Modular condenser bushing

摘要

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.
