1. Innovative Insulation & Maintenance-Free Design
Hermetic Sealing: All high-voltage live components are fully enclosed within a 3mm 304 stainless steel gas tank, shielding the switchgear from external elements like humidity, dust, and corrosive gases. This ensures continuous, reliable operation without the need for maintenance throughout its lifespan.
Eco-Friendly Insulation: Using nitrogen or dry air instead of traditional SF6 gas eliminates environmental risks associated with greenhouse gas emissions and leakage, making it a sustainable choice for modern power grids.
2. Premium Manufacturing & Quality Assurance
German-Engineered Precision: The gas tank is fabricated using state-of-the-art laser cutting and welding equipment from TRUMPF, Germany, ensuring superior airtightness and aesthetic appeal.
Stringent Leak Detection: Equipped with SEILER’s fully automated helium leak detection and gas filling systems, the RMU achieves an ultra-low leakage rate of ≤0.01% per year. The gas purity within the tank reaches 99.99%, extending the product’s service life to an impressive 40 years.
3. Flexible Modular Configuration
Customizable Design: Its modular architecture allows seamless assembly of single-gas-tank units or shared-tank configurations, adapting effortlessly to diverse power distribution requirements, from simple radial networks to complex grid setups.
4. Enhanced Safety & Intelligent Monitoring
Dual Interlock System: Integrated mechanical and electrical interlocks prevent malfunctions caused by incorrect operations, safeguarding both equipment and personnel.
Smart Automation: Advanced temperature-rise and density monitoring devices, combined with current-voltage monitoring systems, enable unattended substation operation and support “Five Remote Functions” (remote control, signaling, measurement, regulation, and fault recording).
