Document Type and Number:
WIPO Patent Application WO/2021/210668
Kind Code:
A1
Abstract:
[Problem] To provide a heat-resistant insulated electric wire which is used for wiring lines or winding lines within devices, while having a high partial discharge starting voltage and enabling the achievement of heat resistance and suppression of oxidation at a conductor surface. [Solution] The above-described problem is solved by a heat-resistant insulated electric wire 10 which comprises a conductor 1, a baked coating film layer 2 that is provided on the outer periphery of the conductor 1, and an insulated coating film 3 that is provided on the baked coating film layer 2, wherein the baked coating film layer 2 is a thermosetting resin layer and the insulated coating film 3 is a fluororesin layer that is formed by extrusion for coating. It is preferable that the baked coating film layer 2 is a urethane resin layer having a thickness within the range of from 5 μm to 30 μm; it is preferable that the conductor 2 has a diameter within the range of from 0.08 mm to 0.30 mm; and it is preferable that the insulated coating film 3 has a thickness within the range of from 0.05 mm to 0.10 mm.
