Summary:abababcabiosabcThe invention pertains to a dielectric bushing (′), in particular a high-voltage bushing (′) for an electrical high-voltage apparatus. To realize the field control in the field-stressed zone, at least one screening electrode arranged in the interior of the insulator part is eliminated and replaced with a non-linear electric and/or dielectric field control element on the insulator part in the region of the first installation flange.
