Abstract

The invention discloses a double-sheath anti-static tensile movable control cable. The double-sheath anti-static tensile movable control cable comprises a cable inner core and a cable outer layer. The cable inner core is formed by twisting three conductive cable cores in a nylon yarn woven strengthened layer in an extruded mode, a tensile steel wire is arranged in the space formed after the three conductive cable cores are arranged in a contacting mode, and an anti-inflaming filling layer is arranged in the space between the external space and the nylon yarn woven strengthened layer; the conductive cable cores are formed by sequentially arranging fireproof layers, conductor shielding layers, XLPE insulation layers and insulation shielding layers on conductors from inside to outside in an extruded mode, and a drainage cable core is arranged in each conductor shielding layer; the cable outer layer is formed by sequentially arranging a lapping layer, a semi-conductive water-blocking tape, tin plated copper wire woven shielding layer, a neoprene inner sheath, an aluminum plastic composite strip and an anti-flaming fireproof outer sheath on the cable inner core from inside to outside in an extruded mode. The cable has the anti-static, tensile, high-voltage-impact-resistant, waterproof and fireproof advantages, and further has the advantages that the cable is not prone to being broken due to double-layer sheath protection, and the shielding performance is good.

Description

A kind of two sheath antistatic tensile moving control cables

Technical field

The present invention relates to field of cables, relate in particular to a kind of two sheath antistatic tensile moving control cables.

Background technology

Current normally used tension mobile cable, cable insulation or restrictive coating are torn the breakage core that causes switching on and are short-circuited because frequent folding and unfolding causes; Cable for a long time out of doors instructions for use cable there is high and low temperature resistance and the performance such as weather-proof.This just requires cable to have certain horizontal stretching resistance, anti-shearing, resistance to bending, high-low temperature resistant, advantage such as weather-proof of bearing, but common cable can not be tackled high microthermal climate, and tensile strength is low, can not be dilatory at ground moving, a little less than antistatic performance, the feature of fire prevention, poor water resistance, therefore, need to provide a kind of new technical scheme to solve the problems referred to above.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of two sheath antistatic tensile moving control cables.

The present invention takes following technical scheme to realize: a kind of two sheath antistatic tensile moving control cables, comprise cable inner core and cable outer layer, cable inner core extrudes three stranded forming of conductor wire core by nylon yarn braiding strengthening layer, the interior volume of three conductor wire core contact formation is provided with a tension steel wire, and the spatial placement between space outerpace and nylon yarn braiding strengthening layer has fire-retardant packed layer; Described conductor wire core is to be from inside to outside extruded on conductor and to form successively by flame retardant coating, conductor shield, XLPE insulating barrier and insulation screen, is provided with a drainage core in conductor shield; Cable outer layer is to be extruded in from inside to outside on cable inner core and to form successively by lapping layer, semiconductive waterstop, tinned copper wire woven shield, neoprene inner sheath, aluminium-plastic tape and fire-retardant fireproof oversheath.

Described conductor adopts that tinned copper wire is stranded to be formed.

The present invention has following beneficial effect in sum: this cable has antistatic, duplex sheath protection, and conductor is frangibility not, resistance to tension, high pressure resistant impact, waterproof, the feature that fire-resistant, shielding properties is good.
