Electrical insulating materials (electrical insulating varnish, resin insulators, gas insulated combined electrical equipment)
As the heart of the motor, the insulation system directly affects the reliability and operating life of the motor. The thermal breakdown of insulation caused by dielectric loss is a common 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 placed on insulation impregnating resins, which require higher heat resistance and lower dielectric loss to ensure the safe operation of motor insulation systems.
As raw materials for resin impregnation, TTA21 series products have high performance stability, excellent electrical performance, low dielectric loss, and are suitable for the insulation treatment of high-power traction motor coils and windings. VPI resin related data
