SF6-Protected Ring Main Unit

Product Description: 10kV SF6 Insulated Ring Main Unit (RMU)

Introducing the 10kV SF6 Insulated Ring Main Unit (RMU), a state-of-the-art solution for high-voltage electrical distribution that combines efficiency, safety, and reliability in a single package. This advanced Ring Main Unit Switchgear is designed to operate in environments with challenging conditions such as high humidity and dust, making it an ideal choice for a variety of industries and applications.

Key Features:

• Advanced SF6 Insulation: The RMU utilizes SF6 gas for insulation, ensuring that all high-voltage components are securely enclosed within a gas-tight compartment, which is crucial for safety and performance in harsh environments.
• Space-Efficient Design: With a compact design, the RMU saves valuable space in installations, making it suitable for both indoor and outdoor applications where space is at a premium.
• Ease of Operation: The user-friendly design of the RMU simplifies operational procedures, reducing the need for extensive training and minimizing the potential for errors.
• Low Maintenance: The sealed SF6 gas compartment virtually eliminates the need for regular maintenance, resulting in cost savings and increased uptime.

Technical Highlights:

• The Switchgear Cabinet is engineered for 12kV and below secondary distribution systems, excelling in high-density load areas such as commercial and industrial zones, as well as rural and township power supply networks.
• It adopts a modular design with functional units consisting of load switches, combination devices of load switches and fuses, and circuit breakers, allowing for flexible configuration and scalability.
• Each unit is equipped with an individual SF6 gas compartment, precision-welded from 3mm thick imported stainless steel, which houses the primary switching elements and busbars.
• The RMU is designed to operate safely under specified environmental conditions and is impervious to external factors due to the SF6 gas insulation.

Manufacturing Excellence:

• Japanese AMADA Laser Cutting Machine: Ensures high precision in component fabrication and adherence to delivery schedules.
• Japanese OTC Welding Robot: Guarantees the precision and airtightness of the SF6 gas compartments.
• German LEYBOLD Helium Mass Spectrometer Leak Detector: Verifies that the SF6 gas compartment's leak rate is below national standards.
• Computer-Controlled Vacuum Chamber for Pressure Equalization and Gas Filling: Ensures the gas compartment remains undistorted and maintains 99.9% purity of SF6 gas, essential for reliable insulation and arc-quenching performance.

Widespread Applications:

• The RMU is extensively used in power distribution systems of power plants and substations.
• It is also deployed in energy enterprises such as coal, oil, and chemical industries.
• The RMU finds application in transportation sectors including aviation, railways, and port facilities.
• High-rise buildings, sports venues, and construction sites are among the many other areas where the RMU is utilized.
• It is also suitable for mining enterprises and large-scale manufacturing industries.

The 10kV SF6 ring main unit switchgear stands out for its superior technical specifications, robust construction, and adaptability to diverse environments. It is a product that embodies the future of high-voltage distribution, offering a safe, reliable, and efficient solution for the modern power distribution needs.
