In this paper, class H insulation system of high voltage motor was studied. The basic properties of electromagnetic wire, dry mica tape, and insulating impregnated resin used in class H insulation structure were tested. The coil sample was manufactured, and the electrical properties, electric ageing, and electrothermal ageing tests were conducted on the coil sample. The results show that the insulating coil sample has excellent electrical performance in breakdown voltage and dielectric loss factor, which can meet the technical requirements of class H 10 kV high voltage motor.
