Abstract
There is disclosed a multilayer insulated wire comprising a conductor and solderable extrusion-insulating layers made up of two or more layers for covering the conductor, wherein at least one insulating layer is formed by a resin mixture comprising 100 parts by weight of a resin (A), of at least one selected from polyetherimide resins and polyethersulfone resins, and 10 parts by weight or more of a resin (B), of at least one selected from polycarbonate resins, polyarylate resins, polyester resins, and polyamide resins. There is also disclosed a transformer using the multilayer insulated wire. The multilayer insulated wire is excellent in heat resistance, solderability, and coilability, and is favorably suitable for industrial production. The transformer is excellent in electrical properties and high in reliability.
