DFW-12 High-Voltage Cable Branch Box
RMU Ring Main Unit

DFW-12 High-Voltage Cable Branch Box

The High-Voltage Cable Branch Box (Ring Main Unit) integrates 12/24kV switchgear, circuit breakers, load switches, current and voltage transformers, 12/24kV power PT, ring main unit FTU, RTU, communication control terminal (CCU), 12/24kV metering and automatic meter reading, UPS power supply, and indicator instruments into a movable, sealed, and moisture-proof stainless steel enclosure. This design achieves the integration of primary and secondary systems in urban power distribution networks, modularizes assembly, shortens the construction cycle, and significantly improves the reliability of urban power grid operation.
