Rigid overhead conductor rail CR4
The innovative rigid overhead conductor rail system for speeds of up to 250 km/h
The innovative rigid overhead conductor rail system for speeds of up to 250 km/h
Our rigid overhead conductor rail system is an innovative solution for traction current systems, characterised by its low height and high electrical cross-section, avoiding the need for additional feeders. Particularly suitable for tunnels, it allows for smaller tunnel cross-sections and the electrification of older tunnels. The system’s versatility means it can also be used in maintenance workshops and loading facilities, and on mobile bridges and open tracks.
Our rigid overhead conductor rail system offers high operational safety, high fire resistance, and low maintenance requirements. The overhead conductor rail can be connected directly to the contact wire of catenary overhead contact lines and integrated into existing overhead contact line systems. The system supports various operating voltages and is designed for speeds of up to 250 km/h in accordance with EN 50367.
With over 6,600 kilometres of track installed in more than 30 countries, the system offers proven reliability and efficiency.
