Abstract

The utility model discloses an intrinsically safe computer shielded cable for tension-resistant conductor movement, which comprises a plurality of conductors; an insulating layer is arranged outside each conductor; another insulating layer is arranged outside the insulating layer; a cabling and cable core wrapping layer is arranged outside the insulating layer; a drain wire is arranged outside the cabling and cable core wrapping layer; a sub-shielding layer is arranged outside the drain wire; a total shielding layer is arranged outside the sub-shielding layer; and a sheath layer is extruded outside the total shielding layer. The intrinsically safe computer shielded cable disclosed by the utility model is simple in structure and convenient in manufacture, and can reduce the outer diameter of the cable, save space, reduce production cost of enterprises, improve the qualified rate of products, and improve the production efficiency of enterprises.

Description

A kind of tension conductor moves with intrinsic safety computer shield cable

Technical field

The utility model relates to the tension conductor and moves with computer shielded type cable field, relates in particular to a kind of tension conductor and moves with intrinsic safety computer shield cable.

Background technology

Along with society constantly advances; The user requires also increasingly high to cable performance, to moving with the requirement of cable too, requirement also is increasingly high; If cable does not have good flexibility and good tensile property, influence the useful life of electric wire so to a great extent.At present domesticly be fit to move a lot with the insulation and the sheath material of cable, and tensile structure adopts mostly and adds the both sides that place round cable or the both sides of flat cable, when equipment is installed, reinforcement tension steel wire is connected in required computer control system gets final product.And the device that does not connect the tension steel wire on the regulator cubicle of considerable mobile device is arranged at present; And some computer control system connecting line is too many, and also because increased the tensile structure of cable, the external diameter of cable also increases much simultaneously; Occupied the computer control system space; So there has not been the shelter of above-mentioned tensile structure, now more and more users also is lattice more and more to the requirement of explosion proof of cable, so the generation of intrinsic safety cable also is inevitable.

The utility model adopts conductor and strengthens the stranded together back of tension finer wire wrap insulate; Then stranded, the aluminium foil of core divides shielding, stranding, band, the total screen of aluminium foil, wrap jacket; Through the change of conductor and tension, itself has just become the tension conductor conventional conductor, and the outside diameter of cable has also reduced much simultaneously; Need not the connection tensile device on the user's computer control system like this, also practiced thrift the space of computer control system simultaneously.During electric installation if conductor is connected just passable, so more convenient to use.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of tension conductor to move with intrinsic safety computer shield cable, can reduce the outside diameter of cable, and conserve space reduces the enterprise production cost, improves product percent of pass, improves enterprises production efficiency.

The utility model for the technical scheme that solves its technical problem and adopt is: the utility model relates to a kind of tension conductor and moves with intrinsic safety computer shield cable, comprises many conductors, has been provided with insulating barrier in the many conductors outsides; Outside insulating barrier, be provided with insulating barrier; Stranding and core wrap are arranged outside insulating barrier, outside stranding and core wrap, drainage thread is arranged, outside drainage thread, be provided with sub-shield; Total screen is arranged outside sub-shield, outside total screen, extrude restrictive coating.

As the further improvement of the utility model, said conductor adopts many annealing oxygen-free copper bars to draw the stranded bunchy formation of the copper wire that forms, and general section is 0.75～2.5m ㎡.

As the further improvement of the utility model, said insulating layer material selects flexible PVC.

The beneficial effect of the utility model is: can reduce the outside diameter of cable, conserve space reduces the enterprise production cost, improves product percent of pass, improves enterprises production efficiency.
