RMU Series
12kV Ring Main Unit
Why choose ZY POWER for this project
Compact MV distribution layout
RMU is suitable for secondary distribution rooms, compact substations and utility distribution nodes where panel footprint is limited.
Loop-feed network configuration
Incoming and outgoing ring network modules can be arranged with transformer protection or metering modules according to the single-line diagram.
Transformer protection options
Fuse-switch or vacuum breaker protection can be reviewed according to transformer capacity, fault level and project specification.
Automation-ready by project
Motor operation, auxiliary contacts, RTU interface, CT/PT and communication options can be added when distribution automation is required.

Request evidence packageRMU ring main unit is a compact medium-voltage switchgear solution for 12 kV secondary distribution, loop-feed networks, compact substations and transformer protection. Compared with a full metal-clad switchgear lineup, an RMU is usually selected when the project needs a smaller footprint, simpler feeder arrangement and fast installation. Buyers should confirm module combination, load break switch or vacuum breaker function, fuse protection, automation requirement, cable direction, enclosure condition and routine test scope before production.
What Buyers Should Confirm
- Rated voltage, rated current, short-circuit level and system earthing method.
- Module quantity and function: incoming, outgoing, transformer protection, metering or busbar section.
- Load-break switch, fuse-switch or vacuum breaker requirement and relay or automation scope.
- Cable entry direction, enclosure environment, routine test report and packing requirement.
