INSULATED WIRE

摘要

PROBLEM TO BE SOLVED: To provide an insulated wire including an insulating coat having mechanical property and heat resistance equal to or greater than the insulating coat of a conventional insulated wire, and improved partial discharge starting voltage by actualizing a lower dielectric constant.SOLUTION: The insulated wire includes the insulating coat formed of a polymer alloy including an amorphous thermosetting resin and an amorphous thermoplastic resin. The insulating coat has a sea-island structure, where the amorphous thermosetting resin forms a sea component of the sea-island structure and the amorphous thermoplastic resin forms an island component of the sea-island structure.
