详情描述

Railway signal 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) sheathed cables should not be below 0℃; polyethylene (PE) sheathed cables should not be below -20℃.

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

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