Switchgear - Wikipedia 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.

Gas-Insulated Substations - GIS Dielectric Gas. A gas-insulated substation (GIS) uses a superior dielectric gas, SF6, at moderate pressure for phase-tophase and phase-to-ground insulation.The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in SF6 gas inside grounded metal enclosures.

Vacuum applications in the transformer production industry Air drying The Hot Air drying process is mainly used for drying of high voltage transformers windings or for drying od the active part of smaller distribution transformer. Process consists of hot air circulation followed by pumping down of the heating chamber to a pressure below < 1hPa. The design criteria of the pumping speed depends on the weight of the insulation material.
