Organization: NR
Publication Date: 4 March 2017
Status: active
Page Count: 20
scope:

Cables specified in this standard are intended for use in signalling power distributions systems where the nominal voltage is up to 650 V a.c. and where the electrical systems are either TN or IT.

This specification details the construction and test requirements for armoured and enhanced unarmoured copper and aluminium multicore core cables intended to be used in signalling power distribution systems covering a range of nominal conductor cross-sectional areas. The specification details the requirements for stranded copper and stranded or solid aluminium conductors.

The specification details the requirements for armoured cable having a PVC sheath and unarmoured cable with enhanced sheath and insulation thickness. Both cable types are specified with options for a sheath with low emission of smoke and corrosive gases when affected by fire. This specification also details security, water blocking and rodent protection requirements.

Purpose

This specification defines cable construction and performance requirements for signalling power distribution cables to be used in railway signalling systems.

NOTE: The implementation of this standard provides risk management of low quality cable being manufactured and introduced into the infrastructure that may give rise to electric shock, fire or performance risks
