Various embodiments may include a solid insulation material, e.g. in tape form, the use thereof in a vacuum impregnation process, and/or an insulation system produced therewith and also an electrical machine having the insulation system, for the medium- and high-voltage sector. Some examples include rotating electrical machines in the medium- and high-voltage sector and also semifinished products for electrical switchgear. The solid insulation material and the insulation system produced therewith are characterized in that it can be produced in an anhydride-free manner, wherein the curing catalyst is, for example, an adduct of a 1H-imidazole and/or 1H-imidazole derivative with a compound containing oxirane groups.
各种实施方案可包括一种固体绝缘材料,例如带状材料,其在真空浸渍工艺中的使用,和/或用其生产的绝缘系统,以及具有该绝缘系统的中压和高压领域的电机。例如,中压和高压领域的旋转电机,以及用于电气开关设备的半成品。该固体绝缘材料和用其生产的绝缘系统的特点是可以用无酐方式生产,其中固化催化剂例如是 1H-imidazole 和/或 1H-imidazole 衍生物与含有环氧乙烷基团的化合物的加合物。
