  • Electrical device having an insertable high-voltage bushing
    Patent number: 11469014
    Abstract: An insertable high-voltage bushing includes an inner conductor which extends in a longitudinal direction between a high-voltage terminal and a plug-in section of the high-voltage bushing. The plug-in section is configured for the insertion of the high-voltage bushing into a device connection part of an electrical device. An insulating body at least partially extends around the inner conductor. A housing at least partially extends around the outside of insulating body. The housing includes a tubular housing element which extends between a head fitting at the high-voltage terminal of the high-voltage bushing and a mounting flange for fastening the high-voltage bushing to a device housing of the electrical device. The housing element is made of a composite material and a secondary insulation provided between the housing element and the insulating body is formed of a dry foam.
