MULTI-LAYER INSULATED ELECTRICAL WIRING AND ELECTRICAL/ELECTRONIC DEVICE USING SAME

摘要

The present invention provides a multilayer insulated electric wire to achieve a good balance between heat resistance and voltage resistance characteristics, then satisfy IEC standards Pub. 61558 which require strict voltage regulation, and electric or electronic equipment such as transformer formed by winding the insulated electric wire. The present invention is a multilayer insulated electric wire including two or more insulating layers, wherein at least one layer of the insulating layers other than the outermost layer is an insulating layer containing a resin having a melting point of 200°C or higher and a tensile modulus of elasticity at 25°C of 1000 MPa or less, and the multilayer insulated electric wire is coated with a resin material (also simply called a resin) having a tensile modulus of elasticity at 25°C of 1000 MPa or more as the outermost layer, and electric or electronic equipment such as transformer formed by winding the insulated electric wire.
