Abstract: The present invention is a condenser-type electrical bushing having a mounting flange, an upper weather casing connected to the mounting flange, a central electrode and a lower casing, both supported by the upper weather casing. A condenser is wound about the central electrode. The bushing further has a plurality of wedging blocks which are rigidly connected to the condenser and located above the mounting flange such that upon mechanical failure of the upper weather casing the central electrode and the condenser are prevented from falling into the electrical apparatus.

Abstract: Electrical bushing having a plurality of individual condenser modules coaxially enclosing an electrical conductor. The condenser modules are spaced apart to define a gap therebetween. Each condenser module includes a plurality of concentric, axially extending, electrically conductive layers. The axial spacing between the ends of corresponding conductive layers in adjacent, coaxial condenser modules is varied across the condenser modules in order to control the voltage gradient across the gap between the condenser modules and to provide uniform capacitance across the bushing.

Abstract: An electrical insulating bushing with longitudinally extending channels for parallel coolant flow across the entire inner and outer surfaces of a hollow conductor. A first channel is formed by a plurality of ducts disposed between the conductor and a layer of insulative material which surrounds the electrical conductor; while a second channel is formed by a tubular member concentrically disposed within and radially spaced from the electrical conductor. An insulative bushing housing is spaced from the outer surface of the layer of insulative material to form a longitudinally extending third channel, the ends of which are in fluid flow communication with the ends of the first channel.
