Study on electrical properties of superhydrophobic coating covered with moss

Outdoor electrical equipment in high humidity area is easy to be polluted by parasitic organisms such as moss, which threatens the safety of power grids a lot, while resin-based superhydrophobic coating is a promising anti-pollution material for insulators. In this paper, we measured the water contact angle and the flashover voltage to study the effect of moss on superhydrophobic coatings, and found that the surface of superhydrophobic coating covered with moss turn to be superhydrophilic, and the wet flashover voltage is almost the same as the glass surface covered with moss. However, the dry flashover voltage of former is higher than the later. Therefore, the resin-based superhydrophobic give a relief to the electrical equipment covered with moss.
