Abstract
A duct for connecting an electrical device insulated with gas with a terminal location located in atmospheric air, the duct has a gas filled bushing insulator, at least one tubular field control electrode located inside the bushing insulator, at least one insulating tube having an end facing a potential-guiding region of the duct, the at least one field control electrode being formed by a conducting portion on the end of the at least one insulating tube, a bushing conductor around which the at least one insulating tube is arranged coaxially, the insulating tube having a ground potential-side end, and a holder which holds the insulating tube at the ground potential-side end outside a region loaded with high field intensity.
