Switchgear - Wikipedia

A switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.

Electrical substation - Wikipedia

A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.

GAS INSULATED SUBSTATIONS

Often, building new substations or increasing capacity is difficult because land is either not available or is prohibitively expensive. This conference will address regulatory, technical and business considerations for GIS. It will review GIS technology and detail current design trends and maintenance solutions for gas insulated substations.
