Railway Signal Cable

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

Area laying for electrical interference.

1. Features Usage

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 PVC outer sheath cable should not be lower than 0℃; the polyethylene outer sheath cable should not be lower than -20℃.

1.4 Allowable Bend Radius for Cable: Unarmored cable should not be less than 10 times the cable outer diameter; armored cable should not be less than 15 times the cable outer diameter.

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