Abstract :
The paper describes how a comprehensive range of indoor air-insulated switchgear, for ratings of 20kA to 50kA and up to 15 kV, was produced having enhanced performance, over and above that required by IEC 56, with full internal arc protection and small dimensions, incorporating many common components over the range to meet the emerging diversity of demands arising out of changes that are taking place within the market place
