Rotating electrical machine having high-voltage stator winding and elongated support devices supporting the winding and method for manufacturing the same

A rotating electric machine configured to operate at high-voltages comprising:

• a high-voltage magnetic circuit having,
• a magnetic core, and
• a stator winding of a high-voltage cable, said high-voltage cable having,
• a conductor configured to carry electrical current and having respective strands,
• an inner semiconducting layer arranged to surround and be in contact with said conductor,
• a solid insulation layer arranged to surround and be in contact with said inner semiconducting layer, and
• an outer semiconducting layer arranged to surround and be in contact with said solid insulation layer, said second semiconductor layer being formed from an extruded material that is configured to protect said stator winding from being damaged when drawn through said first slot, said second slot, and said third slot;
• and
• a support member positioned along and in contact with said stator winding.

A method for manufacturing a rotating electric machine configured to operate at high-voltages, comprising the steps of:

• forming a winding for a stator by positioning a cable in a first slot, a second slot, and a third slot of the stator, said cable being configured to hold a high-voltage and having
• an insulation system including
• a first semiconducting layer,
• a solid insulation layer arranged to surround and be in contact with. said first semiconducting layer, and
• a second semiconducting layer arranged to surround and be in contact with said solid insulation layer, said second semiconductor layer being formed from an extruded material that is configured to protect said stator winding from being damaged when drawn through said first slot, said second slot, and said third slot, said first semiconducting layer and said second semiconducting layer providing respective equipotential surfaces;
• and
• inserting an elongated support member axially in at least one of said first slot, said second slot, and said third slot and in contact with said cable.
