HXGN-40.5kV box-type fixed AC metal-enclosed switchgear, suitable for power plants, energy storage, wind power, and photovoltaic power transformation and distribution systems. It serves as an indoor AC three-phase 40.5kV, 50Hz ring network power supply unit and high-voltage switchgear equipment for step-up substations. It can open and close the rated load current and the no-load current of the transformer, and can also open and close certain distances of overhead lines, cable lines, or capacitive currents. Circuit breakers or load switch-fuse combination electrical cabinets can open the rated short-circuit current at one time. In the power system, it is used for the protection, distribution, and control of power supply equipment, and has a complete "five-prevention" locking function. 

This switchgear complies with the national standards GB3906 "3.6kV - 40.5kV AC Metal-Enclosed Switchgear and Controlgear", GB/T11022 "Common Technical Requirements for High-Voltage Switchgear and Controlgear" as well as the national standards IEC60298 "Rated Voltage Above 1kV and Below 52kV AC Metal-Enclosed Switchgear and Controlgear" and IEC60694 "Common Clauses for High-Voltage Switchgear and Controlgear".
