ABSTRACT:
An electromagnetic equipment such as dynamoelectric machine includes an electromagnetic coil formed by winding an insulated wire. The insulated wire is made of a bare conductor having, on its surface, two layers of an insulating coating composed of a varnish and a low-resistance conductive coating composed of a heat resisting varnish containing a conductive oxide. A coil formed of the insulated wire is applied to the whole electromagnetic coil or a coil part near a power supply terminal.
