たことを特徴とするコイル。 As stator winding insulation for high-voltage rotating electric machines, mica sheets with aggregated mica powder adhered to one side of polymeric films such as polyester films on the enamel coating of rectangular enameled wires, or non-woven fabrics or woven fabrics with excellent impregnation properties such as glass fibers are used. Using an insulated wire made by winding a mica sheet with laminated mica powder adhered to one side of the cloth, only the coil end part, excluding the straight part that is housed in the core slot of the form-wound coil, has excellent impregnation properties. A tortoise-shell shaped coil wound with a laminated mica sheet is made of glass fiber woven fabric with excellent corona resistance, dielectric strength and resin impregnation, or a mica sheet with laminated mica powder adhered to one side of a non-woven fabric is specified according to the applicable voltage class. They are stacked one on top of the other in a U-shape, placed in a core slot, wrapped in U-shaped insulation, fixed with a wedge, impregnated with synthetic resin such as epoxy resin, and hardened to form an integrated structure. Features a coil.
