High-voltage switchgear is the common name for metal-enclosed switchgear. It is a complete distribution device that assembles relevant electrical equipment within an enclosed metal casing according to a specific circuit configuration.

High-voltage switchgear is extensively used in power distribution systems for receiving and distributing electrical energy. It enables the connection or disconnection of specific power equipment or lines based on grid operational requirements.

Furthermore, it facilitates the rapid isolation of faulty sections from the grid during equipment or line failures. This ensures the continued normal operation of unaffected grid components while safeguarding both equipment and the safety of operational and maintenance personnel. Consequently, high-voltage switchgear constitutes critically important distribution equipment, whose safe and reliable operation holds profound significance for the entire power system.
