Abstract (en)
[origin: CA2152029A1] The invention relates to a rotationally symmetric high voltage insulator of ceramic material, which comprises a shank having molded shields and to whose ends metal caps are shrink fitted. The ends of the insulation body in the region of the joining surfaces are here configured so as to be at least 1.05 times as thick as the shank diameter and the thickened ends are machined cylindrically and on the end faces.
