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.

A rectangular insulated wire comprising:
- 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 being 50 gf/mm to 100 gf/mm.
An electric generator coil formed by winding a rectangular insulated wire comprising:
- 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 being 50 gf/mm to 100 gf/mm.
A rectangular insulated wire comprising:
- a rectangular conductor having a generally rectangular cross section;
- a thermosetting resin layer provided to cover the rectangular conductor;
- and a first thermoplastic resin layer provided on the thermosetting resin layer,
- the first thermoplastic resin layer having a relative crystallinity of greater than or equal to 20% and less than or equal to 50%, the relative crystallinity being calculated based on heat of fusion and heat of crystallization measured by differential scanning calorimetry.
