Working Conditions
1. Ambient temperature when working: -40℃ ~ 60℃
2. Max. working temperature of conductor: 70℃ for long-term application
3. Min. ambient temperature when laying: 0℃ for PVC outside sheathed type, and -10℃ for PE outside sheathed type.
4. Min. bending radius: 10 times of cable outer diameter for non-armored type, and 15 times of outer diameter for armored type.
5. The combined sheath and aluminum sheath offer shielding effect which makes our railway signal cable suitable for places that require shielding cable.
