Electrical cable is most vulnerable where it goes into and it leaves the trench. 95% of Cable theft occurs when the thief believes he can gain access to the cable where the channel or cable tray is visible.

Preventing the channels from being destroyed is difficult: thieves are tenacious and break concrete or use hack saws to saw through metal pipes to steal your cable.

We have a very unpleasant surprise for would-be cable thieves.

We now use advanced bank safe technology to protect electrical cables.

Carapax was created by using the technologies used in modern bank safes. 

Ultra High Performance Concrete is:

  • 14 times harder than concrete
  • 7 times harder to break and cut
  • thick enough to resist repeated attempts at destruction
  • armored with thousands of strands of fiber for extra strength
  • All housed in a channel that is thick enough to discourage even the most determined cable thief.

They said it is way over the top – but we are determined to keep your cable safe.
