BS EN 60371-3-4 gives requirements for electrical insulating materials made by combining mica paper with a single polyester film and impregnating the mica paper with an epoxy resin. The material outlined in BS EN 60371-3-4 is supplied in a flexible state with the resin in the B-stage for final cure after application. It may be supplied in the form of sheets or rolls. BS EN 60371-3-4 covers material having nominal thickness from 0,16 mm to 0,23 mm.
Note: It is the responsibility of the user of the methods contained or referred to in this document to ensure that they are used in a safe manner.
BS EN 60371-3-4 on polyester film-backed mica paper specification is useful for:
Mica can resist temperatures up to 1000C. It is non-flammable and is low in thermal conductivity and provides mechanical strength. BS EN 60371-3-4 provides requirement for electrical insulating material based in mica. BS EN 60371-3-4 can help manufacturer of insulator material and also, equipment manufacturer who use mica-based insulators to select right material and inspect for errors.
The use of N 60371-3-4 in electrical equipment makes them safer and robust for the users based on the properties of mica.
