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.

Recycling alginate composites for thermal insulation
Carbohydrate Polymers, 2021 We present a new method for the total functional recycling of alginate-based composite materials made via ionotropic gelation. The original material, an alginate/fiberglass foam with thermal insulation characteristics, was produced following a patented process in which fiberglass waste is embedded into the polyanionic gel matrix, and the resulting ...

Dry band formation mechanism of composite insulator with generalized finite difference-time domain
电力工程技术, 2022 The pollution flashover of composite insulators is mainly the flashover caused by alternate occurrence of arc development and dry band formation. At present, researchers have investigated the development of insulator arc along the surface.
