    摘要: To improve the heat-resisting property of insulating material including a dry mica tape and impregnating varnish, to improve the electric insulation property of insulation coils and a stator coil (13) at a high temperature, and to thereby miniaturize rotating machines (15).
    A dry mica tape includes a base material, a binder resin layer A formed on the base material and including an epoxy resin and an accelerator, a mica paper layer formed in contact with the binder resin layer A, and a binder resin layer B formed in contact with the mica paper layer, including an epoxy resin, and providing a cured resin with a higher glass transition point than that of a cured resin of an impregnating varnish only by reacting with an impregnating varnish including an epoxy resin impregnated into the dry mica tape wound around a conductor.
