Rail web cable connection applications:
- Traction return bonding
- Continuity bonding
- Signal track circuit connection
- Ground bonding
This unique system was designed and developed by Cembre in 1988 following a review of existing electrical connection systems.
The aim of the Cembre system is to provide a low resistance interface between the rail web and the terminal lug.
Following in-depth testing in the laboratory and extensive fi eld trials, the system has been recognised and approved for total reliability.
- low electrical resistance (microhm)
- simple to install, not dependent on operator skill level
- quick and easy to install (less than one minute)
- easy to connect/disconnect cables, for fault finding
