Railway signal cable
Usage:
It is used in rated voltage up to AC 500V or DC 1000V control circuit as railway signal transmission and communication,audio signal or automatism signal,the multi-sheath railway signal cable has screen character,which is suitable for laying in electrified railways or others field under strong Interference.

Usage Feature:
1.1 The ambient temperature :-40 deg.~+60 deg.
1.2 the operating temperature should not be higher than +70deg.
1.3 The ambient temperature under installation ,PVC sheath cable should not be below 0 deg.,PE sheath cable should not be below -20 deg.
1.4 mini bending radius: non-armoured cable>=10 times of the cable diameter     armoured cable>=12 times of the cable diameter
1.5 multi-sheath train signal cable screening factors <=0.8  aluminium sheath train signal cable screening factors <=0.3
