Abstract
The utility model discloses a reinforced intrinsically safe computer shielded cable, 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 reinforced intrinsically safe computer shielded cable 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
Technical field
The utility model relates to the computer shield field of cables, relates in particular to a kind of reinforced 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; It also is increasingly high requiring, and for this reason, the utility model provides a kind of reinforced intrinsic safety computer shield cable; Can reduce the outside diameter of cable, conserve space reduces the enterprise production cost; Improve product percent of pass, improve enterprises production efficiency.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of reinforced 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 reinforced 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 (1) 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 barrier (3) material selects flexible PVC.
As the further improvement of the utility model, said sub-shield (6) and total screen (7) adopt wrapped aluminum foil shielded, and the average wrapped rate of putting up is not less than 15%.
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.
