Bonomi RMUs are a GIS (Gas Insulated Switches) metal enclosed for medium voltage applications (12 – 17.5 – 24 – 36 kV).
This technology guarantees excellent product performance and does not require maintenance, and is also indicated for insertion into ring networks with voltage up to 36 kV – 630 A – 20 kA and to power transformers of various voltages.
The RMU allows extensibility based on installation needs in addition to the possibility of remote control and activation.
