Gas-insulated switchgear type series 8DN8· PDF fileThe switchgear 8DN8 for 72.5 kV corresponds to switch-gear 8DN8 for 145 kV up to 170 kV with regard to con-struction and technical design but it is significantly smaller. The extremely small component dimensions allow it to be deployed wherever space is at a premium. Continuous further development has reduced the footprint required for 145-kV GIS
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.
