The heat generated by the product will accelerate the aging of the insulating material and affect the life of the product. For a transformer, when its product temperature rise exceeds the temperature rise of its insulation class by 6°C, its life is reduced by half. Therefore, it is necessary to find a way to reduce the temperature rise of the product.
