Detailed Product Description
Air-Insulated Ring Main Unit (RMU) – Future-Proof Medium Voltage Solution
Core Advantages
- Sustainable Innovation
▶ 100% SF6-free design eliminates greenhouse gas risks and disposal costs.
▶ 60% lower carbon footprint vs. conventional RMUs (verified by EPD certification).
- Military-Grade Protection
▶ Hermetically sealed stainless-steel enclosures withstand 100kA short-circuit currents.
▶ Triple interlocking mechanism (IEC 62271-200) prevents human error.
- Space-Saving Architecture
▶ 350mm width – 40% smaller footprint than SF6-based alternatives.
▶ Modular design supports flexible configurations (load break switches + fuses/breakers).
- Digital Intelligence
▶ Optional smart sensors for real-time monitoring (temperature, partial discharge, mechanical status).
▶ Seamless integration with energy management platforms via Modbus RTU, IEC 61850, or DNP3 protocols.
