SF6 Insulated Ring Main Unit (RMU)

Product Description: 10kV SF6 Ring Main Unit Switchgear

The 10kV SF6 Gas-Insulated Ring Main Unit is a cutting-edge solution for high-voltage power distribution systems. This compact and highly secure unit encapsulates all high-voltage live parts within a sealed SF6 gas chamber, offering a range of benefits including reduced size, enhanced safety, ease of operation, and maintenance-free operation. It is widely utilized across various sectors such as real estate, industrial and mining enterprises, and urban network upgrades, particularly suited for high-humidity and high-dust environments where traditional high-voltage distribution systems may falter.

Key Features and Advantages:

• Compact Design: The RMU's compact form factor saves space and is ideal for installations where footprint is a concern.
• High Safety Standards: The SF6 gas insulation ensures that the high-voltage components are safely contained, reducing the risk of accidents and electrical hazards.
• Simplicity in Operation: The design allows for straightforward operation, reducing the need for complex procedures and training.
• Maintenance-Free: The sealed SF6 gas chamber eliminates the need for routine maintenance, lowering operational costs and downtime.

Technical Specifications and Requirements:

The Inflatable Ring Main Unit is designed for applications in 12kV and below secondary distribution systems, making it particularly suitable for 12kV power supply lines, ring network supply, dual-radiation supply, and cable feeder networks in commercial and industrial areas with high power demands and density. SF6 Gas-Insulated RMUs represent a new generation of miniaturized, modular switchgear, composed of main switches such as load switches, load switches with fuse combinations, and circuit breakers, which can be combined and expanded in any configuration. Each unit cabinet is equipped with an independent SF6 gas chamber, crafted from 3mm imported stainless steel plates welded using laser technology, housing the primary switch elements and busbars within. The switchgear's design and craftsmanship ensure safe operation under given environmental conditions and in special environments. The use of SF6 gas insulation means that all high-voltage live parts are sealed within the SF6 gas chamber, making the equipment impervious to environmental influences.

Manufacturing Equipment:

• Amada Laser Cutting Machine: Ensures precision in the machining of RMU components and timely delivery.
• OTC Welding Robot: Guarantees the welding accuracy and gas-tightness of the SF6 gas chambers.
• LEYBOLD Helium Mass Spectrometer Leak Detector: Ensures the SF6 gas chamber's leak rate is below national standards.
• Computer-Controlled Vacuum Chamber: Ensures the gas chamber does not deform and maintains 99.9% purity of SF6 gas, ensuring reliable insulation and arc-quenching performance of the RMU.

Application Fields:

• Power generation plants and substations
• Coal, oil, and chemical energy enterprises
• Aviation, railway, and port transportation enterprises
• High-rise buildings and sports facilities
• Construction, mining enterprises, and large-scale manufacturing industries

The 10kV SF6 Gas-Insulated RMU is a testament to the commitment to safety, reliability, and innovation in high-voltage power distribution. With its advanced features and robust construction, it stands as a preferred choice for a wide range of industrial and commercial applications.
