Composite Pet Polyester Thin Film and Class F Red Coaming
Basic Info.
Product Description
Composite PET polyester thin film and Class F Red Coaming
Product Specification
PET
The composite PET polyester film is composed of a multilayer PET polyester film.
Class F red coaming used as insulating cylinder is composed of multi-layer PET polyester film and red polyester non-woven fabric..
Feature and Application
It has good electrical performance, low shrinkage, low moisture absorption and high heat resistance.
The products are mainly used between high and low pressure coil of dry type transformer, can be replaced by 3640 laminated glass pipe as soft insulating cylinder.
