GB/T 1981.3-2009 "Electrical Insulation Paints, Part 3: General Specifications for Thermal curing impregnating materials" is a national standard that specifies the general technical requirements for thermal curing impregnating materials. The content covers product classification (according to heat resistance grade and composition system), technical indicators (percent solids, viscosity, dielectric strength, thermal bonding force, etc.), test methods (physical and chemical performance and electrical performance testing), inspection rules and Encasement storage requirements. This standard applies to the heat curing impregnation process of insulating components such as motors and electrical coils. By standardizing the heat resistance, bonding force and insulation stability of the paint, the electrical performance and mechanical strength of the windings after impregnation are ensured. Provide technical basis for the production, inspection and selection of heat curing impregnating materials for electrical insulation, and help improve the reliability and service life of electrical equipment.
