SF6 Gas-insulated RMU Ring Main Unit 12kV

Description

The SF6 Gas‑Insulated RMU (Ring Main Unit) is compact, high‑performance medium‑voltage switchgear for power distribution networks. It uses SF6 gas as insulation and arc‑extinguishing medium, integrating load switches, earthing switches and busbars in a sealed enclosure. Widely used in urban power grids, industrial parks, commercial complexes and renewable energy projects, it ensures efficient and safe power control, protection and distribution.

Key Features

• Superior SF6 Performance: High dielectric strength and arc‑extinguishing capacity ensure stable operation for 12kV‑24kV systems, preventing leakage, short circuits and flashovers.
• Compact Space‑Saving Design: Sealed integrated structure fits indoor substations and space‑limited urban sites, optimizing on‑site layout.
• High Safety & Reliability: Complete mechanical & electrical interlocks prevent misoperation; built‑in SF6 leakage monitoring complies with global safety standards.
• Low Maintenance & Long Service Life: Hermetic housing resists dust, moisture and corrosion; maintenance‑free operation with service life up to 20 years.
• Flexible Adaptability: Supports ring‑network and radial wiring, compatible with transformers and cables for diverse grid topologies.
• Eco‑friendly & Cost‑effective: Recyclable SF6 gas reduces waste; high efficiency cuts energy loss and replacement costs.
