INSULATING CAP FOR AN END WINDING OF AN ELECTRICAL MACHINE WORKING AT HIGH VOLTAGE AND MACHINE HAVING SUCH AN INSULATING CAP

摘要

The insulating cap (16a) has a cap main structure having an inner space (17) that is provided with a U-shaped profile. An opening (23) is provided with one side of cap main structure that is provided with a cover semiconductor layer (21) that is provided on outer side of an insulating layer (20). The electrical connection units are provided at inner side of insulating layer. A gradient layer (19) is embedded in inner side of insulating layer. The external surface of cap main structure is ground. An independent claim is included for high-voltage electrical machine.
