Usually the temperature grade of the polyester Round Enameled Copper Wire is 130. However, the temperature grade of modified polyester enameled copper wire can reach 155. The product has high mechanical strength, good flexibility, adhesion, electrical properties and solvent resistance.
However, class F enameled copper wire has poor thermal shock resistance and low humidity resistance. Class F enameled wire is currently China's largest production capacity, accounting for about two-thirds. Class F enameled copper wire can be widely used in various electrical, electronic, instrumentation, telecommunication equipment and household appliances.
The main differences of polyester imide enameled wire are as follows
- The temperature resistance grade is different. The commonly used polyester temperature resistance grade is 130, there are 155 and 180, but less for single-layer enameled wire; although the polyester imine enameled wire is usually 180, the part 200 can be a single coating , Can also be composite coating.
- Polyesterimide film has better chemical resistance.
- The adhesion of polyester Rectangular Enameled Copper Wire is relatively good, such as twitching, the winding performance will be relatively better.
