Thermal Class Insulation System

The characteristics of a given component belonging to any thermal class does not automatically mean that each insulating material used in its construction has the same thermal capacity. The temperature limit of an insulation system may not be directly related to the thermal capacity of the devices used in the system. The characteristic of any element in a specific thermal class does not properly mean that each insulating component used in its composition exhibits the same thermal capacity. It can be said that the maximum temperature limit supported by an insulation system should never be related to the thermal capacity of the materials used. In any system, the thermal performance of an element can be optimized through the protective characteristics of some materials used with this material.

The insulating system of electric motors consists of the combination of various insulating materials used in electrical equipment. This junction in an electric motor occurs through wire insulation enamel, groove bottom, groove closure insulation, insulation between phases, varnish and impregnation resin, insulation of the connecting cable and solder insulation. Other materials or components that do not come into contact with the coil are not part of the insulation system.
