  • Spark-over prevention device for high-voltage bushing
    Patent number: 8759683
    Abstract: A high-voltage bushing includes a housing and a tube disposed within the housing. A conductor is disposed within the tube. An electrically conductive contact member is connected to the tube and has a first opening to receive and contact the conductor. Accordingly, spark-over between the inner surface of the tube and the outer surface of the draw-lead cable caused by a high-frequency transient is substantially prevented.
