What is Switchgear? | Features, Components and Classification Switchgear. For voltages below 66 kV, switchgear is generally installed indoor because of economic considerations. It is generally of metal-clad type. In this type of construction, all live parts are completely enclosed in an earthed metal casing.
Gas-Insulated Substations : GE Grid Solutions portfolio includes GIS solutions from 60 to 800 kV, along with hybrid, mobile and digital GIS solutions, Gas-Insulated lines and other secondary products to maximize switchgear and network operation, including spring-operated mechanisms for AIS, GIS and generator circuit breakers.
GIS | High-Voltage Gas Insulated Switchgear Substations Insulated Substations . A gas insulated substation (GIS) is a high voltage substation in which the major structures are contained in a sealed environment with sulfur hexafluoride gas as the insulating medium. GIS technology originated in Japan, where there was a substantial need to develop technology to make substations as compact as possible.

Switchgear - Wikipedia for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher.
