Control cabinets are assembled with switchgear, measuring instruments, protective devices, and auxiliary equipment according to electrical wiring requirements, either in a sealed or semi-sealed metal cabinet or on a panel. Their layout should meet the operational requirements of the power system, facilitate maintenance, and not compromise the safety of personnel or surrounding equipment.

During normal operation, circuits can be connected or disconnected using manual or automatic switches. In case of faults or abnormal operation, protective devices are used to cut off the circuit or trigger an alarm. Measurement instruments can display various parameters during operation and can also adjust certain electrical parameters, providing alerts or signals for deviations from normal operating conditions. Commonly used in various power generation, distribution, and transformation stations.

Control cabinets come in many varieties, including electrical control cabinets, variable-frequency control cabinets, low-voltage control cabinets, high-voltage control cabinets, pump control cabinets, power supply control cabinets, explosion-proof control cabinets, elevator control cabinets, PLC control cabinets, fire control cabinets, brick-making machine control cabinets, and more.
