Abstract:
An electrical conductor winding comprising a plurality of laminates of electrical insulation, each laminate of electrical insulation having a first surface and a second surface, the first surface of each laminate of electrical insulation being flat and the second surface of each electrical insulation having a slot, at least one aperture extending through each laminate of electrical insulation from the slot to the first surface, each laminate of electrical insulation having an electrical conductor arranged in the slot, each aperture having an electrical connector to connect the electrical conductor in the slot in one laminate of electrical insulation with the electrical conductor in the slot in an adjacent laminate of electrical insulation, the laminates of electrical insulation being arranged such that the first surface of one laminate of electrical insulation abuts and is bonded to the second surface of an adjacent laminate of electrical insulation and the laminates of electrical insulation comprises a glass-ceramic material, the glass-ceramic material comprises at least one phase whose combined thermal expansion substantially matches the thermal expansion of the electrical conductor.
