Abstract
The present disclosure relates to a bushing including an electrical conductor comprising a terminal at a first end of the bushing. The bushing also includes an electrically insulating condenser core arranged around the conductor and defining a central longitudinal through-hole through which the conductor extends. The bushing also includes a plurality of concentric field-grading layers arranged in the condenser core, comprising an inner field-grading layer and an outer field-grading layer. The bushing also includes an electrically conductive head electrically connected with the conductor passing there through, forming a gas-tight cap of the first end of the bushing outside of the condenser core, sealingly engaging a circumferential lateral outer surface of the condenser core and sealingly engaging the conductor. The bushing also includes an electrically conductive connection between the inner field-grading layer and the head.
