SafeRing Air SafePlus Air 24kV - Medium Voltage Switchgear Gas Insulated

SafeRing & SafePlus

Bridging Tradition and Innovation with SF6 and SF6-Free Technology

Compact gas-insulated switchgear for all applications in secondary power distribution

ABB’s gas-insulated switchgear portfolio for secondary distribution includes the SafeRing, ring main unit (RMU), and SafePlus switchgear platform designed for all indoor and outdoor applications including high altitudes (higher than 1500 m above sea level) and harsh weather conditions. Both switchgear solutions are fully compliant with IEC standards.

SafeRing/SafePlus also offer an SF6 (sulfur hexafluoride) -free variant, called SafeRing Air/SafePlus Air, with dry air as the insulation medium and fully compliant with the IEC standards and the EU F-gas regulation (EU) 2024/573. The SF6-free versions are designed with the same interface, footprint, and operations as the original SafeRing and SafePlus switchgear.

Since 1967, ABB has been delivering gas-insulated (GIS) switchgear. As we continued to innovate, in 2013 we launched our SF6-free GIS for secondary distribution. Our next generation of SF6-free switchgear solutions, using dry air and natural origin gas technology for 24 kV and above applications is now coming to the market.
