Rail web Permanent Electrical Contact
CodeAR67

for hole diameter 8 - 8,5 mm

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
