NEW UK Competency Training Courses 50 x 50


Our new training centre is fully equipped to provide practical and theoretical training for jointers and engineers on all aspects of MV/LHV cable accessories. 

Within our new test lab, the accessories installed by candidates will be tested for AC withstand and partial discharge and in order to obtain a “pass”,  the tested installation should have pd levels <10pC.

Fully equipped with work benches and individual work stations complete with screen bushings and cable cleats, in order to replicate a realistic installation environment. 

Practical content

The starting point for most of our training courses is to ensure that the trainees are schooled in the art of cable preparation, which is essential for the correct installation of accessories.  Simple explanations of faults caused by poor cable preparation are given to make the trainees aware of why failures occur.

If preparation on a specific cable is required, please supply a sample for training purposes.

Theoretical content

These courses are designed to provide all attendees an introduction into the workings of cable accessories, the correct choice of accessory for a given application and most importantly the causes of failures and how to avoid them.

66 kv test lab


Successful candidates will be issued with a full 3 part certificate of competency comprising of a signed certificate, photo card and test report issued by a global cable manufacturer, which will be recognised and welcomed by numerous developers/network operators.
