The Future of British Switchgear
Sulphur hexafluoride (SF₆) is one of the most potent greenhouse gases in use today, with a global warming potential approximately 24,300 times greater than carbon dioxide (CO₂) over a 100-year period. Despite being used in relatively small quantities, its environmental impact is significant. It is one of the 6 notified greenhouse gases in the F Gas regulations. Across Great Britain, electrical switchgear is estimated to contain around 1 million kg of SF₆ , spread across more than 200,000 units . Approximately 97% of these assets operate at distribution level , within medium and high voltage networks. For decades, SF₆ has delivered compact, reliable switchgear. Why SF₆ Became the Standard SF₆ offers unrivalled electrical insulation and arc‑quenching performance, allowing high-energy switching…
