Railway signaling cables are suitable for transmitting railway signals, audio signals, or automatic signal devices at rated voltages of AC 500V or DC 1000V and below.

Control circuit, where the integrated sheath railway signal cable has certain shielding properties, suitable for electrified sections or other areas with strong electromagnetic interference.

Installation in areas prone to electrical interference.

1. Usage Features

1.1 The cable's operating temperature range is -40℃ to +60℃.

1.2 The long-term working temperature of the cable conductor should not exceed +70°C.

1.3 Cable Laying Environmental Temperature: The polyvinyl chloride (PVC) outer sheath cable should not be below 0℃; the polyethylene (PE) outer sheath cable should not be below -20℃.

1.4 Allowable Bend Radius for Cable: Non-armored cable should be no less than 10 times the cable outer diameter; armored cable should be no less than 15 times the cable outer diameter.

1.5 The ideal shielding coefficient for the overall sheathed railway signal cable should be ≤0.8; for the aluminum sheathed railway signal cable, the ideal shielding coefficient should be ≤0.3.
