Claims19
A composite material for use in a high-voltage device having a high-voltage electrical conductor, the composite material being adapted for covering the high-voltage electrical conductor at least partially for grading an electrical field of the high-voltage electrical conductor, the composite material comprising:
- a polymeric matrix;
- and
- at least one fiber embedded in the polymeric matrix, the at least one fiber having an average diameter of less than about 500 nm.
A high voltage device comprising:
- a high-voltage electrical conductor;
- and
- a composite material having a polymeric matrix, and at least one fiber embedded in the polymeric matrix, the at least one fiber having an average diameter of less than about 500 nm, and wherein the composite material covers the conductor at least partially for grading an electrical field of the high-voltage electrical conductor.
A method of manufacturing a high-voltage device, the method comprising:
- providing a high-voltage electrical conductor;
- winding at least one fiber around the high-voltage electrical conductor, each fiber having an average diameter of less than about 500 nm;
- and
- embedding the fibers or the fabric in a polymeric matrix, thereby obtaining a composite material which includes the fibers embedded in the polymeric matrix.
