Abstract
The invention discloses a tensile anti-compression anti-interference elevator special-purpose cable, and belongs to the technical field of a cable. The tensile anti-compression anti-interference elevator special-purpose cable comprises a sheath layer with a flat-shaped cross section, and a signal cable and a power supply cable which are arranged in the sheath layer. The two sides in the sheath layer are each provided with a reinforced ribs formed by twisting a plurality of steel wires; the signal cable is composed of a reinforce core, a copper wire conductor twisted at the outer layer of the reinforced core, an insulation layer extruded on the copper wire conductor, an aluminum foil layer wrapping the insulation layer and a copper wire shielding layer braided on the aluminum foil layer; and the power supply cable is formed by twisting two pairs of power supply lines, wherein one pair of power supply lines are composed of copper wire conductors formed by twisting copper wires and a PVC insulation layer extruded on the copper wire conductors, and the other pair of power supply lines are composed of copper wire conductors formed by twisting copper wires and a polyethylene insulation layer extruded on the copper wire conductors. The tensile anti-compression anti-interference elevator special-purpose cable is simple, reasonable and compact in structure, easy to manufacture and produce, good in application performance and long in service life, and also has anti-high-interference, pressure resistance and tensile properties.
Description
Technical field
The present invention relates to the structure of a kind of elevator private cable, belong to field of cable technology.
Background technology
Elevator cable is mainly used in the elevator of frequently movement, escalator is one and is close to the small space closed, elevator cable there is half be used to extension, high rise elevator is at most up to more than 100 meters, the deadweight of 100 meters of cables is exactly nearly hundred kilograms, therefore elevator cable needs have stronger resistance to tension, it is ensured that cable will not break core in moving process frequently, and its internal holding wire, power line will not be subject to the interference of Exterior cable electric field and internal electric field. Existing elevator cable is often not met by actually required resistance to tension currently on the market, and the capacity of resisting disturbance of holding wire is also not as strong, and power line be short-circuited etc. fault time, generally require whole elevator cable of replacing. These problems all have impact on the service life of elevator cable, and adds the incidence rate of elevator accident. Therefore, in the urgent need to providing a kind of tension, anti-pressure ability higher, capacity of resisting disturbance is higher, the elevator cable of longer service life.
Summary of the invention
It is an object of the invention to for above-mentioned the deficiencies in the prior art, it is provided that a kind of tension, resistance to compression, capacity of resisting disturbance are higher, the jamproof elevator private cable of tension resistance to compression of longer service life.
It is an object of the invention to be achieved through the following technical solutions: the jamproof elevator private cable of tension resistance to compression, including the restrictive coating that cross section is flat and be arranged on the signal cable in restrictive coating, power cable, it is characterized in that, in described restrictive coating, be respectively provided on two sides with the reinforcement stranded by some steel wires; Described signal cable by strengthening core, be stranded in the copper wire conductor of strengthening core periphery, the insulating barrier being extruded on copper wire conductor, parcel aluminium foil layer on the insulating layer, the shielding layer of copper wires that is woven on aluminium foil layer form; Described power cable is formed by the two pairs of power lines are stranded, one pair of which power line is made up of the stranded copper wire conductor of copper wire, the PVC insulating barrier that is extruded on copper wire conductor, and power line is made up of by another the stranded copper wire conductor of copper wire, the polyethylene layer that is extruded on copper wire conductor.
Strengthening core in described signal cable is formed by 7 steel wires are stranded.
The present invention is provided with two reinforcements in restrictive coating, solves the problem that cable moves back and forth easily disconnected core in process; Aluminium foil in holding wire plays shielding action, enhances the capacity of resisting disturbance of holding wire, it is prevented that holding wire is subject to the interference of the external world or internal electric field together with braiding shielding layer of copper wires; Steel wire strengthening core enhances the tensile property of cable, makes cable in lifting process except can bearing the weight of self, moreover it is possible to bear certain weight of object; The setting of 2 pairs of power lines, after one pair of which power line breaks down, another is to as stand-by power supply line, the wherein polythene material odorless in polyethylene layer, nontoxic, there is excellent resistance to low temperature, dielectric properties and resistance to chemical corrosion are excellent, and moulded manufacturability is good, and electrical insulation capability is excellent. Present configuration advantages of simple, compact, simple, to manufacture easily, serviceability is good, has the characteristic of anti-strong jamming, pressure, tension, long service life.
Accompanying drawing explanation
Fig. 1 is the 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, 6PVC insulating barrier, 7 polyethylene layers, 8 restrictive coatings, 9 reinforcements.
Detailed description of the invention
The jamproof elevator private cable of tension resistance to compression, including the restrictive coating 8 that cross section is flat, the signal cable being arranged in restrictive coating and power cable, is separately positioned in restrictive coating both sides by the stranded reinforcement 9 of some steel wires.
Signal cable is made up of strengthening core 1, the copper wire conductor 2 being stranded in strengthening core outer layer, the insulating barrier 3 being extruded on copper wire conductor, parcel aluminium foil layer 4 on the insulating layer, the shielding layer of copper wires 5 that is woven on aluminium foil layer. Strengthening core 1 is formed by 7 steel wires are stranded.
Power cable is formed by the 2 pairs of power lines are stranded, one pair of which power line is made up of the stranded copper wire conductor 2 of copper wire, the PVC insulating barrier 6 that is extruded on copper wire conductor, and power line is made up of by another the stranded copper wire conductor 2 of copper wire, the polyethylene layer 7 that is extruded on copper wire conductor. After one pair of which power line breaks down, another is to as stand-by power supply line.
Restrictive coating is provided with two reinforcements, solves the problem that cable moves back and forth easily disconnected core in process; Aluminium foil in holding wire plays shielding action, enhances the capacity of resisting disturbance of holding wire, it is prevented that holding wire is subject to the interference of the external world or internal electric field together with braiding shielding layer of copper wires; Steel wire strengthening core enhances the tensile property of cable, makes cable in lifting process except can bearing the weight of self, moreover it is possible to bear certain weight of object; The setting of 2 pairs of power lines, after one pair of which power line breaks down, another is to as stand-by power supply line, the wherein polythene material odorless in polyethylene layer, nontoxic, there is excellent resistance to low temperature, dielectric properties and resistance to chemical corrosion are excellent, and moulded manufacturability is good, and electrical insulation capability is excellent. Present configuration advantages of simple, compact, simple, to manufacture easily, serviceability is good, has the characteristic of anti-strong jamming, pressure, tension, long service life.
