The names of Whipp & Bourne, Brush and South Wales Switchgear are synonymous with circuit breaker technology around the globe. All companies have a history which can be traced back over 125 years and it’s a background which cannot be ignored even though the demands of today’s industrial and power distribution sectors are vastly different and more complex. Today they form part of Hawker Siddeley Switchgear Ltd. - part of Melrose plc.
As a major national and international manufacturer of a range of distribution switchgear, Hawker Siddeley Switchgear Ltd serves not only electrical utilities worldwide but also a vast array of industrial and transit sectors where the need for safe and reliable power supplies is paramount.
With a highly-skilled workforce and manufacturing facilities both in the UK and Australia, a technology centre based in the UK and sales offices around the globe, we have maintained a global reach - building on a clear and unrivalled reputation for innovation. The success of the original companies was rooted in an ability to pioneer ground-breaking technologies, introducing state of the art developments which still lead the way in the switchgear sector.
Hawker Siddeley Switchgear Ltd remains committed to innovation, striving to provide what our customers could have - not just what they want.
PROVIDING GLOBAL SWITCHGEARSOLUTIONS

The father of modern switchgear, Hawker Siddeley Switchgear Ltd’s world renowned GVR Recloser was the first in a range of equipment utilising one of the most advanced operating mechanisms available on the market today – Hawker Siddeley Switchgear’s ‘Fit & Forget’ Technology, featuring the award winning magnetic actuator.
The GVR provides ‘intelligent control’ and protection on power distribution networks, whilst offering a lifetime of trouble-free service.
The GVR automatic recloser is now available as a tank only option for those customers who wish to connect their own protection and control cubicles. Alternatively, customers looking for a ground-mounted solution can select our epoxy separable bushings for cableconnected networks.
GVR RECLOSER: FOR POLEMOUNTING AND SUBSTATIONAPPLICATIONS

■ Superior, proven ‘Fit & Forget’ technology with minimal maintenance■ The patented, single coil magnetic actuator mechanism allows the GVR to operate
independently of the MV supply■ Environmentally friendly vacuum interruption produces no by-products■ The lightweight corrosion resistant aluminium tank makes the GVR easier to transport and install■ The EPDM or silicone bushings are tested for tracking and erosion to IEC 61109 and are resistant to damage from vandalism or mishandling■ Endurance tested to 10,000 operations■ Pole mounted or substation mounted, the GVR can be integrated into the most advanced distribution automation schemes, or can operate as a stand-alone recloser■ By using the advanced control and protection functions of the Panacea, the GVR can
also be used in applications where reclosers have not traditionally been used such as closed rings and underfrequency load shedding schemes
■ The 3-in-1 Recloser – the GVR can be configured to function as a Switch, Sectionaliser or Recloser by using one of the specially pre-engineered protection and control cubicles
KEY FEATURES
08 08
The GVR has a wide range of applications:
■ Pole mounted applications■ Substation applications■ Wind Farm applications■ Switch applications (Auto-reclosing)■ Sectionaliser applications
With over 25,000 GVR auto-reclosers in service, the “father of modern switchgear” has proved its worth time and time again as a stellar product.
A product that was at the forefront of technology 20 years ago still holds its own today, in a very competitive market.
