Corona resistance wire enamel/enameled wire and corona resistance polyester imide impregnat-ing resin was prepared by nano modification technology, and corona resistance systems were formed. The organic modification treatment of nano particle and the performance of corona resistance enameled wire, corona resistance polyester imide impregnating resin, and corona resistance insulation systems were stud-ied. The results show that the organic modified nano particles are easy to disperse, and the shelf life of nano dispersed solution reaches more than one year. The corona resistance lifetime of the nano-modified corona resistance enameled wire is improved obviously, and the cohesive force and comprehensive proper-ties are good. The nano-modified polyester imide impregnating resin has low viscosity, fast curing, and high cohesive force, its heat resistance reaches grade C, and the corona resistance lifetime increases by more than 16 times. The partial discharge characteristic of the corona resistance insulation system is im-proved obviously, and the corona resistance lifetime increases by more than 15 times.
