Electrical insulation materials (electrical insulation varnish, resin insulator, gas-insulated combined electrical equipment)
As the heart of the motor, the performance of the insulation system directly affects the reliability and operating life of the motor. Thermal breakdown of insulation caused by dielectric loss is a general concern of motor insulation. Especially in the insulation of variable frequency motors, the degree of insulation heating greatly exceeds that of power frequency motors. Therefore, higher requirements are imposed on the insulation impregnated resin, which requires the impregnated resin to have higher heat resistance and lower dielectric loss to ensure the safe operation of the motor insulation system.
TTA21 series products are used as raw materials for resin impregnation, with high performance stability, excellent electrical properties, low dielectric loss, and are suitable for the insulation treatment of high power traction motor coils and windings. VPI resin related data
