22、: Glass-backed mica paper with an epoxy resin binder for post-impregnation (VPI) 1 Scope This part of IEC 60371 gives requirements for electrical insulating materials made by combining mica paper with glass fabric and bonding them together with a small amount of epoxy resin. The material is supplied
23、 in a flexible state and is designed for use in conjunction with vacuum pressure impregnation (VPI) with compatible impregnates. The final cured properties will be primarily dependent on the VPI resin used. Two bond contents are specified: low bond with a resin content of (8 3) %; medium bond with a
24、 resin content of (16 3) %. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based
25、on this specification alone. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
