Abstract

851,280. Insulation for dynamo-electric machines. ALLMANNA SVENSKA ELEKTRISKA A.B. Feb. 20, 1959 [Feb. 27, 1958], No. 5863/59. Class 35. In a dynamo-electric machine H.V. winding coil comprising one or a bundle of conductors having respective portions 4 and 2, 3 shaped to be disposed in one or more slots and beyond the ends of a core not shown of the machine, the slot and end portions are insulated by a mica tape wrapping 1 filled and bound with materials which in the slot portion or portions 4 consists of a solventless resin and in the end portions 2, 3 consists of silicone rubber. The mica tape consists of mica flakes either felted together or attached by a polyester resin to a tape-shaped backing of glass fibre, paper, asbestos, or thermoplastic film of polyamide or polyethylene-glycol terephthalate. Unvulcanised silicone rubber in the form of dimethylpolysiloxane is applied on the conductor bundle end portions 2, 3 only and to each layer of wrapping tape 1 at such end portions, and to the rubber is added a silicone organic curing catalyst which vulcanises at room temperature; alternatively a heat vulcanising rubber can be used. After vulcanising the coil is dried and impregnated with either a polyester or an epoxy resin such resin entering only the slot portion 4 and being prevented by the silicone rubber from penetrating the end portions 2, 3. The coil is then wrapped in nylon or polytetrafluoroethylene tape, placed in a mould, and the resin cured. After curing, the slot portions are rigid, while the end portions remain flexible.
