A Ring Main Unit (RMU) is a type of electrical switchgear commonly used in medium-voltage distribution systems. It is designed to control, protect, and isolate electrical circuits, ensuring a reliable power supply in distribution networks. RMUs are often found in urban areas, industrial sites, and renewable energy systems, where they manage power flow and help maintain the stability of the grid by isolating faults and enabling load management.

A Ring Main Unit (RMU) is a key component used in medium-voltage power distribution systems. It is designed to control, protect, and isolate electrical circuits, ensuring a reliable supply of electricity across various applications. RMUs are particularly useful in ring-type distribution networks, allowing power to flow from multiple directions, which enhances the stability and resilience of the grid.
