Anomalous flashovers of silicone rubber insulators under the artificial rain test [PDF]
Archives of Electrical Engineering, 2021 The wet flashover voltage of medium voltage insulators made of a silicone rubber is 8% lower than the wet flashover voltage of a porcelain insulator with an identical profile. These surprising results, obtained in 2012, were confirmed again in 2019.
