Metalspine segment

MetalSpine protective sleeve

Your cable is more vulnerable where it is visually exposed, especially where the cable enters/exits the trench. To protect the exposed cable we use a semi rigid heavy duty sleeve that is supplied in 2 halves and is 3mm thick. 

The number of segments ordered must be sufficient to cover and protect every part of the visible cable.


  • Can accommodate various cable sizes
  • Can be installed after cable installation – and even on live cables
  • Can be assembled to protect any required length.

Installing the MetalSpine sleeve:

  1. The halves of the sleeve are fastened  attached to the cable and loosely tightened
  2. The segments are interlocked and assembled until the whole cable is protected
  3. The segments are adjusted to fit the curve of the cable
  4.  The end that enters the switchgear, transformer or distrubution box  requires a specialised fitting which is used to secure the cable with  the supplied fittings. This fitting is ordered separately.
  5. The shear nuts are tightened until the nuts break off.
