Abstract
The utility model relates to a copper-wire-woven shielding transponder data transmission cable, which comprises a cable core and a protective layer coating the cable core, wherein pair wire groups are disposed inside the cable core; each pair wire group is formed by twisting two insulating single lines in different colors; each insulating single line consists of a conductor and an insulating layer coating the periphery of the conductor; and the protective layer comprises a non-moisture-absorbent insulating layer, a copper-wire-woven shielding layer and an outer sheath from inside to outside.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of copper wire woven shielding answering machine data transmission cable.
Background technology
Safety is the eternal theme of railway transportation.Along with the great-leap-forward development of railway " at a high speed, heavy duty ", the development that Chinese the sixth time speed-raising and Line for Passenger Transportation, high ferro are built, railway transportation safe, stable most important.Answering machine data transmission cable of the prior art exists bending property poor, is difficult to construction during house wiring, and the complexity that continues, and the shortcoming such as the antijamming capability of cable is relatively poor, and stable signal transmission is bad can't satisfy high-speed railway to the requirement of cable.
Summary of the invention
The utility model purpose is to provide a kind of good bending property for the deficiency that overcomes existing answering machine data transmission cable technology, and antijamming capability is strong, and signal transmission performance is stable, and the copper wire woven that is easy to construct shielding answering machine data transmission cable.
For achieving the above object, the utility model solves the scheme that its technical problem takes and is:
This copper wire woven shielding answering machine data transmission cable, comprise cable core and be coated on the outer sheath of cable core, be provided with in the described cable core the line group, described the line group is formed by the insulated single wire of two different colours is stranded, described each insulated single wire is comprised of conductor and the insulating barrier that is coated on the conductor periphery, and described sheath is disposed with non-hygroscopic insulating barrier, copper wire woven screen and oversheath from the inside to the outside.
Preferably, described conductor is flexible conductor and adopts lay configuration that described conductor nominal cross is 0.75mm
2, overall diameter is 1.14 mm.
Preferably, described woven shield braiding tightness be not less than 85% and its diameter be not less than 0.1 mm.
The utility model compared with prior art has following advantages: this copper wire woven shielding answering machine data transmission cable adopts the flexible conductor lay configuration, solved answering machine data transmission cable of the prior art in the laying installation process because conductor is hard, the problems such as the fracture that conductor occurs after through bending repeatedly and constructional difficulties; Select polyolefine material to be used as the insulated single wire insulating barrier, make cable have excellent ageing-resistant performance and mechanical strength.In addition, select polyolefine material to be used as the insulated single wire insulating barrier, insulating barrier and conductor are bonded together better, guarantee electric stability and the moisture resistance of insulation system; Cable core adopts the non-hygroscopic insulating barrier to coat outward, can improve the humidity resistance of cable, increases stability and the symmetry of cable core structure; Adopt the copper wire woven shielding as screen, make the cable flexibility good, shielding properties is strong, improves the interference free performance of cable; Select different sheath materials according to the difference of use occasion, can make cable application wider, prolong the useful life of cable.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model copper wire woven shielding answering machine data transmission cable structural representation.
Among the figure: 1, cable core; 2, insulated single wire; 3, conductor; 4, insulating barrier; 5, non-hygroscopic insulating barrier; 6, copper wire woven screen; 7, oversheath.
Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in detail:
A kind of copper wire woven shielding answering machine data transmission cable shown in Figure 1, comprise cable core 1 and the sheath that is coated on outside the cable core 1, be provided with in the described cable core the line group, described to insulated single wire 2 stranded form of line group by two different colours, described each insulated single wire 2 is comprised of conductor 3 and the insulating barrier 4 that is coated on conductor 3 peripheries, and described sheath is disposed with non-hygroscopic insulating barrier 5, copper wire woven screen 6 and oversheath 7 from the inside to the outside.Described can also be quad to the line group.
Described conductor is flexible conductor and adopts lay configuration that described conductor nominal cross is 0.75mm
2, overall diameter is 1.14 mm.
Described insulating barrier is polyolefin insulation layer.
Described woven shield braiding tightness be not less than 85% and its diameter be not less than 0.1 mm.
This copper wire woven shielding answering machine data transmission cable adopts the flexible conductor lay configuration, solved answering machine data transmission cable of the prior art in the laying installation process because conductor is hard, the problems such as the fracture that conductor occurs after through bending repeatedly and constructional difficulties; Select polyolefine material to be used as the insulated single wire insulating barrier, make cable have excellent ageing-resistant performance and mechanical strength.In addition, select polyolefine material to be used as the insulated single wire insulating barrier, insulating barrier and conductor are bonded together better, guarantee electric stability and the moisture resistance of insulation system; Cable core adopts the non-hygroscopic insulating barrier to coat outward, can improve the humidity resistance of cable, increases stability and the symmetry of cable core structure; Adopt the copper wire woven shielding as screen, make the cable flexibility good, shielding properties is strong, improves the interference free performance of cable; Select different sheath materials according to the difference of use occasion, can make cable application wider, prolong the useful life of cable.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
