Abstract
Disclosed in the utility model is a mobile flame-retardant tensile flexible cable for coal mine. The mobile flame-retardant tensile flexible cable is composed of main power wire cores, insulated wire cores, a copper covered steel armored layer, and a polyester tape outer sheath. Three conductive wire cores are extruded by a fluororubber insulating layer to form one main power wire core; and a ground wire core is arranged in the middle of the three conductive wire cores. According to each insulated wire core, a high-strength tensile fiber core is extruded successively by a polyvinyl chloride sheath and silver-plated copper wire twisted conductors from outside to inside. The two main power wire cores and the two insulated wire cores are arranged closely at intervals and are extruded by a polyethylene insulating layer to form a cable core; and the copper covered steel armored layer and the polyester tape outer sheath successively extrude the cable core from inside to outside; and a tensile copper wire is arranged in the middle of the cable core. The provided cable has advantages of high tensile strength, cutting-off resistance, bending resistance, flame retardance, high and low temperature resistance, and stable current and the like.
Description
Technical field
The utility model relates to cable, relates 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.
Utility model content
For overcoming above-mentioned deficiency, the utility model object is to provide a kind of coal mine moving flame-retardant pull tension flexible cable.
Scheme of the present utility model 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.
The beneficial effects of the utility model: the utility model cable has large, anti-shearing, the resistance to bending of stretching resistance, fire-retardant, high-low temperature resistant, the advantages such as current stabilization.
