  • Method of coating electrical conductors with corona resistant multi-layer insulation
    Patent number: 6056995
    Abstract: Electrical conductor coated with a corona-resistant, multilayer insulation system comprising first, second, and third insulation layers. The first insulation layer is disposed peripherally around the electrical conductor, the second layer is disposed peripherally around the first layer, and the third layer is disposed peripherally around the second layer. The second layer is sandwiched between the first and second layers and comprises 10 to 50 parts by weight of alumina particles dispersed in 100 parts by weight of a polymeric binder.
    Type: Grant
    Filed: February 2, 1998
    Date of Patent: May 2, 2000
    Assignee: REA Magnet Wire Company, Inc.
