Tensorex C+ Automatic Tensioner

The patented, automatic tensioning system that uses the force of a coil spring to constantly tension the railway catenary and/or bearer cable. It effectively compensates the expansion and contraction caused by fluctuating daytime and nighttime temperatues and seasonal changes. The system:

  • is very compact and fast to install
  • frees space around support structures and reduces the chances of vandalism
  • is maintenance free
  • provides a constant force with very little hyteresis
