This classification is commonly denoted by letters such as A, E, B, F, H, each representing a specific maximum temperature level. In the design process of transformers, careful consideration is given to selecting an appropriate thermal class to ensure the transformer maintains excellent performance and reliability under normal operating conditions."}
