XHSRM6-12 Gas-Insulated Metal-Enclosed Switchgear

Technical parameters

good Environmental Adaptability
One of the great majority significant advantages of Gas-Insulated Metal-Enclosed Switchgear is its ability to operate efficiently under special environmental conditions. The switchgear’s live components are completely sealed within a 0.04Mpa SF6 gas compartment, preventing exposure to external contaminants such as dust, humidity, and corrosive gases. This design makes it suitable for applications in high-altitude areas, coastal regions with high salt fog, desert regions with strong wind and sand, and heavily polluted industrial zones. Unlike traditional air-insulated switchgear, GIS remains unaffected by external climate variations, ensuring stable and long-term operation.

Compact Design with Flexible Expansion
Gas-Insulated Metal-Enclosed Switchgear is designed with a modular structure, allowing for flexible combinations of functional units. Each module is housed in a gas-sealed compartment, and busbars can be extended in both left and right directions through bus connectors. This design enables easy expansion and adaptation to different power distribution needs. Additionally, the compact structure significantly reduces installation space, making GIS ideal for urban power distribution, small substations, and industrial applications where space is limited.

High-Performance Engineering and Design
Advanced engineering techniques are employed in the design and manufacturing of Gas-Insulated Metal-Enclosed Switchgear to ensure optimal performance. The application of computer-aided three-dimensional simulation, including electric field analysis, magnetic field analysis, and mechanical movement simulation, guarantees precise technical parameters. These design strategies enhance the switchgear’s operational reliability and efficiency, reducing the risk of electric faults and performance degradation over time.

special Sealing and Welding Technology
The gas competitions of Gas-Insulated Metal-Enclosed Switchgear are constructed using high-precision laser-cut stainless steel plates and welded by ABB robotic systems. This ensures good accuracy in material dimensions and welding quality. Furthermore, advanced vacuum extraction and nitrogen leak detection techniques are used to maintain airtight sealing, achieving an impressively low SF6 gas leak rate of 0.01% per year.

Enhanced Cleanliness and Quality Control
To maintain high insulation reliability, Gas-Insulated Metal-Enclosed Switchgear undergoes a rigorous cleaning process. The gas compartment components are cleaned using ultrasonic technology, and assembly is conducted in a controlled cleanroom environment. This meticulous process ensures that SF6 gas moisture levels remain below 150ppc, exceeding national standards and enhancing insulation stability. These measures significantly reduce the possibility of internal faults and improve overall system durability.

Intelligent Monitoring and Protection
Modern Gas-Insulated Metal-Enclosed Switchgear incorporates smart monitoring and automation features. By integrating with communication networks and power automation systems, GIS enables remote control, remote measurement, and remote signaling (often referred to as “three-remote” functions).

Specialized Cable Branching Solutions
With the increasing demand for distributed ring network switching stations, Gas-Insulated Metal-Enclosed Switchgear is specifically designed to support various cable branching applications. The busbar system enables left and right cable branching through bushings, making it highly suitable for configurations involving one or multiple load break switches. This feature provides users with a flexible and cost-effective power distribution solution, reducing installation complexity and improving network reliability.

Gas-Insulated Metal-Enclosed Switchgear stands out as a reliable, compact, and low-maintenance power distribution solution. Its fully sealed design ensures strong environmental adaptability, while its modular structure provides flexible expansion options.
