Energy storage label for ring main unit

What is a ring main unit?

Though RMUs are integral to ring network configurations, their utility extends far beyond. Load switch-based high-voltage switchgear has become increasingly prevalent across non-ring distribution systems; hence, the term “Ring Main Unit” has become widely applied to any high-voltage cabinet that predominantly utilizes load switches.

Why are ring main units important?

When it comes to delivering electricity to people, it's crucial that the process is efficient, dependable, and safe. That's why Ring Main Units (RMUs) have become essential in medium voltage distribution networks. They offer compact and adaptable ways to distribute power.

What should I consider when configuring a ring main unit (RMU)?

When configuring a Ring Main Unit (RMU), some key parameters to consider are: The suitable voltage level to meet the requirements of the specific network. The maximum load that the RMU can handle without compromising performance. The ability of the RMU to withstand and interrupt fault currents.

What is a tower ring main unit?

Fast Installation A tower ring main unit integrates gas insulated switchgear, protection, and transformer functions compactly within the tower structure. This modular design allows quick on-site assembly and commissioning for reduced downtime and installation costs.

How does a distribution ring work?

Each distribution branch in this ring can draw power from both sides of the loop for continuity even if one segment fails, providing redundancy similar to dual feed systems but from a singular source.
