Gas-insulated compact switchgear SafePlus Air

Compact medium voltage (MV) gas-insulated switchgear (GIS) for secondary distribution, 12 kV, 630A

SafePlus Air is a metal enclosed compact switchgear system for up to 12 kV distribution applications. The SafePlus Air portfolio is based on dry air technology as insulation medium. Dry air insulation has a Global Warming Potential (GWP) of zero.

The switchgear design is based on the existing SafePlus portfolio, offering an advantage to the end users with the same user interface, footprint, spare parts and operation. The switchgear has a unique flexibility thanks to the possible combination of fully modular and configurations.

SafePlus Air is a completely sealed system with a stainless steel tank containing all live parts and switching functions. A sealed steel tank with constant atmospheric conditions ensures a high level of reliability as well as personnel safety and a virtually maintenance-free system.
