188μm PET Film for Motor Insulation
188μm PET Film for Motor Insulation from Jinlu Film is a hazy polyester film for large, high-voltage motors and generators where 23.5 kV of dielectric strength is needed. At this gauge the film combines real structural body with a hazy matte surface that grips the slot wall during insertion, and a 179% MD elongation that lets it take the bends and folds of heavy winding without cracking. It is the grade that handles the tough end of motor insulation work.
