  • Dry-type high-voltage winding
    Patent number: 6445269
    Abstract: The invention concerns an air-core primary voltage winding comprising a conductive wire coil coated with an insulating sheath, characterized in that said coil (1) is encapsulated in a high voltage insulating thermoplastic resin (2), and in that it further comprises an electroconductive potential fixing surface layer (3) in thermoplastic resin compatible with the thermoplastic resin of the insulating encapsulation (2), deposited on this encapsulation.

  • Method for compacting electrical windings equipping transformers
    Patent number: 5463806
    Abstract: At least one electrically conducting wire is coated with an electrically insulating material and wound in non-tightly coiled turns in a uniform direction of rotation. A direct electrical current is passed in the turns of the winding, preferably by repetitive sequences interspersed with stop periods, so as to create therein electromagnetic forces of mutual attraction between the turns, tending to bring them closer together in pairs and thus to reduce the height of the winding.
