Railway Signalling Cable - NR/PS/SIG/00005

Signalling cables play an essential role in ensuring the smooth running and reliability of the railway network, hence their unique specifications and design. They ensure the transmission of signals and a continuous power supply across all trackside signalling equipment applications. These cables are used for control and signal conveyance and keep the rail networks, with their passengers and cargo, moving safely.

Eland Cables offers a comprehensive range of Network Rail-approved signalling cables, with NR/PS/SIG/00005 specific applications designated by Type, and available in single, twin and multi-core varieties. Cables to this specification have an insulation which is either an elastomer or Low Smoke Zero Halogen (LSZH) type with tinned copper conductors. They have a voltage rating of 650/1100V and an operating temperature range of -25oC to +85oC.

Network Rail's standard NR/PS/SIG/00005 was formerly referred to as RT/E/PS/00005.

Railway Signalling Cable Selection

Our dedicated team of rail technical engineers have vast experience of working with Network Rail and its contractors on the selection of the right NR/PS/SIG/00005 cable. The team has been involved with the design and approval of this cable range and is very familiar with the cables' construction and their applications across the rail network. Separately, we are also able to assist with the specification of other rail signalling cables including the Westpac Co-Polymer cable for Invensys (Westinghouse) fail-safe signalling systems. Please contact us for more information on these cables and our wider range of rail power, rail OHL, and rail telecoms cables.
