A one-component low volatile epoxy insulating varnish for high voltage motor was prepared from polyester-modified epoxy and non-volatile active diluent. The physical and chemical properties, toxici-ty, and electrical properties were tested, and the electrical properties of the simulation wire bar were stud-ied. The results indicate that the insulating varnish has good performance, low odour, volatile of lower than 3%, and non-toxicity. The dielectric dissipation factor and its increment of the 10 kV simulation wire bar with the unilateral thickness of 1.8 mm can meet the application requirement, and the withstand voltage reaches 70 kV.
