Abstract

An electrical bushing including an electrically insulating shell having a central longitudinal through hole and a first longitudinal end configured to be at a top of the bushing and a second longitudinal end configured to be at a bottom of the bushing. The bushing is configured for accommodating an electrical conductor positioned through the central longitudinal through hole of the shell. The shell includes fastening means for fastening the bushing to a wall of an electrical apparatus, through which wall the bushing is configured for allowing the electrical conductor to pass. The shell is configured for sealingly containing an electrically insulating liquid in the bushing, allowing the bushing to be liquid-filled. The shell is molded as a single piece from an electrically insulating polymeric material.
