Switchgear is an electrical equipment used in medium and high voltage applications like power generation, transmission, and distribution systems to control, protect, and isolate electrical circuits and equipment.

Switchgear can be classified into different types based on its design and application. Some common types of switchgear include:

  • Air-insulated switchgear (AIS): Air-insulated switchgear (AIS) is an electrical switchgear that uses air as a medium for insulation and circuit interruption.
  • Gas-insulated switchgear (GIS): Gas-insulated switchgear (GIS) is an electrical switchgear that uses gas as an insulating medium to isolate and interrupt electrical circuits.
  • Metal-enclosed switchgear: Metal-enclosed switchgear is an electrical switchgear that securely encloses and safeguards electrical components and connections within a sturdy metal enclosure.
  • Outdoor switchgear: Outdoor switchgear is electrical equipment designed for outdoor environments like substations and utility yards, ensuring efficient and safe operation.
