TYPE A1, A2 & A3 Railway Signalling Cable

Application

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 are suitable for installation in ducts.

Standard

  • NR/PS/SIG/00005(formerly RT/E/PS/00005)
