Abstract

The icing flashover is increasingly becoming a serious problem with the development of the extra-high voltage engineering. Reducing the bonding strength between the substrate and the ice by super-hydrophobic coating is a choice for the anti-icing. The bare insulator, RTV coated insulator and the super-hydrophobic insulator are chosen for comparing. The experimental facility is set up. The vertical bonding strength, the vertical fracture energy, the shear bonding strength and the shear fracture energy are detected after first ice glaciations and second one. Results show that bonding strength between the super-hydrophobic substrate and the ice is less than that of the RTV coated insulator and the ice. The deiced surface still shows good super-hydrophobicity and the small ice bonding strength keeps almost the same which show good prospect for the anti-icing and de-icing.
