Massive 39.6 kV Breakdown Voltage and Maximum Stiffness from a Premier PET Motor Insulation Film Manufacturer
Product Overview
When standard heavy-duty films are still not enough, engineers turn to the thickest gauge available. The 500um PET Motor Insulation Film (nominal 500um, actual 480um) is the ultimate solution for extreme environments. It is engineered for the deepest stator slots, the highest voltage classes, and the most punishing automated winding processes. Despite its extreme thickness, it retains a 244% MD elongation, meaning it can absorb immense mechanical stress without cracking. With a staggering 39.6 kV breakdown voltage, it ensures absolute dielectric safety for the largest industrial and EV motors.
