摘要:
A high voltage ceramic and glass insulator with a function film is provided to resist pollution flashover and a preparation method is provided to produce the high voltage insulators. It is a common high voltage insulator covered with a layer of nano meter level inorganic film with the function of raising pollution flashover resisting, and the film is formed on the high voltage ceramic and glass insulator surface and made of a solution containing the titanium dioxide base, and the solution containing the titanium dioxide base includes a pure titanium dioxide solution or a binary compound oxide solution containing the titanium dioxide. The invention is suitably used for the power transmission and the transform line in the areas with the circumstance seriously polluted or in the remote mountainous areas.
