The XGN66-12 Indoor Box-Type Fixed Metal-Clad Switchgear (hereinafter referred to as the switchgear) is a new generation of high-voltage indoor switchgear used for three-phase AC 50Hz, rated voltage 3.6kV12kV, and rated current 630A3150A distribution systems. It serves as a device for receiving and distributing electrical energy, and provides control, protection, and monitoring functions for the circuits. Its bus system includes both a single busbar system and a single busbar sectioning system. The switchgear is equipped with a reliable "five-protection" interlocking function. It can be equipped with vacuum circuit breakers such as ZN21, VS1, ZN66, ZN28, or other models, all of which provide high reliability and performance. The switchgear offers strong compatibility, an attractive appearance, a compact size (only 50% of the size of conventional switchgear), and ease of maintenance. It is widely used in power plants, substations, industrial and mining enterprises, high-rise buildings, and public facilities. It can also be combined with ring main units for use in switchgear stations. The XGN66-12 Indoor Box-Type Fixed Metal-Clad Switchgear complies with standards such as GB3906, DL/T404, GB/T11022, and IEC298.
