The SF6 gas-insulated metal-enclosed switchgear is designed for 10kV distribution systems with a rated frequency of 50Hz. As a cabinet-type medium-voltage gas-insulated switchgear, it extends air-insulated switchgear into the GIS technology domain through its modular design, multifunctional configuration, high reliability, and compact structure. Utilizing SF6 gas as the insulating medium, integrating GIS technology with switchgear technology to form a complete product. This product is an indoor complete unit for three-phase AC single busbar and busbar sectioning, primarily used in power plants, substations, high-rise buildings, industrial and mining enterprises, and other power distribution systems to achieve control, protection, and monitoring of power supply systems and loads.
