Problems solved by technology
[0003] Due to the complex and changeable environment along the railway, the railway signal cable needs to pass through the electrified section or be laid in other areas with strong electrical interference, which not only requires the railway signal cable to have better anti-interference ability, but also requires high toughness and bending resistance Flexibility and anti-extrusion recovery performance, but ordinary railway signal cables can not meet the requirements very well

The invention discloses a railway signal cable, which comprises an external protective jacket, a shielding net cover, an isolating protection layer, a plurality of conductive core bodies, insulating sleeves and a support core body, wherein the external protective jacket is arranged outside the shielding net cover; the shielding net cover is arranged outside the isolating protection layer; the plurality of conductive core bodies are symmetrically arranged inside the isolating protection layer; the insulating sleeves are respectively arranged outside the plurality of conductive core bodies; the support core body is arranged at the center position of the plurality of conductive core bodies; and connection materials are respectively arranged between the insulating sleeves and the support core body. In the manner, the railway signal cable disclosed by the invention is firm in structure, good in interference shielding property, high in tenacity and bend-resistant; the internal conductive core bodies are not wound, are accurate to locate and can be recovered quickly after being extruded; the signal transmission stability is good; and the service lifetime is long.
Description
technical field [0001] The invention relates to the field of signal cable design, in particular to a railway signal cable. Background technique [0002] The cable is usually composed of several wires or groups of wires, each group of wires is insulated from each other, and the entire outer surface is covered with a highly insulating covering layer, which has the characteristics of internal electrification and external insulation. According to the application, the cables are divided into power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mine cables, aluminum alloy cables and so on. Due to the rapid development of high-speed railways, the market demand for railway signal cables has risen sharply. Railway signal cables are suitable for transmission of railway signals, audio signals or control circuits of automatic signal devices with a rated voltage ...
