  • Insulating cover for a bar to bar connection of a stator winding of an electric machine
    Patent number: 7965013
    Abstract: An insulating cover or a bar-to-bar connection of a stator winding of an electric machine has only one opening and is made from a flexible insulating material embedding the bar-to-bar connection entirely in a tight fit. Methods for producing and applying such an insulating cover are also provided.
    Type: Grant

  • Superconducting conductor having multiple transposed strands with internal cooling channels, and method of manufacture
    Patent number: 5073679
    Abstract: A superconducting conductor comprises a first fraction of prior-tinned strands (1, 3, 5, 7, 9, etc. . . . ) and an additional fraction of non-prior-tinned strands (2, 4, 6, 8, 10, etc., . . . ). The strands of the first fraction and of the additional fraction alternate regularly and are maintained in a coherent assembly after being assembled with transposition by heating to melt the layer of tin on the prior-tinned strands, with the tin from said layer then solidifying, thus providing substantially point adherence between the previously tinned strands while leaving channels (11, 12, etc. . . . ) inside the superconducitng conductor for cooling liquid circulation. The invention is also to a method of manufacturing such a superconducting conductor.
