Abstract | The aim of this paper is to present a review of the development and application of superhydrophobic insulation for outdoor high voltage applications. The methods of preparing insulation exhibiting superhydrophobic properties in order to mitigate the pollution problem under high voltages in the outdoors are explored. In addition, existing evaluation techniques at the material development stage are reviewed and potential new modifications are discussed. The self-cleaning and anti-icing properties, the electrical performance and prospects of superhydrophobic insulators are also addressed. Although superhydrophobic insulators may show promising behavior in small-scale laboratory conditions that do not employ electrical stress, the effect of surface micro-nano structure responsible for the superhydrophobicity on performance under the actual outdoor and weathering conditions under voltage remains to be fully understood and verified. Therefore, there is a need to verify the feasibility of superhydrophobic insulators for outdoor high voltage applications with a solid evaluation protocol, while employing material screening methods in the laboratory, and with reference to field experience. |
