Abstract

The utility model discloses a double-sheath antistatic tensile control cable for movement, which comprises a cable inner core and a cable outer layer, wherein the cable inner core is formed by extruding a nylon yarn braided reinforcing layer on three stranded conductive wire cores, a tensile steel wire is arranged inside a space formed by the three conductive wire cores in contact, and a flame retardant filling layer is arranged in a space between an external space and the nylon yarn braided reinforcing layer; each conductive wire core is formed by sequentially extruding a fire-resistant layer, a conductor shielding layer, an XLPE insulating layer and an insulated shielding layer on conductors from inside to outside, and a drainage wire core is arranged in each conductor shielding layer; and the cable outer layer is formed by sequentially extruding a wrapping layer, a semiconductive water-blocking layer, a tinned copper wire braided shielding layer, a neoprene inner sheath, an aluminum-plastic composite belt and a flame retardant fireproof outer sheath on the cable inner core from inside to outside. The double-sheath antistatic tensile control cable for movement has the advantages of anti-static property, double sheath protection, conductors not prone to break, tensile resistance, high voltage impact resistance, and excellent waterproof, fireproof and shielding performances.

Description

A kind of pair of sheath antistatic tensile moving control cables

Technical field

The utility model relates to field of cables, relates in particular to a kind of pair of 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.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of pair of sheath antistatic tensile moving control cables.

The utility model takes following technical scheme to realize: a kind of pair of 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 utlity model has in sum following beneficial effect: this cable has antistatic, duplex sheath protection, conductor is frangibility not, resistance to tension, high pressure resistant impact, waterproof, the feature that fire-resistant, shielding properties is good.
