Abstract
The invention discloses a cable for use in track traffic and relates to the technical field of digital signal cables. The cable for use in track traffic comprises a cable core, two PET wrapping layers, one PPD wrapping layer, a metal sheath, a hot melt adhesive coating layer, an inner cushion layer, a steel band armor and an outer sheath. The cable core is covered by the two PET wrapping layers and the PPD wrapping layer. The wrapping layers are covered by the metal sheath. The metal sheath is covered by the hot melt adhesive coating layer. The hot melt adhesive coating layer is covered by the inner cushion layer. The inner cushion layer is wrapped by the steel band armor, and the steel band armor is covered by the outer sheath. The cable is high in interference characteristic, and ensures real-time and accurate digital signal transmission.
Description
Technical field
The present invention relates to the technical field of digital signal cable, a kind of cable for rail transit of specific design.
Background technology
At present urban track traffic is opened in existing a lot of cities, the whole nation, wherein, Beijing, Shanghai, San Ge city, Guangzhou in recent years every year newly-increased line length all reached 30 ~ 50 kilometers.In from now on 20 years, track traffic will be all the time in the high-speed developing period, and urban rail transit construction can not slowed down, and can raise speed on the contrary.The fast development of Line of Existing Railway, Line for Passenger Transportation, high-speed railway and urban track traffic, for the development of signal of communication technology provides new opportunity, supporting various types of communication signal cable is also widely applied with unprecedented scale with it.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cable for rail transit, and this railway cable can improve the anti-interference level of rail system.
In order to realize object of the present invention, technical scheme provided by the invention: a kind of cable for rail transit, comprise cable core, two layers of PET band, one deck PPD band, metallic sheath, hot-melt coating, inner cushion layer, steel-tape armouring and oversheath, it is characterized in that: described cable core is provided with two layers of PET band and one deck PPD band outward, described band is provided with metallic sheath outward, metallic sheath is covered with one deck hot-melt coating outward, described hot-melt coating is provided with inner cushion layer outward, inner cushion layer is wrapped steel-tape armouring outward, and steel-tape armouring is provided with oversheath outward.
Preferably, described cable core comprises many group star quads.
Preferably, described every group of star quad separates by entity insulated wire cores.
Beneficial effect of the present invention: realize the inspection of the omnidistance disconnected rail of track circuit, significantly reduced dead band, tuning differentiation road length, tuned cell disconnection fault and beat signal interference have been realized to inspection and protection, improved the anti-interference level of system, realize technical important breakthrough, on transmission security, had the raising of matter.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1-cable core, 2-two layers of PET band, 3-one deck PPD band, 4-metallic sheath, 5-hot-melt coating, 6-inner cushion layer, 7-steel-tape armouring, 8-oversheath, 9-star quad, 10-entity insulated wire cores.
Embodiment
A kind of cable for rail transit, comprise cable core 1, two layers of PET band 2, one deck PPD band 3, metallic sheath 4, hot-melt coating 5, inner cushion layer 6, steel-tape armouring 7 and oversheath 8, it is characterized in that: outer two layers of PET band 2 and one deck PPD band 3 of being provided with of described cable core 1, described band is provided with metallic sheath 4 outward, the outer one deck hot-melt coating 5 that is covered with of metallic sheath 4, the outer inner cushion layer 6 that is provided with of described hot-melt coating 5, the outer steel-tape armouring 7 of wrapping of inner cushion layer 6, the outer oversheath 8 that is provided with of steel-tape armouring 7, described cable core 1 comprises many group star quads 9, described every group of star quad separates by entity insulated wire cores 10.
Beneficial effect of the present invention: realize the inspection of the omnidistance disconnected rail of track circuit, significantly reduced dead band, tuning differentiation road length, tuned cell disconnection fault and beat signal interference have been realized to inspection and protection, improved the anti-interference level of system, realize technical important breakthrough, on transmission security, had the raising of matter.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
