ActiveSpecification for insulating materials based on mica— Part 12：Glass fabric backup epoxy dry mica tape with high porosity
以云母为基的绝缘材料 第12部分：高透气性玻璃布补强环氧少胶云母带
Application Summary AI generated
This standard specifies the requirements, test methods, and inspection rules for high-porosity glass fabric backup epoxy dry mica tape used as electrical insulation. It is applied in the manufacturing of large generators and high-voltage motors, particularly for the ground wall insulation of stator coils in power generation equipment. The tape's high porosity allows for effective resin impregnation during vacuum pressure impregnation (VPI) processes, ensuring reliable insulation performance under high-voltage and thermal stress conditions.
