[0069] Hereinafter, the present invention will be specifically described by way of examples, but the present invention is not limited by these examples.
[0070] The types and compounding amounts of the components described in the main ingredient column of Table 1 were put into a universal mixer heated to 130° C., and mixed under vacuum for 1 hour to prepare the main ingredient.
[0071] Next, the types and compounding amounts of the components described in the curing agent column of Table 1 were placed in a universal mixer heated to 60° C., and mixed under vacuum for 1 hour to prepare a curing agent.
[0072] 22 parts by mass of the above-mentioned curing agent were mixed with 100 parts by mass of the above-mentioned main agent with a universal mixer to prepare an epoxy resin composition for impregnating coils. In addition, the empty column in Table 1 shows that there is no compounding component.
[0073] The details of each component described in Table 1 used to prepare the...
