ABSTRACT:
The post insulator (6) has an insulator body (8), of cured cast resin, which can be subjected to a pressure medium, and at least one potted fitting (11) penetrating the insulator body (8) and subjected to high voltage. The metallic support body (12) has a lateral surface (15). The intention is to obtain a post insulator which is of simple structure and which is designed for comparatively high mechanical loading. This is achieved by providing the lateral surface (15) of the support body (12) with a bonding layer (13) which adheres better to the lateral surface (15) than the cured cast resin. The cured cast resin is cross-linked with the bonding layer (13).
