Zusammenfassung:	When an insulator (1) is used in a humid atmosphere, the cooling thereof causes a humidity condensation, which is deposited on the insulator (1) surface. Drops of water formed by the humidity condensation are connected to each other that a water film substantially reducing the insulation resistance of the insulator (1) is formed. In order to solve said problem, the inventive insulator (1) is provided, at least partially, with a hydrophobe surface (6). In such a way, the water layers formed by condensation are drained off the surface or detached therefrom without connection and the drops of water produced by condensation are unable to be bound to each other, thereby making it possible to maintain a desired high insulation resistance.
