Zusammenfassung: | PURPOSE:To prevent the occurrence of any damage caused from an increase in winding speed by applying, an insulating paint having a specified amount of given ultraparticulate tetrafluoroethylene oligomer added to the resin portion of said insulating paint, to a conductor and baking the insulating paint. CONSTITUTION:A conductor is coated with an insulating paint having 0.1 to 10wt.% of tetrafluoroethylene oligomer being of an average particle diameter below 10 micrometers and of a mean molecular weight below 500 to 10,000 added to the resin portion of said insulating paint, and then baked or coated and baked via another insulating film. This results in a low coefficient of fric tion, superior wearproofness and improved heat resistance also, with high speed winding operations being kept free from any damage of the insulating film. |
