexibility, tensile strength is high and wear-resisting that just needs cable to have, the cable of the external import of the many employings of cable of this occasion is used in prior art, cost can be caused so high, due to the resilience of cable and toughness deficiency in user's use procedure, cable is usually caused to rupture.

Utility model content

The utility model overcomes the cable of the external import of the many employings of airport static power source cable in prior art, there is the deficiency that cost is high, usually cause cable generation fracture, there is provided that one has excellent toughness, tensile strength is high, rub proofness is high, and meet the airport static power source power cable of airport static power source cable needs.

For achieving the above object, the utility model is by the following technical solutions:

A kind of airport static power source power cable, it comprises cable core, described cable core is provided with inner covering from the inside to the outside successively, braid and oversheath, described cable core is by three power wire core, three neutral cores and six roots of sensation control conductor composition, two power wire core adjacent in three power wire core are tangent between two, and the line in three power wire core cross section centers of circle is equilateral triangle, described neutral core is arranged between two adjacent power wire core, and neutral core and inner covering tangent, described control conductor is separately positioned on neutral core both sides, and control conductor and inner covering tangent.

First by being enclosed with inner covering successively outward at cable core in the technical program, braid and oversheath, pass through inner covering, braid and oversheath protect the cable core of inner signal transmission and electric power conveying successively, thus optimize the performance of cable on the whole, cable is made to have good toughness, tensile strength etc., two power wire core simultaneously by adjacent in three power wire core are tangent between two, and the line in three power wire core cross section centers of circle is equilateral triangle, described neutral core is arranged between two adjacent power wire core, and neutral core and inner covering tangent, position is by the way arranged, power wire core and neutral core are evenly interspersed, thus reach the effect of balanced electric field in transmitting procedure.

Further technical scheme is, described inner covering adopts flame retardant polyurethane to be made by fashion of extrusion.

In the technical program, first inner covering selects tensile strength to be greater than the flame retardant polyurethane of 35Mpa, because polyurethane material has the excellent performance such as high strength, low temperature resistant, wear-resisting and hydrolysis, so inner covering has also possessed above-mentioned performance simultaneously, the mode of extruding is adopted to be arranged on by inner covering on inner cable core, thus make inside respectively organize core (such as, power wire core, neutral core and control conductor) position fixing more firm, avoid in use causing each group of core to produce displacement, improve the stability in the cable course of work.

Further technical scheme is, described braid is adopted polyester to prick yarn and made by weaving manner.

In the technical program, braid adopts polyester bundle yarn to be made by the mode of braiding, first to inner cable core, there is an effect of tightening by the mode of braiding thus prevent cable core to be out of shape, prick yarn due to polyester and there is good mechanical property, so make braid have good tensile strength simultaneously, adopt the surface irregularity of the braid after weaving simultaneously, thus make surface of outer sheath also form rough structure, the area of oversheath and earth surface so just can be made to reduce, thus the frictional force produced in the face of cable with reducing in the process of pulling, thus effectively can protect cable, improve the useful life of cable.

Further technical scheme is, described oversheath adopts polyurethane to be made by fashion of extrusion.

Because oversheath adopts polyurethane in the technical program, because polyurethane material has the excellent performance such as high strength, low temperature resistant, wear-resisting and hydrolysis, so the above-mentioned performance that made oversheath also possess.

Further technical scheme is, described power wire core comprises some stock first conductors, and described first conductor is wrapped with the first insulating barrier.

Further technical scheme is, described neutral core comprises some stocks the 3rd conductor, and described 3rd conductor is wrapped with the second insulating barrier.

Further technical scheme is, described control conductor comprises four second conductors, has tension rope at the center-filled of four second conductors.

There is tension rope by the second conductor central filler of four in control conductor in the technical program, thus improve toughness and the resilience of control conductor.

Further technical scheme is, described first conductor is soft copper silk or tinned copper wire, and described first insulating barrier adopts crosslinked polyethylene to make.

Further technical scheme is, described 3rd conductor is soft copper silk or tinned copper wire, and described second insulating barrier adopts crosslinked polyethylene to make.

Further technical scheme is, described second conductor is soft copper silk or tinned copper wire.

First by the first conductor, the second conductor and the 3rd conductor material being selected copper wire and the tinned copper wire of better softness in the technical program, thus the toughness of power wire core, neutral core and control conductor can be improved, the useful life of cable can be improved in Long-term bend use procedure, then the first insulating barrier and the second insulating layer material are selected crosslinked polyethylene, thus the first insulating barrier and the second insulating barrier can be made to have the performances such as low temperature resistant, cut resistant.

Compared with prior art, the beneficial effects of the utility model are:

Cable of the present utility model has the performances such as excellent toughness, tensile strength is high, rub proofness is high, can meet the requirement that airport static power source cable uses, instead of the use of import cable, saved cost.
