Technical field
The utility model is related to data cable field, more particularly to a kind of track traffic copper-clad silver netting twine.
Background technology
Current China's track traffic industry is in the booming epoch, and railway transportation has started high speed, heavy loading
New upsurge, urban track traffic has also obtained great development.Therefore to track traffic cable, including power cable, data
The demand of transmission cable etc. also accordingly increases, it is generally the case that various adverse circumstances are experienced in track traffic in the process of moving,
Therefore requirement higher is proposed to electromagnetism interference, wearability, water proofing property of data transmission cable etc..
Utility model content
The utility model mainly solving the technical problems that provide a kind of track traffic copper-clad silver netting twine, with Gao Kang electricity
Magnetic disturbance, can guarantee that signal for a long time stablize, while having excellent waterproof, anti-wear performance.
In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of track traffic is provided to use
Copper-clad silver netting twine, including：Copper-clad silver powder conductor, PE insulating layer of conductor, screen layer and thickening PVC sheath, the screen layer are used
Three-layer composite structure, including：Copper cover aluminum gauze screen and the aluminium film for being pressed together on the copper cover aluminum gauze screen surfaces externally and internally, the PE lead
Body insulating barrier is coated on outside the copper-clad silver powder conductor and constitutes heart yearn with the copper-clad silver powder conductor, and the heart yearn has 8, two
Two four pairs of twisted-pair feeders of stranded composition, the screen layer is coated on outside four pairs of twisted-pair feeders, and the thickening PVC sheath is coated on institute
State outside screen layer.
In one preferred embodiment of the utility model, a diameter of 0.55-0.58mm of the copper-clad silver powder conductor.
In one preferred embodiment of the utility model, the wall thickness for thickening PVC sheath is 1.2-1.8mm.
In one preferred embodiment of the utility model, the lay of four pairs of twisted-pair feeders is respectively：7mm、8mm、
8.5mm、9mm。
The beneficial effects of the utility model are：The utility model uses copper-clad silver powder conductor, with resistance is low, signal transmission
By force, the characteristics of signal transduction is remote, inoxidizability is strong, while using the screen layer of three-layer composite structure, it is ensured that the anti-electromagnetism of netting twine is done
