IEC 60371-3-5:2005
Insulating materials based on mica - Part 3: Specifications for individual materials - Sheet 5: Glass-backed mica paper with an epoxy resin binder for post-impregnation (VPI)
Abstract
IEC 60371-3-5:2005 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 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 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 on this specification alone. This second edition cancels and replaces the first edition, published in 1992, and constitutes a technical revision. The main changes with regard to the previous edition include adjustments needed to align this standard with changes included in the latest edition of IEC 60371-2. Keywords: electrical insulating materials, mica paper, glass fabric, vacuum pressure impregnation (VPI)
