The main role of insulating paper is to prevent the contact between the enameled wire and the stator during the production of the motor, to damage the enameled wire, and of course to include other functions, such as separating the different potentials of the electrical equipment.
Because the equipment and environment that are usually used in insulating paper are special, the materials that make these insulating papers are also very demanding. The first and more important thing is that the heat resistance is better because the heat generated during the operation of the electrical equipment is Very large, if the heat resistance is poor, then the device will be in the case of long-term overheating equipment aging; the second is the need for insulation resistance and high compressive strength, so the use of electrical equipment in the process will not The emergence of leakage, etc .; the last is our production of insulating paper materials must also have thermal conductivity, moisture, heat and high mechanical strength and other important features
