1-3. (canceled)
A wire resistant to degradation caused by partial discharges, comprising:
- a core formed of an electrically conductive material;
- and
- an insulator surrounding the core, wherein the insulator comprises:
- a first insulating layer immediately adjacent the core and formed of an organic polyether imide, wherein the first insulating layer has a thickness that is between approximately 30% and approximately 45% of a total thickness of the insulator;
- and
- a second insulating layer that surrounds the first insulating layer and that is formed of an organic polyamide imide, wherein the second insulating layer has a thickness that is between approximately 70% and approximately 55% of the total thickness of the insulator.
