The special-purpose elevator cable has advantages of reasonable, compact and simple structure, easy manufacturing, good use performance, strong anti-interference, anti-compaction and anti-tension capability and long service life.
Description
Technical field
The present invention relates to a kind of structure of elevator cable, belong to cable technology field.
Background technology
Now on market, existing elevator cable often can't meet actual required resistance to tension, and the antijamming capability of holding wire is not also very strong, and power line is while the fault such as being short-circuited, and often needs to change whole elevator cable.These problems have all affected the useful life of elevator cable, and have increased the incidence of elevator accident.Elevator cable is mainly used in frequent mobile elevator, escalator is a small space that is close to sealing, in elevator cable, there is half to be used for extending use, high rise elevator can reach at most more than 100 meter, the deadweight of 100 meters of cables is exactly nearly hundred kilograms, therefore elevator cable need to have stronger resistance to tension, guarantees the cable core that can not break in moving process frequently, and its inner holding wire, power line can not be subject to the interference of cable external electrical field and internal electric field.Therefore,, in the urgent need to providing a kind of tension, anti-pressure ability stronger, antijamming capability is stronger, the elevator cable of longer service life.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, provide a kind of tension, resistance to compression, antijamming capability stronger, the elevator cable of longer service life.
The object of the invention is to be achieved through the following technical solutions: a kind of elevator private cable, comprise restrictive coating and be arranged on signal cable, the power cable in restrictive coating, it is characterized in that, described signal cable by strengthening core, be stranded in strengthening core periphery copper wire conductor, be extruded in insulating barrier on copper wire conductor, be wrapped in the aluminium foil layer on insulating barrier, the shielding layer of copper wires being woven on aluminium foil layer forms; In described restrictive coating, both sides are respectively equipped with by the some stranded reinforcements that form of steel wire; Described power cable is by two pairs of stranded forming of power line, wherein a pair of power line is comprised of the stranded copper wire conductor forming of copper wire, the PVC insulating barrier that is extruded on copper wire conductor, and another is comprised of the stranded copper wire conductor forming of copper wire, the polyethylene layer that is extruded on copper wire conductor power line.
Strengthening core in described signal cable is by 9 stranded forming of steel wire.
The present invention is rational in infrastructure simple, manufactures easily, be provided with two reinforcements in restrictive coating, has solved the move around problem of easily disconnected core in process of cable; Aluminium foil in holding wire plays shielding action, has strengthened the antijamming capability of holding wire together with braiding shielding layer of copper wires, prevents that holding wire is subject to the interference of the external world or internal electric field; Steel wire strengthening core has strengthened the tensile property of cable, make cable in lifting process except bearing the weight of self, can also bear certain weight of object; The setting of 2 pairs of power lines, after wherein a pair of power line breaks down, another is to as stand-by power supply line, the polythene material odorless in polyethylene layer, nontoxic wherein, there is good resistance to low temperature, dielectric property and resistance to chemical corrosion are good, and moulded manufacturability is good, and electrical insulation capability is good.The present invention is simple and reasonable, compact, simple, manufacture easily, serviceability is good, has the characteristic of anti-strong jamming, withstand voltage, tension, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1 strengthening core, 2 copper wire conductors, 3 insulating barriers, 4 aluminium foil layers, 5 shielding layer of copper wires, 6 PVC insulating barriers, 7 polyethylene layers, 8 restrictive coatings, 9 reinforcements.
Embodiment
Elevator private cable, comprises restrictive coating 8, is arranged on signal cable and power cable in restrictive coating, is separately positioned in restrictive coating both sides by the some stranded reinforcements that form 9 of steel wire.Signal cable by strengthening core 1, be stranded in the outer field copper wire conductor 2 of strengthening core, be extruded in insulating barrier 3 on copper wire conductor, be wrapped in the aluminium foil layer 4 on insulating barrier, the shielding layer of copper wires 5 being woven on aluminium foil layer forms.Strengthening core 1 is by 7 stranded forming of steel wire.Power cable is by 2 pairs of stranded forming of power line, wherein a pair of power line is comprised of the stranded copper wire conductor 2 forming of copper wire, the PVC insulating barrier 6 that is extruded on copper wire conductor, and another is comprised of the stranded copper wire conductor 2 forming of copper wire, the polyethylene layer 7 that is extruded on copper wire conductor power line.After wherein a pair of power line breaks down, another is to as stand-by power supply line.
In restrictive coating, be provided with two reinforcements, solved the move around problem of easily disconnected core in process of cable; Aluminium foil in holding wire plays shielding action, has strengthened the antijamming capability of holding wire together with braiding shielding layer of copper wires, prevents that holding wire is subject to the interference of the external world or internal electric field; Steel wire strengthening core has strengthened the tensile property of cable, make cable in lifting process except bearing the weight of self, can also bear certain weight of object; The setting of 2 pairs of power lines, after wherein a pair of power line breaks down, another is to as stand-by power supply line, the polythene material odorless in polyethylene layer, nontoxic wherein, there is good resistance to low temperature, dielectric property and resistance to chemical corrosion are good, and moulded manufacturability is good, and electrical insulation capability is good.The present invention is simple and reasonable, compact, simple, manufacture easily, serviceability is good, has the characteristic of anti-strong jamming, withstand voltage, tension, long service life.
