Electrical composite PET film
Electrical composite PET film is composite by two or more layers of PET film,the product with good dielectric properties and mechanical properties.Electrical composite PET film is mainly used as the insulator between high-low voltage coils in the dry type transformers, and can also be used as turn or backing insulating in the motor or other high voltage electrical equipment.
Recommended width as 1000mm,1200mm,1400mm,1500mm.Tailor-made width is available.
Storage
The product should be stored in dry, clean and well-ventilated warehouse under 30℃.The fire, heat sources and direct sunshine should be avoided.
