Abstract
The invention discloses a movable anti-flaming pull-resistant flexible cable used for a coal mine. The movable anti-flaming pull-resistant flexible cable is composed of main power wire cores, insulation wire cores, a copper-clad steel armored layer and an outer polyester tape sheath, wherein fluororubber insulation layers are wrapped on three conductive wire cores in an extruded to form the main power wire cores, and a ground wire core is arranged among of the three conductive wire cores; polyvinyl chloride sheaths and silver plated copper wire stranded conductors are sequentially wrapped on high-strength pull-resistant fiber cores in an extruded mode from outside to inside to form the insulation wire cores; the two main power wire cores and the two insulation wire cores are tightly arranged at intervals, and the polyethylene insulation layer is wrapped on the two main power wire cores and the two insulation wire cores to form a cable core; the copper-clad steel armored layer and the outer polyester tape sheath are wrapped on the cable core in an extruded mode from inside to outside; a pull-resistant steel wire is arranged in the center of the cable core. The movable anti-flaming pull-resistant flexible cable has the advantages of being large in pull force resistance, resistant to shearing, bending, flaming, high temperature and lower temperature, stable in current and the like.
Description
Technical field
The present invention relates to cable, relate in particular to a kind of coal mine moving flame-retardant pull tension flexible cable.
Background technology
Current normally used tension mobile cable, there is the shortcoming such as can not high-low temperature resistant weather-proof, the tensile cable that moving field share, particularly have out of doors under the unsettled occasion of certain span or cable high speed folding and unfolding occasion, cable is bearing very large stretching resistance and shearing force, is not in use easy to occur conductor thread core fracture through strengthening the cable of structural design; Especially as Coal Electricity cable, this cable for a long time out of doors instructions for use cable there is high and low temperature resistance and the performance such as fire-retardant, tension, the performance such as wear-resisting.This just requires to develop a kind of certain horizontal stretching resistance, anti-shearing, resistance to bending, fire-retardant, high-low temperature resistant, novel cable of the advantages such as current stabilization of bearing that have.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide a kind of coal mine moving flame-retardant pull tension flexible cable.
The solution of the present invention is as follows: a kind of coal mine moving flame-retardant pull tension flexible cable, it is made up of active force core, insulated wire cores, copper covered steel armour and polyester belt oversheath, described active force core is to extrude three conductor wire cores by fluorubber insulating barrier to form, and is provided with a ground wire core in the middle of three conductor wire cores; Described insulated wire cores ecto-entad extrudes high-strength tensile fibre core with pvc sheath and silver-gilt copper wire stranded conductor successively and forms; Two active force cores and two insulated wire cores interval close-packed arrays, extruded into cable core by polyethylene layer; Described cable core is from inside to outside extruded with copper covered steel armour and polyester belt oversheath outward successively; In the middle of described cable core, be provided with a tension steel wire.
Described conductor wire core is to extrude two aluminium alloy conductors by polyvinyl chloride insulation layer to form.
Beneficial effect of the present invention: cable of the present invention has large, anti-shearing, the resistance to bending of stretching resistance, fire-retardant, high-low temperature resistant, the advantages such as current stabilization.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described;
As shown in Figure 1, a kind of coal mine moving flame-retardant pull tension flexible cable, it is made up of active force core, insulated wire cores, copper covered steel armour 5 and polyester belt oversheath 6, described active force core is to extrude three conductor wire cores by fluorubber insulating barrier 9 to form, and is provided with a ground wire core 10 in the middle of three conductor wire cores; Described insulated wire cores ecto-entad extrudes high-strength tensile fibre core 2 with pvc sheath 4 and silver-gilt copper wire stranded conductor 3 successively and forms; Two active force cores and two insulated wire cores interval close-packed arrays, extruded into cable core by polyethylene layer 1; Described cable core is from inside to outside extruded with copper covered steel armour 5 and polyester belt oversheath 6 outward successively; In the middle of described cable core, be provided with a tension steel wire 11.
Described conductor wire core is to extrude two aluminium alloy conductors 7 by polyvinyl chloride insulation layer 8 to form.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and revise; when its function producing does not exceed spiritual that specification contains yet, all should be within protection scope of the present invention.
