RMUs

Ring Main Units (RMUs)

Hunter Transformers supplies Ring Main Units (RMUs) that provide safe, reliable, and flexible switching solutions for medium voltage power distribution networks. RMUs are a critical component in ensuring continuity of supply, offering the ability to isolate and protect sections of the network while maintaining service to downstream loads. Compact in design yet robust in performance, our RMUs are ideally suited for use in renewable energy projects, utilities, industrial operations, and urban infrastructure where efficiency and safety are paramount.

Our RMUs are engineered to deliver long-term reliability, arc-fault protection, and ease of operation, incorporating advanced insulation and protection systems to withstand demanding environmental and operating conditions. With options for extensible or non-extensible configurations, automated or manual operation, and SCADA-ready integration, Hunter Transformers’ RMUs provide the flexibility needed to adapt to both standard and complex network requirements.
