- The cables are designed for railway signalling systems. The cables are suitable for use in d.c. circuits where the nominal voltage to earth does not exceed 1100 volts and installation in ducts.
Standards :
- NR/PS/SIG/00005(formerly RT/E/PS/00005)
Construction :
- Conductors : Tinned stranded copper, according to IEC 60228 class 2& BS6360.
- Insulation : LSZH or EPR Type GP4 to BS7655.
- Core Wrapping :Plastic tape(s) with overlapping.
- Sheath : LSZH.
