Abstract
The present disclosure relates to a condenser bushing comprising a condenser core (1) and electrically conductive field-grading layers (3), which are embedded in insulating material of the condenser core (1) and arranged around a central channel for conductor (2) extending along an axis defining an axial direction, while an electric connection (6) is provided to at least one of the field-grading layers (3), wherein pairs of neighbouring field-grading layers (3) with the insulation material between them form sections of the condenser core of axial lengths L<sub>1</sub> through L<sub>n</sub> and with capacitances C<sub>1</sub> through C<sub>n</sub>, characterized in that a shape of at least one of the field-grading layers (3) deviates from cylindricality in order to reduce non-uniformity of electric field stress of the condenser bushing compared to a corresponding condenser bushing with the cylindrical field-grading layers forming sections of the axial lengths L<sub>1</sub> through L<sub>n</sub> and with capacitances C<sub>1</sub> through C<sub>n</sub>.
