Gost 25045 Official

Used as slot insulation and between commutator segments.

GOST 25045-81 is a critical technical standard originating from the Soviet/Russian regulatory framework that specifies the requirements for , commonly referred to as micanite. These materials are vital in high-voltage engineering due to mica's exceptional thermal stability and dielectric properties. What is GOST 25045?

It defines the types of mica (such as muscovite or phlogopite) and the binding agents (shellac, epoxy, or silicone) that can be used. gost 25045

Acting as a heat-resistant electrical insulator in industrial furnaces. Why It Matters Today

Minimum voltage thresholds the material must withstand before failing. Used as slot insulation and between commutator segments

The standard outlines several parameters to ensure safety and performance in electrical machinery:

Materials are typically categorized by their heat resistance and physical form (e.g., rigid sheets for commutator segments vs. flexible tapes for coil wrapping). Technical Requirements: What is GOST 25045
