US Patent 8003891 High-voltage outdoor bushing

An exemplary high-voltage outdoor bushing is disclosed which includes a conductor extended along an axis, a condenser core and an electrically insulating polymeric weather protection housing molded on the condenser core. The condenser core can contain an electrically insulating tape which is wound in spiral form around the conductor. Capacitance grading insertions can be arranged between successive windings of the tape. A cured polymeric insulating matrix embeds the wound tape and the capacitive grading insertions. A moisture diffusion barrier can be incorporated inside the condenser core prior to molding the weather protection housing.
