The XGN66-12 is a box-type fixed metal-enclosed switchgear designed for 3.6kV to 12kV three-phase AC 50Hz systems. It serves as a critical device for receiving and distributing electrical energy in power plants, substations, and industrial facilities. Featuring a compact air-insulated design (only about 50% the volume of conventional switchgear), reliable “Five-Prevention” mechanical interlocks, and compatibility with VS1/ZN63 vacuum circuit breakers, it ensures safe, space-saving, and maintenance-friendly operation.
The XGN66-12 series is a new generation of indoor high-voltage switchgear suitable for single-busbar or single-busbar-sectionalized systems. It is widely used in power plants, substations, industrial and mining enterprises, and high-rise buildings for power distribution, circuit control, protection, and monitoring. The switchgear can also be combined with ring main units in switching stations, making it a versatile solution for urban and rural grid upgrades.
1.Compact Air-Insulated Design: The cabinet utilizes air insulation with no need for SF6 gas. Its volume is significantly reduced to approximately 50% of conventional switchgear, saving valuable floor space in electrical rooms.
2.Reliable “Five-Prevention” Interlocks: Equipped with a mandatory mechanical interlocking system between the main switch, disconnector, earthing switch, and cabinet door. This ensures reliable protection against misoperation, meeting the “Five-Prevention” safety requirements.
3.Flexible Configuration: The switchgear can be equipped with various vacuum circuit breakers and rotary disconnectors. It features a pressure relief channel to ensure personnel safety during internal arc faults.
4.Clear Observation & Maintenance: Observation windows on the doors allow operators to monitor the internal working status of components without opening the cabinet, facilitating safe inspection and maintenance.
