Railway Cables
Railway Signalling & Control Cables Railway Telecom Cables Railway Power & Control Cables FIRERAIL Traction Cables





The cables are used as balise cables for ERTMS (European Rail Traffic Management System) railway networks.

The cables are armoured and can provide low reduction factor.
