  • Eco-efficient alternatives to SF6: Continuing the AirPlus

    May 30, 2019When designing gas-insulated switchgear (GIS) with SF 6 alternatives, one important task is to compensate the lower insulation performance – to ensure no flashovers occur during operation and dielectric tests. But SF 6 can also serve as switching medium, today frequently applied in ring main units (RMUs). Up to now facing the ‘switching challenge’ has been circumvented by using vacuum
