  • Insulation of high thermal conductivity and apparatus containing same
    Patent number: 5710475
    Abstract: Metallic conductors of electricity, such as stator bars in turbine generators, are coated with an insulating composition comprising a high temperature-resistant thermoplastic resin, such as a polyimide or polyethersulfone, having uniformly dispersed therein boron nitride or aluminum nitride in a proportion effective to provide a high thermal conductivity. Boron nitride is preferred by reason of its extremely high thermal conductivity, viscosity-decreasing properties and other advantages.

  • Extruding thermoplastic insulation on stator bars
    Patent number: 5650031
    Abstract: An apparatus and a method provide for the extruding of thermoplastic insulation onto complex shapes, such as generator stator bars. The method of the present invention comprises the steps of feeding the complex shape through a central bore of an extrusion die to deposit a thermoplastic coating along the entire length of the shape as the extrusion die traverses the length of the complex shape.
