 PET Composite membrane
PET composite membrane is coated with F grade polyurethane adhesive which is made of two or more layers of polyester membrane bonded multi-storey semi-soft composite.
Characteristics
Composite of polyester membrane has excellent dielectric properties, good heat resistance low water absorption and good impact performance. Its advantage is that it can make many kinds of the geometry of the insulation tube. The electrical properties of glass fabric insulation cylinder can greatly improve.
Application
It is mainly used for high and low voltage ring insulation of the dry-type transformers. It is a large number of 3640 laminated glass tube used as a substitute for the use of insulation cylinder, It can also be used transfomers or other electrical equipment to do the used of insulation board.
The main properties are as follows in Table 1
