Definitions

  • transformer which contains a component comprising the transformer paper.
  • the fiber composition can contain 35 to 70 wt.% of polyetherimide homopolymer fiber, polyetherimide copolymer fiber, or a combination of the foregoing, for example 40 to 70 wt.%, 50 to70 wt.%, 40 to 65 wt.%, 45 to 65 wt.%, 50 to 65 wt.%, 50 to 70 wt.%, 60 to 70 wt.% or 65 to 70 wt.% of polyetherimide homopolymer fiber, polyetherimide copolymer fiber, or a combination of the foregoing.
  • Fibrids are typically made by streaming a polymer solution into a coagulating bath of liquid that is immiscible with the solvent of the solution.
  • the stream of polymer solution is subjected to strenuous shearing forces and turbulence as the polymer is coagulated.
  • the fibrid material of this invention can be meta or para-aramid or blends thereof. More specifically, the fibrid is a para-aramid.
  • Such aramid fibrids before being dried, can be used wet and can be deposited as a binder physically entwined about the floe component of a paper.
  • the polyetherimides include a polyetherimide
  • Patent 5,227,109 which is hereby incorporated by reference, describes forming bi-component fibers in a sheath-core relationship in a spinning pack that incorporates a plurality of adjacent plates that define selected flow paths therein for a sheath component and a core component to direct the respective components into the sheath-core relationship.
  • more complex multicomponent fiber morphologies can be considered within the term core sheath as used herein, such as disclosed in U.S.
  • FIGS. 4 and 5 another type of paper-covered conductor is common heavy gauge house wiring 500, which has layers of plastic or rubber insulation 505 surrounding the common 510 and live 515 wires.
  • the ground wire 520 which is positioned between the common wire 510 and the live wire 515, optionally is covered by insulation material, as illustrated in FIGS. 4 and 5.
  • the insulation and wires are over-coated with a layer of insulation paper 523, which is over-coated by a plastic or rubber insulation layer 525.
  • Embodiment 18 The transformer component of Embodiment 16 having a porosity of greater than 0 to 774 seconds per meter column of air.
