Abstract
A high voltage seismic bushing charged with an insulating material has a porcelain tube having an adapter rigidly connected to one end of the tube. A connecting plate is rigidly connected to a mounting flange. The adapter is flexibly connected to the connecting plate such that the porcelain tube is free to move relative to the mounting flange in the event of an earthquake. The means for flexibly connecting the adapter to the connecting plate utilizes a damping mechanism to attenuate the movement of the porcelain tube. A resilient buffer member is interposed between the adapter and the connecting plate to provide a predetermined spacing therebetween and absorb the impact due to the movement of the adapter relative to the connecting plate. A sealing member seals the interface between the adapter and the connecting plate for containing the insulating material charged therein.
