Electrically Insulated Conductors And Methods For Electrically Insulating Conductors

Abstract

Disclosed herein are exemplary embodiments of electrically insulated conductors and exemplary methods for electrically insulating conductors, such that the resulting electrically insulated conductors are resistant to partial discharge (PD), and thereby suitable for PD resistant design schemes (e.g., 800 V or above electric motors, etc.). An exemplary method includes applying an enamel coating along an electrical conductor, wrapping an electrically insulative tape around the enameled electrical conductor, and heating sealing the tape-wrapped, enameled electrical conductor to help ensure good adhesion of the electrically insulative tape to the enamel coating. The electrically insulative tape comprises polyimide and a sufficient amount of an electrically insulative, corona resistant filler for PD resistance. The tape-wrapped, enameled electrical conductor is resistant to partial discharge (PD), e.g., suitable for use in a stator winding of an 800 volt or above electric motor, etc.
