TYPE D1 & D2 Railway Signalling Cable

Application

The TYPE D1 & D2 Railway Signalling 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& BS 6360.

Insulation
LSZH or EPR Type GP4 to BS 7655.

Core Wrapping
Plastic tape(s) with overlapping.

Sheath
LSZH.
