                        The Ring Main Unit solution



                        In the established market of containers and booming MV applications, shipbuilding companies need innovative solutions.

                          The Ring Main Unit solution 


                        • The Ring Main Unit solution combines all MV functional units to enable connection, supply and protection of one or two transformers on an open ring network.

                        Value Proposition

                        • OpEx reduction: length of HV cables reduced, shortening average ratio >30% for a configuration.
                        • Peace of mind: The new RM6 generation benefits from the accumulated experience acquired from the 850,000 functional units which equip electrical networks in more than 50 countries in America, Asia, Europe and Australia.
                        • Improvement of network maintainability and availability:
                          • A failed cable section on the HV loop can be disconnected.
                          • Automatic reconfiguration of the HV loop is possible after fault detection.

                        Differentiation Factors

                        • Optimised main HV switchboard footprint.
                        • Reduction of losses.
                        • Easy feeder segregation.
                        • Choice of' all-in-one units integrated in a single metal enclosure.
                        • Fast installation, fast cable connections on the front.
