Abstract

The utility model relates to a cable for lifter, which comprises at least three cores of wire, an insulation layer, a core filled lining, and an outer sheath, wherein the core filled lining is positioned middle of cable, a conducting element is made up by the conducting cores of wire covered with the insulation layer, the conducting element is arranged near to each other, and is positioned on the core filled lining, the outer sheath is positioned on the outside of the conducting element. The utility model is characterized in that an inner sheath and an anti-torsion layer are positioned between the conducting layer and the outer sheath, and the core filled lining positioned in the middle of cable is a strengthen core. The utility model has the advantages of being able to eliminate effectively twisting stress, so as to prolong the service life.

Description

The lift cable

Technical field

The utility model relates to a kind of lift cable, can be used for the electrical equipment control of building hoist, belongs to the cable technology field.

Background technology

The cable of the electrical equipment control of building hoist use at present is universal rubber sleeve flexible cable, as shown in Figure 1, by conductor wire core 1, insulating barrier 2, fill out lining core 3 and oversheath 4 and form, its shortcoming is that torsional stress can not effectively be eliminated in lifting process, useful life is short, generally uses promptly to be short-circuited in 1～3 month.

Summary of the invention

The purpose of this utility model is that invention a kind ofly can effectively be eliminated torsional stress, the lift cable that increases the service life.

For realizing above purpose, the technical solution of the utility model provides a kind of lift cable, comprise at least three conductor wire cores, insulating barrier, fill out lining core and oversheath, filling out the lining core is cable center, fill out the lining core and be provided with one deck outward, outside conducting element, be provided with oversheath, it is characterized in that by adjacent conducting element that is twisted into of the conductor wire core that is extruded with insulating barrier, be provided with inner sheath and the anti-layer of turning round between conductive layer and oversheath, cable center establishes, and to fill out the lining core be strengthening core.

Described strengthening core material is the high strength aramid fiber; Described jacket material is high-intensity TPU thermoplastic elastomer; The described anti-layer of turning round is fibrage.

The utility model adopts the high strength aramid fiber to make strengthening core in cable center, between interior oversheath, increase the anti-layer of turning round of fibrage, can effectively eliminate torsional stress, jacket material adopts high-intensity TPU thermoplastic elastomer, except can significantly improving product flex life, also have the performance of good oil resistant, low temperature resistant, ultraviolet-resistant aging, can increase the service life.

The utility model has the advantages that and effectively to eliminate torsional stress, increase the service life.

Description of drawings

Fig. 1 is a former lift construction of cable schematic diagram;

Fig. 2 is the utility model lift construction of cable schematic diagram.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

As shown in Figure 2, be the utility model lift construction of cable schematic diagram, described lift is made up of 5 conductor wire cores 1, insulating barrier 2, oversheath 4, strengthening core 5, inner sheath 6 and the anti-layer 7 of turning round with cable, the strengthening core 5 that cable center makes for the high strength aramid fiber, be twisted into one as conducting element with 5 conductor wire cores 1 that are extruded with insulating barrier 2 then, with the anti-layer 7 of turning round of folder one deck fibrage between the oversheath 4 of PVC inner sheath 6 and high-intensity TPU thermoplastic elastomer cable formed in 5 wire core 1 claddings that are extruded with insulating barrier 2 again.

The utility model uses in lift, and torsional stress can effectively be eliminated in lifting process, increases useful life.
