Abstract
A corona-resistant wire enamel composition is described comprising a polyetherimide resin and from about 1% to about 35% by weight of dispersed alumina particles of a finite size less than about 0.1 micron, the alumina particles being dispersed therein by high shear mixing. A method of providing corona resistant insulations for an electrical conductor employing the above composition and an electrical conductor insulated with a coating of the wire enamel composition are also disclosed.
Claims1
An electrical conductor coated with a corona-resistant wire enamel comprising a polyetherimide resin and containing from approximately 1% to approximately 35% by weight of alumina particles having a size from approximately 0.005 microns to about 0.050 microns, said alumina particles being dispersed through said resin by high shear mixing.
