The Retrofit Process
Aging switchgear including the Brush/Hawker Siddeley VSI R4 can cause reliability and safety problems in medium voltage work environments, potentially risking harm to both plant and personnel. Fortunately, P&B and GFF Power can provide an economical and unobtrusive alternative to the array of changes required for new switchgear installations.
Retrofit Process for Brush/Hawker Siddeley VSI R4
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 VSI 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
Our Retrofit Switchgear supply partner, P&B, have been manufacturing low-impact designs including VSI retrofits to tackle this issue for nearly 30 years from their factory in Manchester, UK. As a result, they are widely considered a world-wide authority when it comes to retrofitting for modern switchgear requirements.
As with many OEMs of switchgear equipment in Australia, Brush/Hawker Siddeley has its roots in the United Kingdom, where a significant amount of their equipment, including the VSI has been installed and is now coming to the end of its intended lifespan. Given this, P&B are very familiar with the common retrofit requirements for Brush/Hawker Siddeley circuit breakers and have a wealth of experience with this manufacturer, both at home and abroad.
A refined process
Through years of rigorous research, testing and development, P&B have refined their retrofit processes (from first concepts through to manufacture), utilising modern laser scanning and 3D modelling techniques to maximise the accuracy with which their retrofit models match your existing on-site panel. The result: minimal to no on-site adjustments required.
P&B can offer Brush/Hawker Siddeley Switchgear retrofit designs for the following ratings and models:
3.3kV, 6.6kV, 11kV and 12kV
400A, 630A, 800A, 1250A and 2000A
20kA, 25kA, 31.5kA
75kV or 95kV
Available Brush/Hawker Siddeley Models:
VSI (R4 & R8 etc.), VMV, VMH
P&B are always striving to improve their retrofit range and capabilities through research and development – please contact us with your requirements to discuss the possibilities for retrofit of your Brush/Hawker Siddeley circuit breakers.
