The signal cable disclosed by the utility model has the beneficial effects that: the signal cable is high-temperature-resistant and low-temperature-resistant; the signal cable is small in outside diameter, light in weight, good in mechanical properties and good in flame resistance; a soft cable is easy to lay and install; and the shielding effect can reach more than 95%.
Description
Technical field
The utility model relates to a kind of cable, and particularly a kind of track traffic is with the high temperature resistant microlight-type of anti-irradiation signal cable.
Background technology
Along with the develop rapidly of novel rail and electronics industry and defence engineering, the cable of signal transmission usefulness is proposed higher requirement, cable develops to miniaturization, direction such as in light weight, high temperature resistant.General high temperature resistant signal cable adopts fluorine materials such as perfluoroethylene is third rare, polytetrafluoroethylene as insulating material, insulate for extruding clad structure, and this series products external diameter is relatively large, and weight is heavier, and shield effectiveness is poor, can not satisfy the requirement of novel rail.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of track traffic with the high temperature resistant microlight-type of anti-irradiation signal cable.
The utility model is for realizing above-mentioned purpose; The technical scheme of being taked is: a kind of track traffic is with the high temperature resistant microlight-type of anti-irradiation signal cable; Comprise inner wire, insulating barrier, screen, restrictive coating, outside said inner wire, be provided with one deck cross-linking radiation ethylene-tetrafluoroethylene insulating barrier, copper strips screen, cross-linking radiation ethylene-tetrafluoroethylene restrictive coating successively.
The beneficial effect of the utility model is: 1, high temperature resistant: because inner wire has adopted the silver-plated copper conductor; Often heatproof can reach 200 ℃; Insulating barrier and restrictive coating have all adopted the cross-linking radiation ethylene-tetrafluoroethylene; Ethylene-tetrafluoroethylene heatproof behind cross-linking radiation all can reach 200 ℃, can stand the ageing test of 300 ℃ * 7H.Low temperature resistant: the temperature that works long hours of cross-linking radiation ethylene-tetrafluoroethylene insulating material can reach-100 ℃, can be used for the place of limit low temperature.
2, external diameter is little, in light weight: inner insulating layer thickness only has 0.10mm, restrictive coating thickness that 0.10mm is also only arranged, and the density of ethylene-tetrafluoroethylene insulating material is 1.7g/cm
3, and the density of other fluorine materials is generally 2.1 g/cm
3, to reduce about 40% than the weight of common fluoroplastics hookup wire.
3, good mechanical property: the intensity of this kind of cross-linking radiation ethylene-tetrafluoroethylene material is very high, has the very high anti-ability of cutting, and has improved the mechanical performance of insulation greatly, and the intensity behind this kind material irradiation on average can reach 40Mpa.
4, good flame resistance: adopt the oxygen index of this kind of cross-linking radiation ethylene-tetrafluoroethylene material can reach 40, have very high fire resistance, can be applied to complicated hot environment.
5, softness: because conductor has adopted the stranded formation of the superfine silver-gilt copper wire of 0.08mm, so improved the flexibility of cable greatly, cable is easy to laying installation.
6, shield effectiveness is good, uses copper strips as screen, and the wrapped rate of putting up is more than 15%, and shield effectiveness can reach more than 95%.
