SF6 Free Switchgears

Dry-air gas insulated switchgear for 24 / 36 kV — all the compactness of GIS without SF6, the strongest greenhouse gas.

The switching devices of all poles are enclosed in a sealed metal vessel filled with dry air — non-toxic, non-flammable, chemically neutral and climate-neutral. There is no F-gas handling, reporting, certification or end-of-life disposal cost.

  • Sealed pressure system designed for at least 30 years, maintenance free
  • Cable compartment, current and voltage transformers accessible from the front
  • A panel can be replaced without moving the others or any gas work
  • Optional intelligent sensors for real-time switchgear health monitoring
  • AFLR internal arc classification, LSC-2, PM partition class, logical interlocks to IEC 62271-200
