Abstract
A rectangular insulated wire includes a rectangular conductor having a generally rectangular cross section, a thermosetting resin layer provided to cover the rectangular conductor, and a plurality of thermoplastic resin layers provided on the thermosetting resin layer. An adhesion strength between the thermosetting resin layer and the thermoplastic resin layer is 50 gf/mm to 100 gf/mm.
Claims10
A rectangular insulated wire comprising:
- a rectangular conductor having a generally rectangular cross section;
- a thermosetting resin layer provided to cover the rectangular conductor,
- a first thermoplastic resin layer provided on the thermosetting resin layer;
- a second thermoplastic resin layer provided on the first thermoplastic resin layer,
- an adhesion strength between the thermosetting resin layer and the first thermoplastic resin layer being 50 gf/mm to 100 gf/mm,
- a relative crystallinity of the first thermoplastic resin layer being greater than or equal to 20% and less than or equal to 50%,
- a relative crystallinity of the second thermoplastic resin layer being higher than the relative crystallinity of the first thermoplastic resin layer by greater than or equal to 3%.
