Signalling Control Railway Cables

We are offering signalling control railway cables.
Application
the cables are used as cabling wires for the relays and electronic equipments in the traffi c control center and trackside equipment shelter. The cv cables are suitable for use only in optical control panel (ocp) wiring.
