Abstract
An insulator with a molding made of ceramic and a hydrophobic coating applied to the surface of the molding is disclosed, the hydrophobic coating comprising a plasma polymer having been applied directly to the ceramic. The previously customary glaze on the surface of the ceramic is replaced by the plasma polymer. Such an insulator has high long-term stability with regard to its electrical insulating capability. It is possible to dispense with complicated shaping of the molding to increase the leakage path over the surface of the ceramic and with the application of a glaze, which means a considerable cost saving.
