4 ABB Group | Slide 12ZX TechnologyImproved availability of GIS concept over AIS conceptAIS concept Insulation of medium voltage by Air Ambient conditions have influence on insulation(humidity, dust, altitude ..) Dimensions and ageing behavior depend on quality ggpq yof insulation during lifetime of switchgearGIS concept medium voltage parts are inside of sealed tankAir is replaced by non-reactive insulating gas. Ambient conditions do not have influence on insulation Dimensions and ageing behaviour are determined through the design and remain constant during lifetime of the switchgear SF6 ABB Group | Slide 13SF6ZX TechnologyOur offering Highest safety for employees In GIS all live parts are installed completely touch proof.

5 Due to SF6 filled IP65 design of MV gcompartments the probability of internal faults is smaller than in any other Switchgear designother Switchgear design. Even in the unlikely case of an internal arc personnel is completelyinternal arc personnel is completely safe as the resulting pressure is guided and reduced via an optional dt t (ZX2tdd)duct system.
