GB/T 20113-2006
AbolishedElectrical insulation systems (EIS) - Thermal classification
电气绝缘结构（EIS） 热分级
Application Summary AI generated
This standard defines the thermal classification system for electrical insulation systems (EIS), specifying temperature classes (e.g., 130, 155, 180°C) based on long-term thermal endurance. It is applied in the design, testing, and qualification of insulation systems used in motors, transformers, and other electrical equipment to ensure reliable operation under defined thermal stress. Engineers and procurement professionals use it to select compatible insulation materials and verify compliance with thermal performance requirements.
