Cable And Accessories

cable testing

We are very experienced in the testing of parent cable, joints and terminations and have developed facilities specifically for the more frequently required tests (e.g cable joint thermal cycling under a 1m head of water).  In recent years we have tested a range of different designs of cable including extruded polymeric, PILC, mass impregnated and fluid filled.  Distribution cables, submarine fibre optic cables and neutrally bouyant cable systems have been assessed.

As well as testing new sytems we also have been involved in forensic investigation of cables and accessories that have failed in service - for more details please see forensics.
