Different insulation materials, their insulation performance is also different. However, there are many factors that affect the insulation properties of the insulating material. Among them, the temperature is directly affected by the insulation property of the insulating material. The higher the temperature, the worse the insulation of the insulating material will be. Therefore, we need to understand that each insulating material will not affect its insulation at which temperature.


Insulating materials are usually used in electrical machinery. In order to use the motor normally, it is necessary to control the insulation strength. In order to ensure insulation strength, each insulating material has an appropriate maximum allowable working temperature. Under this temperature, it can be used safely for a long time, and the temperature will grow rapidly over this temperature. The heat-resistant grade of insulating material is generally Y, A, E, B, F, H, C and so on. Each level represents a different temperature.

In order to delay the life of insulation materials, we must pay attention to the selection of insulation material to control which temperature can be used normally. High quality insulation material, if the use of temperature is not appropriate, then its insulation performance will be greatly reduced.
