  • Transformer insulation
    Patent number: 10685773
    Abstract: The present invention relates to an electrical transformer comprising an electrical insulator and a winding of an electrical conductor around a core, said insulator being formed of an essentially non-porous composite material comprising a resin matrix and up to 85% by weight of insulating fibres surrounded by the resin matrix, the composite material having a maximum moisture content of less than 0.5% by weight at 23° C. and 50% relative humidity.
    Type: Grant
    Filed: December 5, 2013
    Date of Patent: June 16, 2020
    Assignee: ABB Schweiz AG
    Inventors: Adam Michalik, Patricia Ricketts, Massimo Carmignoto, Jayram Yadava, Roberto Zannol, Miljenko Hrkac, Alessandro Mattozzi, Claire Pitois, Emmanouil Logakis, Harald Martini, Ilario Scian, Orlando Girlanda, Rudi Velthuis, Spiros Tzavalas
  • ELECTRICAL TRANSFORMER SYSTEMS AND METHODS
    Publication number: 20170301449
    Abstract: An electrical transformer includes a coil pack including windings, and spacers axially spacing turns of the windings from one another and being formed of a thermoplastic material. Sticks couple and position the spacers. The coil pack has high resistivity to creep and permits temperature rise without degradation of transformer insulation, providing for extended service life and unique methods of transformer system upgrade.
