Description

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

Technical field

The utility model relates to the computer shield field of cables, relates in particular to a kind of tension conductor and moves with oil resistant 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 on the required computer control system gets final product.And the device that does not connect the tension steel wire on the considerable computer control system is arranged at present; And the connecting line on some computer control system is too many; Also because increased the tensile structure of cable, the external diameter of cable also increases a lot, has occupied the limited space of computer control system simultaneously; Be exactly that the actual production place often has a lot of greasy dirts in addition; Quicken the aging of cable; So just there has not been the shelter of above-mentioned tensile structure, also be lattice more and more in more and more users 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, band, aluminium foil divide that shielding, stranding, band, aluminium foil always shield, wrap jacket; Change through conductor and tension; Conventional conductor itself has just become the tension conductor, and the outside diameter of cable has also reduced much to have need not the connection tensile device on the user's computer control system so simultaneously; Also practiced thrift simultaneously the space of computer control system; So the user need not to have changed the computer control system of equipment into the space of the tensile property of cable and computer control system is limited, insulation of selecting for use simultaneously and sheath material have good oil resistant characteristic and explosion-resistance characteristic, and the scope of application that makes the tension conductor move with oil resistant intrinsic safety computer shield cable enlarges more.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of tension conductor to move with oil resistant 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 oil resistant 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 insulating layer material selects flexible PVC.

As the further improvement of the utility model, said stranding and core wrap cable insulation core should twist together, and stranding outermost layer direction of lay is a dextrad, the wrapping of external application nonwoven fabrics band.

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.
