Railway signal cables English Name: Railway the signal cable definition: railway signaling cable Product Description A railway signal cables: Applies to the rated voltage of AC 500V or DC 1000V and below transmission railway signal, audio signal or automatic signaling devices, control circuits, which jacket, aluminum sheath railway signal cables have a certain shielding performance, suitable for electrified section or other laying regions of strong radio interference. Second, the use of features: (1) Cable to use an ambient temperature of -40 ° C ~ +60 ° C (2) long-term operating temperature of cable conductor should not exceed +70 ℃. (3) Cabling ambient temperature: PVC sheathed cable should not less than 0 ° C; polyethylene outer sheath cable should not be less than -20 ℃. (4) Cable 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) Integrated sheath railway signal cables ideal shielding factor of ≤ 0.8; aluminum sheath railway signal cables ideal shielding factor of ≤ 0.3, the delivery length of 500m and above the cable should not less than 50% of the length of the total deliveries; 50 ~ 250m the short section of cable delivery length should not exceed 5% of the total length of delivery; cable length measurement error should not exceed ± 0.5%.
