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

Control circuit, where the composite sheathed railway signal cable possesses certain shielding properties, is 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 is suitable for use in environments with temperatures ranging from -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 cable with polyvinyl chloride (PVC) outer sheath should not be below 0℃; the cable with polyethylene (PE) outer sheath 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 is ≤0.8; the ideal shielding coefficient for the aluminum sheathed railway signal cable is ≤0.3.
