More Information
Summary: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; 7 a , 7 b), at least one screening electrode ( 6; 6 a , 6 b) arranged in the interior ( 20 ) of the insulator part ( 2; 2 a , 2 b ; 2 c) is eliminated and replaced with a non-linear electric and/or dielectric field control element ( 9; 9 a , 9 b ; 9 i , 9 o ; 9 s) on the insulator part ( 2; 2 a , 2 b ; 2 c) in the region of the first installation flange ( 4; 8 ).
