Abstract
The invention relates to a copper-wire-knitted data transmission cable for a shielding transponder, which comprises a cable core and a protective layer coating the cable core, wherein a pair line set is arranged in the cable core; the pair line set is made by stranding two insulating single lines in different colors; each insulating single line comprises a conductor and an insulating layer coating the conductor; and a non-moisture-absorbent insulating layer, a copper-wire-knitted shielding layer and an outer sheath are arranged in the protective layer sequentially from inside to outside.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of copper cash braid shielded answering machine data transmission cable.
Background technology
Safety is the railway transportation Eternal Theme.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, safety of railway transportation, 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 complicacy that continues, and shortcoming such as the antijamming capability of cable is relatively poor, and stable signal transmission property is bad can't satisfy the requirement of high-speed railway to cable.
Summary of the invention
The present invention seeks to provides 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 cash braid shielded answering machine data transmission cable that is easy to construct.
For achieving the above object, the present invention solves the scheme that its technical problem takes and is:
This copper cash braid shielded answering machine data transmission cable; Comprise the sheath that cable core is outer with being coated on cable core; Be provided with in the described cable core the line group; Said the line group is formed by the insulated single wire of two different colours is stranded, said each insulated single wire is made up of conductor and the insulating barrier that is coated on the conductor periphery, and described sheath is disposed with non-hygroscopic insulating barrier, copper cash woven shield and oversheath from the inside to the outside.
Preferably, said conductor is flexible conductor and adopts lay configuration that said conductor nominal cross is 0.75mm
2, overall diameter is 1.14 mm.
Preferably, said woven shield braiding tightness be not less than 85% and its diameter be not less than 0.1 mm.
The present invention compared with prior art has advantage: this copper cash braid shielded answering machine data transmission cable adopts the flexible conductor lay configuration; It is hard owing to conductor in the laying installation process to have solved answering machine data transmission cable of the prior art, problems such as fracture that conductor occurs after the process repeated bending and constructional difficulties; Select for use 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 for use polyolefine material to be used as the insulated single wire insulating barrier, insulating barrier and conductor are bonded together better, guarantee the 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 the stability and the symmetry of cable core structure; Adopt the copper cash braid shielded as screen, make the cable flexibility good, shielding properties is strong, improves the interference free performance of cable; Select different sheath materials for use 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 present invention is further specified.
Fig. 1 is a copper cash braid shielded answering machine data transmission cable structural representation of the present invention.
Among the figure: 1, cable core; 2, insulated single wire; 3, conductor; 4, insulating barrier; 5, non-hygroscopic insulating barrier; 6, copper cash woven shield; 7, oversheath.
Embodiment
Describe the present invention below in conjunction with accompanying drawing and embodiment:
A kind of copper cash braid shielded 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; Said to insulated single wire 2 stranded form of line group by two different colours, said each insulated single wire 2 is made up 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 cash woven shield 6 and oversheath 7 from the inside to the outside.Said can also be quad to the line group.
Said conductor is flexible conductor and adopts lay configuration that said conductor nominal cross is 0.75mm
2, overall diameter is 1.14 mm.
Said insulating barrier is a polyolefin insulation layer.
Said woven shield braiding tightness be not less than 85% and its diameter be not less than 0.1 mm.
This copper cash braid shielded answering machine data transmission cable adopts the flexible conductor lay configuration; It is hard owing to conductor in the laying installation process to have solved answering machine data transmission cable of the prior art, problems such as fracture that conductor occurs after the process repeated bending and constructional difficulties; Select for use 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 for use polyolefine material to be used as the insulated single wire insulating barrier, insulating barrier and conductor are bonded together better, guarantee the 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 the stability and the symmetry of cable core structure; Adopt the copper cash braid shielded as screen, make the cable flexibility good, shielding properties is strong, improves the interference free performance of cable; Select different sheath materials for use 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 invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
