The XGN-24 Gas-Insulated Metal-Enclosed Ring Main Unit is a new-generation fully sealed gas-insulated switchgear manufactured using advanced welding, gas filling, and leak detection technologies. The entire design is based on a stainless-steel fully enclosed structure.
All live components are sealed inside a stainless-steel tank filled with SF6 (sulfur hexafluoride) gas, ensuring high insulation performance and operational safety. The gas tank and fuse tube achieve an IP67 protection rating, providing excellent resistance against dust and water ingress.
The equipment adopts a modular design, offering a compact structure with flexible combination and expansion capabilities. It can be configured with different functional units, including circuit breaker units and switch-fuse combination units, to meet various distribution requirements.
The product is widely used in urban power grid construction and renovation projects. It is suitable for ring main power supply and terminal distribution systems, and can also be installed in prefabricated substations and switching stations. It features a fully enclosed, maintenance-free design with compact structure and high reliability.
