A process can be used for preparing polyether-modified polybutadienes. The process involves reacting at least one polybutadiene (A) with at least one epoxidizing reagent (B) to give at least one epoxy-functional polybutadiene (C). The at least one epoxy-functional polybutadiene (C) is then reacted with at least one hydroxy-functional compound (D) to give at least one hydroxy-functional polybutadiene (E). The at least one hydroxy-functional polybutadiene (E) is finally reacted with at least one epoxy-functional compound (F) to give at least one polyether-modified polybutadiene (G).

A resin producing method is a method of producing a resin with which an insulating structure formed on an outer peripheral portion of a conductor is impregnated, the method including: a filler mixing step of mixing a nanofiller at a ratio of 15 wt % or more with an epoxy resin to form a mixture; a shear mixing step of causing the mixture to be subjected to shear mixing; a diluent mixing step of mixing a reactive diluent that reduces a viscosity of the epoxy resin, with the mixture after the shear mixing step; and a curing agent mixing step of mixing an acid anhydride curing agent with the mixture after the diluent mixing step.
