INSULATING TAPE FOR THE WINDING OF AN ELECTRIC MACHINE

摘要

An insulating tape for the winding of an electric machine, in particular a rotary machine, consists of an electric breakdown-resistant material, such as mica, of a support material such as glass silk and of a thermoplastic adhesive for holding together the insulating tape. The adhesive consists of a thermoplastic material having a continued use temperature lower than the insulation class provided for the winding. The machine insulation has however the required mechanical and electric stability, after the winding insulation is impregnated with an hardenable resin.
