1. The signal cable mainly refers to the special signal cable for railway, which is suitable for the control circuit of rated voltage AC 500V or DC 1000V and below to transmit railway digital signal, audio signal or automatic signal device.
2. Product technical standards:
● TB / T2476-1993 railway signal cable
● TB / T3100.1 ~ .5-2004 "Railway Digital Signal Cable"
● Q / JTL051.33-2001 comprehensive 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 transponder data transmission cable.
4. Railway signal cable characteristics:
The ambient temperature of the cable is -45 ~ + 60 ℃, and the ambient temperature for laying is not lower than -10 ℃. The long-term working temperature of the cable conductor should not exceed 70 ℃. The aluminum sheathed cable has good shielding performance, and the comprehensive sheath has certain shielding performance, and can be used for trunk lines in railway electrification sections or areas with strong electrical interference. The bending radius of the cable is not less than 15-20 times the outer diameter.
