Product Description

Wholesale Class B Polyester Film Electrical Insulation Paper for Motor Coil Winding


Class B Polyester film electrical insulation paper is a reliable and versatile insulation material that can be used in a variety of electrical applications.
 
Polyester film electrical insulation paper is made of a thin layer of polyester film that is coated on both sides with a layer of electrical-grade paper. The combination of polyester film and electrical-grade paper provides excellent electrical insulation and mechanical strength.
 
We can provide B-grade, F-grade, H-grade series insulating materials including varnish, insulating paper (insulating soft composite foil), insulating impregnated products, etc.

Polyester film electrical insulation paper is commonly used in transformers, motors, and other electrical equipment as a dielectric material. It is also used as a wrapping material for electrical cables and wires.
 
The advantages of using polyester film electrical insulation paper include its high dielectric strength, low moisture absorption, and excellent resistance to chemicals and oils. It is also a cost-effective option compared to other types of insulation materials.
