Winding insulation applied with a single vacuum pressure impregnation |
摘要 |
<p>The present invention is designed to provide an insulation coil with high insulation reliability using a dry mica tape, an integral impregnation coil and a mica tape for the electrical rotating machines using these coils, said mica tape having a long shelf life and capable of preventing run-off of the impregnating epoxy resin composition during curing, with the cured product of said epoxy resin composition being high in heat resistance. It is also envisaged to provide a single insulation coil using a mica tape containing epoxy adduct imidazole as an epoxy resin curing catalyst or a mica tape containing a mixture of epoxy adduct imidazole and zinc naphthenate. An integral impregnation coil made by using said insulation coil and an epoxy resin composition, and the electrical rotating machines using such coils are also provided.</p> |
