South Wales Switchgear Retrofit Circuit Breakers

The Retrofit Process

The presence of aging switchgear like the South Wales C4X and D4X can result in issues with regards to reliability of equipment and the safety of your operators. GFF Power and P&B can offer a more cost-effective and time-efficient alternative to replacing or re-wiring entire panels for brand new switchgear.

Retrofit Process for South Wales Switchgear D4XD

Client's Existing Unit

Photographs are taken and scanning conducted at client’s premises

These scans are used to develop a 3D model of the existing unit

P&B use the millimetre accurate scan of the existing unit to create a 3D model of their retrofit design to match all key connection points

P&B use this model as the basis to manufacture their retrofit model to fit the client’s existing panel precisely

GFF Power partner with UK-based manufacturer, P&B. Operating out of their Manchester facility, P&B have been providing solutions for this worldwide problem for over 25 years and are global leaders in retrofit replacements for aging switchgear.

As a British company, P&B have done extensive work within the United Kingdom where South Wales Switchgear (SWS) including C4D and D4X models, has been one of the most common historical manufacturers of switchgear. With this being the case, it is no surprise that P&B are always confident in approaching South Wales Switchgear retrofit projects – even for models like C4X and D4X, and those which have been manufactured in Australia.

Innovative Design and Modelling Techniques

P&B have honed their retrofit methodology through experience and now make use of innovative design and modelling techniques to ensure absolute client satisfaction when the final product arrives on site. This includes 3D laser scanning and scan compilation for comparison with existing breakers, to ensure that any new retrofit is able to slot into existing panels seamlessly. The result of this is a refined and modern replacement.
