16.6 kV Breakdown Voltage and High Stiffness for Motor Slot Liner and Wedge Applications
Product Overview
As motor insulation film gets thicker, the film has to carry more mechanical responsibility. The 100μm PET Motor Insulation Film is designed for exactly that: it has to slide into stator slots without tearing, hold its shape around wedge inserts, and survive automated winding. A hazy surface gives it excellent handling properties, and its good stiffness helps it stay in place once inserted. With a 16.6 kV breakdown voltage and balanced 240/243 MPa MD/TD tensile strength, it delivers the reliability motor manufacturing lines depend on.
