The general properties, viscosity-temperature relationship, storage stability, and heat resistance of ELAN 3322-300 HV1 epoxy impregnating resin were systematically studied. Winding bar and coil samples were made to simulate the insulation structure of high voltage motor, and their electrical performance was tested. The class H insulation structure was conducted thermal ageing tests. The results show that the ELAN 3322-300 HV1 epoxy impregnating resin has low curing volatile and good storage stability, its temperature index is 211, and its temperature classification is class H. The winding bar and coil samples after impregnating have excellent electrical insulation performance and thermal ageing resistance, and the temperature index of class H insulation structure is 182. The ELAN 3322-300 HV1 epoxy impregnating resin is suitable for VPI insulation treatment of class F and H high voltage motor.
