Abstract
A pulsed voltage surge resistant magnet wire having a conductor and a continuous and concentric and flexible uniform coat of insulation material superimposed on the conductor. The insulation material has an effective amount of a particulate filler material dispersed throughout the material to increase the pulsed volt surge resistance of the insulation material by at least ten-fold in comparison testing at 20 kHz, 0.721 kV per mil, 50% duty cycle from about 30.degree. C. to about 130.degree. C. with rise times of about 83 kV per microsecond. The particulates of the filler have a size from about 0.005 microns to about 1.0 microns.
