NPA Training with People Training Image





Our new training centre is fully equipped to provide practical and theoretical training for jointers and engineers on all aspects of medium voltage cable accessories.  Each course is individually designed to meet the specific requirements of our clients.


Nexans Power Accessories (UK) Ltd training centre is located in Castleford, West Yorkshire, WF10 2JA.


The training centre is fully equipped with work benches and tools for ten trainees.  In addition a projector is used for theoretical presentations.

Practical courses

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

After the trainees have satisfied the trainers of their competence with regard to cable preparation the course can be tailored to suit individual clients.  Instruction on all types of accessory can be provided.  These accessories can be heat shrink, cold shrink and push-on cable terminations and joints. In addition a full fault analysis service is provided.

If preparation on a specific cable is required, please bring a sample for demonstration purposes.

Theoretical Courses

These courses are designed to give engineers 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.


Successful candidates will be issued with a certificate, which will be recognised & welcomed by numerous developers/network operators.
