Medium Voltage Switchgear

Medium-voltage switchgear refers to complete power distribution systems operating at AC voltage levels of 1 kV to 35 kV, consisting of switching devices, protection/control/measurement components, enclosures, and internal connections. It serves as a critical link in power systems, connecting the high-voltage side of transformers to the power grid. The core standard is IEC 62271. It is primarily used for the reception, distribution, control, protection, and monitoring of electrical energy on the medium-voltage side of power systems, serving as the core equipment for substations, distribution rooms, and industrial/municipal power supply systems.
