RM6-C 12kV SF6 Gas-Insulated Ring Main Unit (RMU) – Compact Fully-Enclosed Metal-Clad Switchgear for Medium Voltage Distribution

RM6-C SF6 Gas-Insulated Ring Main Unit (12kV/24kV RMU)

Product Overview

The RM6-C series is a high-performance, fully insulated, and hermetically sealed ring main unit (RMU) designed for 12kV and 24kV medium voltage power distribution. All primary high-voltage components, including the busbars and switch-disconnectors, are housed in a robust, maintenance-free stainless steel tank filled with SF6 gas. This compact, modular switchgear is the ideal solution for urban grids, industrial power centers, and compact substations where space is limited and environmental reliability is paramount.

Core Features & Technical Advantages

• Fully Hermetically Sealed: The gas-filled stainless steel tank protects all live parts from external influences like humidity, dust, and coastal salt spray.

• Integrated Intelligent Monitoring: Features independent secondary instrument compartments equipped with digital meters and microcomputer protection terminals for real-time tracking.

• Precision Gas Monitoring: A front-mounted SF6 gas pressure gauge provides immediate visual confirmation of the insulation medium’s status.

• Advanced Safety Interlocking: Incorporates a clear circuit mimic diagram and sophisticated mechanical interlocks to prevent incorrect operations.

• Compact “Common Tank” Design: The ultra-compact footprint allows for installation in narrow basements and small prefabricated outdoor stations.

• Personnel Protection: Includes an internal arc-proof design and red “DANGER” high-voltage warning labels on the cable compartment doors.
