Insulation type of transformer

The temperature rise limit is defined by the insulating materials used! An introduction to the types of insulation for transformers.

Transformers are reliable and long-lasting devices, but prolonged use can lead to deterioration of the winding insulation and insulating materials due to temperature effects. They are also significantly affected by the ambient temperature in which they are used. To ensure safe long-term use, temperature rise limits are established based on the insulating materials used, and each type of insulation material has its own specified temperature rise limit. The maximum allowable temperature, under rated conditions, is the temperature rise limit of the insulation type plus the reference ambient temperature (40°C). When installed and used in control panels, it is generally necessary to consider that the internal temperature rise of the panel can be 5 to 10°C. *For more details, please refer to the PDF documentation or feel free to contact us.
