25.1 kV Breakdown Voltage and High Stiffness for Heavy-Duty Motor Slot Liners
Product Overview
When motor slots get deeper and winding tensions run higher, standard insulation film can struggle. The 210μm PET Motor Insulation Film is a heavy-gauge solution designed to hold its ground. It slides into stator slots without buckling, maintains its shape around wedge inserts, and stands up to the stress of automated winding. A hazy surface ensures excellent handling and anti-blocking, while the 25.1 kV breakdown voltage and balanced 190/194 MPa MD/TD tensile strength provide the electrical and mechanical reliability that heavy-duty motor lines demand.
