Description
Technical field
The utility model relates to a kind of subway cable.
Background technology
At present, the subway cable mostly using, its safe anti-detection, the performance such as anti-interference do not have safety assurance.So be badly in need of pushing away the anti-detection cable of new a kind of radiation proof, the specification requirement of its property can be guaranteed in use often to need mobile, therefore withstand voltage to it, ageing-resistant, acid and alkali-resistance, waterproof high temperature resistantly waits instructions for use higher.And common cable product exists potential safety hazard as signal transmission and transmission power supply, on the other hand, these electric wires that are bundled in one are subject to extraneous interference, and poor anti jamming capability affects signal transmission, and distortion rate is high.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of and adopted multicore, by anti-ectocine and withstand voltage, the ageing-resistant cable designing.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of subway cable, comprise conductor, insulating barrier, outer reinforcement synthetic fibre body, screen and interior reinforcement synthetic fibre body, described conductor adopts the naked soft tinned copper conductor of the 5th class that meets national standard, it is characterized in that: described screen is coated on conductor and the interior reinforcement synthetic fibre volume surrounding of multiply after wrapped, described screen is magnetic expanded material, gap between foam filled outer reinforcement synthetic fibre body and conductor, described screen skin is outer reinforcement synthetic fibre body, described outer reinforcement synthetic fibre volume surrounding is insulating barrier, described flame-retardant layer is at the skin of insulating barrier, described flame-retardant layer is low smoke and zero halogen material.
As a kind of improvement, described conductor is that mode is twisted in sub-thread bundle strand and layering again.
As a kind of improvement, described insulating barrier adopts low-smoke non-halogen flame-retardant crosslinking polyolefin elastic body material.
Owing to having adopted technique scheme, compared with prior art, the utlity model has by anti-ectocine and withstand voltage, ageing-resistant, improved the physical life of cable and the accuracy of signal transmission, reduced cost.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
accompanying drawing explanation
Fig. 1 is the cross section view of a kind of embodiment of the utility model.
In figure: 1-insulating barrier; 2-strengthens synthetic fibre body outward; In 3-, strengthen synthetic fibre body; 4-screen; 5-conductor; 6-flame-retardant layer.
Embodiment
Embodiment:
As shown in Figure 1, a kind of subway cable, comprise conductor 5, insulating barrier 1, outer reinforcement synthetic fibre body 2, screen 4 and interior reinforcement synthetic fibre body 3, described conductor 5 adopts the naked soft tinned copper conductor 5 of the 5th class that meets national standard, it is characterized in that: described screen 4 is coated on conductor 5 and the interior reinforcement synthetic fibre volume surrounding 3 of multiply after wrapped, described screen 4 is magnetic expanded material, gap between foam filled outer reinforcement synthetic fibre body 2 and conductor 5, described screen 4 skins are outer reinforcement synthetic fibre body 2, described outer reinforcement synthetic fibre volume surrounding 2 is insulating barrier, described flame-retardant layer is at the skin of insulating barrier, described flame-retardant layer is low smoke and zero halogen material.
In the utility model, described conductor 5 twists mode, described insulating barrier 1 employing low-smoke non-halogen flame-retardant crosslinking polyolefin elastic body material again for sub-thread bundle strand and layering.
Conductor 5 adopts the naked soft pure soft tinned copper conductor 5 of the 5th class that meets national standard, guarantee that electric conductivity is more superior, and cable in use has higher flexibility, crooked extension property easy to use.
Cable insulation 1 adopts low-smoke non-halogen flame-retardant crosslinking polyolefin elastic body (TPUR) material, and finished product, after cross-linking radiation, fully improves the physical and mechanical properties such as high temperature resistant, the low temperature, oil resistant, acid and alkali-resistance, fire prevention of cable, wear-resistant, waterproof.
Screen 4 is expanded material, and the gap between foam filled outer reinforcement synthetic fibre body 2 and conductor 5 has not only reached the effect of restrainting nearly conductor and also taken shielding external disturbance to, has guaranteed the stable of signal transmission.
Flame-retardant layer 6 in the utility model, prevented when cable is burned can by flame spread control within the specific limits, therefore can avoid because ignition of cable prolongs the disaster that combustion causes, thereby improve the fire prevention level of cable line, saved cost.
The utility model is strengthened being used in conjunction with of synthetic fibre body and interior reinforcement synthetic fibre body at home and abroad, can improve significantly resistance to pressure and the resistance to ag(e)ing of cable, has improved the useful life of cable and the accuracy of signal transmission.
