The signal cables are divided into: railway signaling cable, PVC insulated signal cables, control signal cable, mining signal cable

Railway signal cables use: apply to the control circuit of the rated voltage of AC 500V or DC 1000V and below transmission railway signal, audio signal or automatic signaling devices, which jacket, aluminum sheathing, railway signaling cable shield performance, suitable for electrification section or other areas of strong radio interference laying.
Use the features:
Cable (1) the use of an ambient temperature of -40 ° C ~ +60 ° C
(2) long-term operating temperature of cable conductor should not exceed +70 ℃.
(3) cable laying ambient temperature: PVC sheathed cable should not less than 0 ° C; polyethylene outer sheath cable should not be less than -20 ℃.
(4) cable allows the bending radius: non-armored cable shall be not less than 10 times the cable diameter; armored cable should not be less than 15 times the cable diameter.
(5) the jacket railway signal cables ideal for shielding factor of ≤ 0.8; aluminum sheath railway signal cables ideal shielding factor of ≤ 0.3
