Superhydrophobic coatings for electrical insulators
MetadataShow full item record
Dielectric breakdown in electrical insulators is a frequently encountered phenomenon leading to surface damage, material loss and eventually a complete breakdown of electrical insulators. Dielectric breakdown is accelerated under severe conditions such as humidity and rain. As a result, the service life of the electrical insulators is affected. In our work, we employed superhydrophobic coatings, which are extremely repellent towards water, in an attempt to retain the dielectric strength of electric insulators in the presence of water. In addition, we studied the influence of surface roughness ...
