11.5 kV Breakdown Voltage and High Stiffness for Motor Slot Liner and Wedge Applications
Product Overview
Motor insulation film has to do more than insulate. It has to slide into stator slots without tearing, hold its shape around wedge inserts, and survive automated winding. The 50μm PET Motor Insulation Film is made for exactly this. A hazy surface gives it excellent handling properties, and its good stiffness helps it stay in place once inserted. With an 11.5 kV breakdown voltage and balanced 249 MPa MD/TD tensile strength, it delivers the mechanical reliability motor manufacturing lines need.
