Epoxy-anhydride VPI resin with low viscosity and application in 5MW permanent magnet synchronous wind-driven generators
A new type of epoxy-anhydride insulation VPI resin (JF-9955) with a very low viscosity is developed. This new kind of epoxy-anhydride VPI resin with very low viscosity can be applied for VPI coils at room temperature. The properties of bars impregnated with this resin are tested and compared with conventional Epoxy Ester-Styrene system and unsaturated polyesterimide vinyltoluene (VT) system. The results indicate that all the electrical insulation properties are much better than that of those conventional VPI systems. And this new kind of epoxy-anhydride VPI resin is used in the impregnation of stator windings for the 5MW permanent magnet synchronous wind-driven generators. The properties of coils and generators are tested, and all the results indicate that the insulation properties of the stator windings impregnated with this VPI resin are up to the designed requirements. The 5MW permanent magnet synchronous wind-driven generators treated with this epoxy-anhydride insulation VPI resins (JF-9955) have been completed and off the production line successfully in Xiangtan Electric Manufacturing Corporation Ltd.
