Overview

Signal cable is a signal transmission tool. The signals transmitted by general signal cables are very small. In order to avoid interference, signal cables have a shielding layer that wraps around the conductor, usually made of conductive cloth, woven copper mesh or copper foil (aluminum). The shielding layer needs to be grounded, and external interference signals can be introduced into the ground through this layer to prevent interference signals from entering the inner conductor and reduce the loss of transmission signals.

TB/T3100.1～.5-2004Railway Digital Signal Cable

Q/JTL051.33-2001Integrated shielded signal cable

3.The main models are:

Railway signal cable, railway comprehensive sheathed signal cable, railway aluminum sheathed signal cable, railway digital signal cable, railway shielded digital signal cable, railway axle counting signal cable, railway responder data transmission cable.

4.The ambient temperature for the use of railway signal cables is-45～+60℃The ambient temperature for laying shall not be lower than-10℃. The long-term operating temperature of cable conductors should not exceed70℃. Aluminum sheathed cables have good shielding performance, and the comprehensive protective layer has certain shielding performance, which can be used for mainline or strong electrical interference areas in railway electrification sections. The bending radius of the cable shall not be less than the outer diameter15－20Twice.
