Description
Switchgear is a type of electrical equipment used to control, protect, and isolate electrical circuits and equipment. It is typically used in medium and high voltage applications, such as power generation, transmission, and distribution systems.
Switchgear can be classified into different types based on its design and application. Some common types of switchgear include:
- Air-insulated switchgear (AIS).
- Gas-insulated switchgear (GIS).
- Metal-enclosed switchgear.
- Outdoor switchgear.
Applications
- Power generation.
- Power transmission and distribution.
- Industrial facilities.
- Commercial buildings.
- Hospitals.
- Data centers.
- Mining and oil and gas.
