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.
For the eco-efficient switchgear portfolio, ABB has developed a new SF6-free load break switch based on a puffer interrupter technology. This new technology replaces the vacuum interrupter technology used in the C-module of SafeRing and SafePlus eco-efficient switchgear. The new load break switch will function both as a load break switch and disconnector switch, in one single operation. It will further be in series with a two-position earthing switch, which will simplify the operating sequence of the C-module.
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.
