Abstract
The utility model relates to an environment-friendly integrated signal cable for rail transit. The cable comprises a cable inner core and cable beltings, a shielding layer and an outer sheath layer arranged outside the cable inner core in sequence, and the cable inner core is constituted by a kind-5 winding, a kind-3 winding, an audio winding, and a control winding. The environment-friendly integrated signal cable for rail transit has the following beneficial effects: one cable has multiple uses; the cable is resistant to high temperature, can reach 200 DEG C, and can stand an aging test of 300 DEG C * 7H; the cable is resistant to low temperature, can reach minus 100 DEG C, and can be used in places of extremely low temperature; the cable has good mechanical performance, has a high cutting-resistant capacity, and the mechanical performance of insulation is greatly improved; the cable is good in flame retardancy, has high flame retardant performance, and can be applied to complicated high-temperature environments; and the cable has good shielding effects, the winding overlapping rate is more than 15%, and the shielding effect can reach 95% or above.
Description
Technical field
The utility model relates to a kind of fire resistant railway traffic signal cable, and particularly a kind of track traffic Environmental-protection comprehensive signal cable is the signal cable for subway, light railway.
Background technology
At present, 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 is to miniaturization, the future development such as lightweight, comprehensive simultaneously.The cable that is used for subway, light rail signal system mainly contains two kinds, be used for the cable of transmission of control signals and be used for the cable of transmission of audio signal, these two kinds of cables have adopted the low-smoke non-halogen flame-retardant structure, but all do not have the ability with cable transmission of control signals and audio signal.This series products external diameter is relatively large, and weight ratio is heavier, and shield effectiveness is poor, installs loaded down with trivial detailsly, 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 Environmental-protection comprehensive signal cable.
The utility model for achieving the above object, the technical scheme of taking is: a kind of track traffic Environmental-protection comprehensive signal cable, comprise cable inner core and the tape for cables that is provided with successively, screen and external sheath layer outside the cable inner core, it is characterized in that: described cable inner core is made of category-5 cable group, three class line groups, tone frequency channel wire group, control line group.
The beneficial effects of the utility model are:
1, multi-purpose has solved cable and can not realize problem with cable transmission of control signals, data-signal and audio signal with the same cable.
2, high temperature resistant: the ethylene-tetrafluoroethylene heatproof of sheath behind cross-linking radiation all can reach 200 ℃, can stand the ageing test of 300 ℃ * 7H.
3, 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.
[0009]4, 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 greatly improved the mechanical performance of insulation, and the intensity behind this kind material irradiation on average can reach 40Mpa.
5, 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.
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%.
