Abstract
Official abstract text for this publication.
An insulated wire which comprises an aluminum conductor, having: an adhesion layer formed by directly baking, on the aluminum conductor, varnish containing a carboxy group; an insulation layer as an outer layer of the adhesion layer; and a reinforcement insulation layer as an outer layer of the insulation layer; and a method of producing the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. An insulated wire which comprises an aluminum conductor, having: an adhesion layer baked on the aluminum conductor; an insulation layer as an outer layer of the adhesion layer; and a reinforcement insulation layer as an outer layer of the insulation layer; wherein the adhesion layer comprises a varnish containing a carboxy group. 2. The insulated wire according to claim 1 , wherein a total thickness of the adhesion layer and the insulation layer is 20 μm or more and 85 μm or less. 3. The insulated wire according to claim 1 , wherein a resin with which the insulation layer is formed is a crystalline resin having a melting point of 180° C. or higher or an amorphous resin having a glass transition temperature of 180° C. or higher. 4. The insulated wire according to claim 1 , wherein the varnish contains polyamic acid. 5. The insulated wire according to claim 1 , wherein the reinforcement insulation layer is composed of a thermoplastic resin. 6. The insulated wire according to claim 1 , wherein purity of aluminum in the aluminum conductor is 95% or more. 7. The insulated wire according to claim 1 , wherein a resin with which the insulation layer is composed is composed of a thermosetting resin having a glass transition temperature of 180° C. or higher, and wherein a resin over 50 mass % of the resin with which the insulation layer is composed is polyamideimide or/and polyimide. 8. The insulated wire according to claim 1 , wherein a resin with which the insulation layer is composed is composed of a thermosetting resin having a glass transition temperature of 180° C. or higher, and wherein a resin over 50 mass % of the resin with which the insulation layer is composed is a mixed resin of polyamideimide and polyimide. 9. The insulated wire according to claim 1 , wherein the reinforcement insulation layer is composed of a thermoplastic resin containing at least one selected from polyether ether ketone, thermoplastic polyimide, and polyphenylene sulfide, and is formed by performing extrusion of the thermoplastic resin. 10. The insulated wire according to claim 1 , wherein a cross-sectional shape of the aluminum conductor is rectangular.
