11kV Switchgear Life Extension

11kV Switchgear Extensions, Retrofits & Upgrade Projects

11kV Switchgear Life Extension & Project Specialists

Good quality, well maintained, 11kV switchgear should perform safely and reliably for 40+ years and thousands of switching operations. However OEMs often quickly withdraw support for their legacy equipment, preferring instead to replace legacy gear with their newest product. This is often not necessary.

With almost 100 years of switchgear engineering experience and unrivalled experience across the breadth of UK manufactured and installed 11kV switchgear types, we offer industry leading engineered solutions for extending and managing the life of 11kV switchboards, achieving:

Cost Savings &
Improved ROI

Minimal Downtime
& Disruption

Adherence to
Current Standards

Eco-friendly Resource
Efficiency

Our knowledge of every major UK installed OEM’s types means that we are widely acknowledged as one of the UK’s leading authorities on legacy 11kV switchgear – major OEMs regularly consult us for advice about their legacy equipment.
