Track connection cable

Abstract

The invention provides a track connection cable. The track connection cable consists of a mixed metal conductor (1), an insulator (2) and a protection sleeve (3), wherein the protection sleeve (3) and the insulator (2) cover the mixed metal conductor (1), so that the mixed metal conductor (1) realizes the signal transmission and power transmission of a regional automatic blocking system; the mixed metal conductor (1) is manufactured by stranding copper and steel materials; the protection sleeve (3) is a polyvinyl chloride (PVC) elastomer protection sleeve (3) or a polyurethane protection sleeve (3) and the like; the protection sleeve (3) is selected according to use conditions; and the structure of combining the insulator (2) and the protection sleeve (3) with the conductor ensures the performance of the track connection cable. The track connection cable of a high-speed line regional automatic blocking system can realize the simulation monitoring of the automatic blocking system when the speed of high-speed railway trains is 350km / h; the novel track connection cable has moisture resistance, corrosion prevention, low-temperature resistance, high-temperature resistance, wear resistance, fire resistance and the like; and the service life of the track connection cable is prolonged.

Description

technical field [0001] The invention relates to a connection cable, in particular to a track connection cable. Background technique [0002] The track connection cable developed in the prior art is usually a rope-like cable formed by twisting several or groups of wires. Each group of wires is insulated from each other and twisted around a center. The entire outer surface Although it is covered with a covering layer composed of a high degree of insulator, it is prone to moisture, prone to spontaneous combustion when used for a long time, easy to wear and tear during use, and cannot withstand high and low temperatures. Therefore, at this stage, the track connecting cables of the automatic blocking system of the high-speed railway line section are all imported from abroad, and there is no substitute product in China, and what is realized is the simulation monitoring of the automatic blocking system with a speed of 250 km / h. Contents of the invention [0003] In order to solv...
