    摘要: In order to offer the epoxy resin composition allowing much lower viscosity and higher heat resistance (glass transition temperature) of cured product to coexist and lowering hygroscopic property, and the insulation coil and one-piece impregnation type rotating machine with improved insulation performance using the composition, the epoxy resin composition made of a mixture of 1 to 5 by weight of sulfonium salt cationic polymerization initiator and 3 to 15 by weight of reactive diluent with 100 by weight of epoxy resin is provided. The insulation coil that is an insulation coil made of plain conductor wire formed into a specified shape and wound with insulation material, impregnated with the epoxy resin composition and then cured is provided. In addition, one-piece impregnation type rotating machine consisting of a stator constructed as follows and a rotor: that is, an insulation coil made of conductor formed into a specified shape and covered with insulation material is mounted into an iron core slot, and then piles and wedges are inserted into the inner circumferential grooves of the iron core slot and the insulation coil is connected at the outside edge of the iron core, and then an assembly of the insulation coil and iron core is impregnated with the epoxy resin composition and cured.
