High-voltage bushing with conductive inserts for dc voltage and method for producing the bushing

Abstract

A high-voltage bushing with conductive inserts for a DC voltage has a bushing body surrounding a high-voltage conductor and containing a paper insulation. The bushing body tapers conically, at least at one end region thereof, from a ground-potential-side location to a high-voltage-side end and is surrounded by an insulating barrier. In order to provide a high-voltage bushing of this type with a particularly good potential distribution, the outside of the bushing body is coated at least in the region of the at least one end region with a coating to form a coating layer, which has a greater electrical conductivity than the bushing body.
