The growing importance of gas-insulated switchgear· Users: Users are utilities and industries that use HV equipment. Gas Insulated Switchgear . Photo: ABB. Gas insulated switchgear (GIS) is very compact form of switchgear. Because of the use of SF6 (sodium hexafluoride) insulation, the size of the switchgear reduces drastically. This product is normally used in medium and high voltage application.
Gas-insulated switchgear up to 245 kV, 50 kA, 4000 A Type 8DN9· PDF fileThe pressurized gas inside the enclosure in combination with the film insulation provides insulation against high voltage. The high-voltage connection to the switchgear is established via the primary conductor, which is supported by a gastight bushing. The secondary connections are routed via a gastight bushing plate to the terminal box.
Gas-insulated Switchgear Manufacturer in China -KDM Gas Insulated Switchgear is a class of switchgear, which uses a special gas, superior dielectric gas (SF6), as the main insulation material. The SF6 insulates circuit breaker interrupters, switches, high voltage conductors, current transformers and voltage transformers.
