5 Reasons to Transition from SF6 to Pure Air in MV Switchgear

As electrification increases and renewable penetration grows, so too does the need for more medium voltage switchgear. This equipment commonly uses sulphur hexafluoride (SF6), a man-made gas with a very high global warming potential. The electricity industry invests in a more sustainable and digital future, and thus seeks green alternatives to SF6. Compared to other alternative gases for MV switchgear, pure air is quickly emerging as the superior choice. This paper explains why this particular MV technology is a superior choice for:

• • Environmental safety
  • Operational safety 
  • Ease of maintenance 
  • End-of-life treatment 
  • Functionality and performance
