Area installation for 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 cable should not be below 0℃; the polyethylene (PE) sheathed cable should not be below -20℃.

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

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.
