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. Not only the railway signal cable is required to have better anti-interference ability, but also high tensile performance and Bending resistance, but ordinary railway signal cables cannot meet the requirements very well, and further improvement is needed

Abstract

The invention discloses a bend-resistant railway signal cable, which comprises an external protective jacket, an interference shielding sleeve, an isolating winding sleeve, a plurality of round stiffeners, insulating sleeves and a plurality of conductive core bodies, wherein the external protective jacket is arranged outside the interference shielding sleeve; the isolating winding sleeve is arranged inside the interference shielding sleeve; the plurality of conductive core bodies are evenly distributed inside the isolating winding sleeve; the insulating sleeves are respectively arranged outside the plurality of conductive core bodies; and the plurality of round stiffeners are respectively arranged in the isolating winding sleeve. In the manner, according to the bend-resistant railway signal cable disclosed by the invention, through the addition of the plurality of round stiffeners, the overall structural strength is increased; particularly the tensile property and the bending resistance are improved; a close connection between the insulating sleeves is strengthened; and the bend-resistant railway signal cable is long in service lifetime and relatively good in anti-interference performance.

Description

technical field [0001] The invention relates to the field of signal cable design, in particular to a bending-resistant 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 wit...
