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

Used as slot insulation and between commutator segments.

Providing barriers between high-voltage windings. gost 25045

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

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

Resistance to bending, compression, and shearing. Industrial Applications

The standard outlines several parameters to ensure safety and performance in electrical machinery: What is GOST 25045

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:
