    摘要: A wrapped stator coil for use in a generator. The wrapped stator coil includes an electrical conductor bar, a laminate tape structure, and a conductive structure. The laminate tape structure is disposed about the electrical conductor bar and includes an insulative first layer adjacent the conductor bar and a conductive second layer bonded to the first layer. The conductive structure includes a first end portion, an intermediate portion and a second end portion. The first end portion is in contact with the electrical conductor bar. The intermediate portion is in contact with the conductive second layer and is not in contact with the electrical conductor bar. The insulating layer is disposed about the conductive structure and the laminate tape.

    摘要: Provided are compositions that include a dielectric matrix material (222) defining multiple voids (224) of substantially uniform respective dimension and configured as a substantially uniform array. The voids may be configured such that charges that accumulate at surfaces of at least some of the voids when the composition is immersed in a uniform external electric field interact with charges that accumulate at surfaces of at least others of the voids to cause movement of the respective charges in a direction having a component transverse to the electric field. Hollow particles (226) may be disposed within respective voids of the array of voids defined by the matrix material. Associated devices are also provided.

    摘要: Une machine de traitement de gaz comporte un circuit principal de traitement du gaz, raccordé à une chambre de compression du gaz, un compresseur de gaz, logé dans la chambre de compression, une machine électrique tournante, destinée à entraîner le compresseur de gaz, comprenant au moins une bobine pour la circulation de courant électrique en vue de la création d'un flux magnétique, et un circuit secondaire de refroidissement, convoyant du gaz depuis la chambre de compression jusqu'à la machine électrique tournante, pour le refroidissement de cette machine électrique tournante. La bobine comporte au moins un tore formé d'un enroulement de plusieurs spires (20) constituées chacune d'au moins un conducteur (22) isolé suivant sa longueur par un isolant primaire (24), l'enroulement formant le tore étant recouvert lui-même d'un isolant secondaire (26), l'isolant primaire (24) et l'isolant secondaire (26) comportant du PolyEtherEtherKetone.
