Secondary GIS
Secondary gas insulated switchgear has been subject to a significant development in the past 20 years, resulting in increased functionality and smaller dimensions. ABB's Ring Main Units (RMUs) and secondary switchgear are prepared for the use in future distribution grids and designed for use in various applications such as compact secondary substations, light industry, renewables or infrastructure.
Portfolio overview
SafeRing
- Global main line RMU solution up to 40,5kV
- Optimized for standard RMU applications: Select SafePlus switchgear for more options
- Completely sealed system
