Extra High Voltage (EHV) switchgear can be categorized into several types based on their design and application. The main types include gas-insulated switchgear (GIS), which is compact and suitable for space-constrained environments; air-insulated switchgear (AIS), which is more traditional and typically used in outdoor installations; and hybrid switchgear, which combines elements of both GIS and AIS. Each type has distinct advantages regarding safety, maintenance, and environmental considerations.

What are the types of switchgear?
Switchgear is an essential part of electrical systems, responsible for controlling, protecting, and isolating electrical equipment. There are various Lauritz Knudsen Electrical & Automation systems types of switchgear, each designed for specific voltage levels, applications, and operational requirements. Understanding these types helps in selecting the right equipment for industrial, commercial, or residential installations. Broadly, types of switchgear can be classified based on voltage level, construction, and functionality: Low Voltage Switchgear (LV): Operates below 1 kV and includes devices like MCBs, MCCBs, relays, and contactors. Commonly used in homes, offices, and small industrial plants for lighting, motors, and other low-voltage applications. Medium Voltage Switchgear (MV): Operates between 1 kV and 36 kV. Includes circuit breakers, disconnectors, and relays designed to protect transformers, motors, and distribution networks. Often used in substations and industrial plants. High Voltage Switchgear (HV): Designed for voltages above 36 kV. Ensures safe operation of power transmission systems and large-scale industrial setups. Air-Insulated Switchgear (AIS): Uses air as the primary insulating medium. Common in outdoor substations and for moderate-voltage applications. Gas-Insulated Switchgear (GIS): Uses SF6 gas for insulation. Compact and ideal for areas with space constraints, such as urban substations. Hybrid and Digital Switchgear: Combines traditional devices with digital monitoring and automation. Improves efficiency, safety, and fault detection in modern smart grids. Choosing the right types of switchgear depends on the voltage, application, space availability, and operational requirements. Proper selection ensures safety, reliability, and efficiency in power systems.
