Abstract
The invention pertains to a dielectric bushing (1′), in particular a high-voltage bushing (1′) for an electrical high-voltage apparatus. To realize the field control in the field-stressed zone (7; 7a, 7b), at least one screening electrode (6; 6a, 6b) arranged in the interior (20) of the insulator part (2; 2a, 2b; 2c) is eliminated and replaced with a non-linear electric and/or dielectric field control element (9; 9a, 9b; 9i, 9o; 9s) on the insulator part (2; 2a, 2b; 2c) in the region of the first installation flange (4; 8).
