PET Film for High Voltage Insulation

PET film for high voltage insulation is used in power equipment where insulation must stay dependable for years of continuous service. It forms barriers between layers, phases and live parts in dry-type transformers, reactors, switchgear, inverters and other high voltage devices, helping to keep electrical stress under control. The film’s uniform thickness and clean, void-free structure support stable performance, while its resistance to moisture, heat and aging helps limit insulation wear over time. It is also laminated with paper or nonwoven materials to make composite insulation for demanding equipment. Rolls, sheets and die-cut parts are available in different thicknesses, with samples provided for your design and testing needs.
