HEAT-RESISTANT INSULATED WIRE

A heat-resistant insulated wire that is used for a wiring or a winding in a device, has a high partial discharge starting voltage, and can achieve heat resistance and oxidation suppression of a conductor surface. The heat-resistant insulated wire (10) comprising a conductor (1), a baked film layer (...

Summary:A heat-resistant insulated wire that is used for a wiring or a winding in a device, has a high partial discharge starting voltage, and can achieve heat resistance and oxidation suppression of a conductor surface. The heat-resistant insulated wire (10) comprising a conductor (1), a baked film layer (2) provided on an outer periphery of the conductor (1), and an insulating film (3) provided on the baked film layer (2). The baked film layer (2) is a thermosetting resin layer, and the insulating film (3) is an extrusion-coated fluororesin layer. Preferably the baked film layer (2) is a urethane resin layer and has a thickness within a range of 5 to 30 μm, and preferably a diameter of the conductor (1) is within a range of 0.08 to 0.30 mm and a thickness of the insulating film (3) is within a range of 0.05 to 0.10 mm.
