UEWH is a magnet wire product that uses modified polyester as the
insulating material and is coated with polyimide on the outer
layer. It has the following features:
1. Excellent heat resistance:
UEWH has a heat-resistant temperature of up to 108°C, which is more
suitable for motors, transformers and other applications in
high-temperature environments. Due to the use of modified polyester
material and polyimide outer layer with higher temperature
resistance, UEWH can work stably in harsher temperature
environments and is suitable for higher temperature application
scenarios.
2. Excellent Mechanical Strength:
The polyimide material on the outer layer of UEWH has extremely
high mechanical strength and wear resistance, which is better able
to resist various mechanical stresses and wear during the
manufacturing of motor stator windings. This property gives it an
advantage in environments that are subject to frequent mechanical
stress or vibration, such as in industrial applications such as
high-power motors and large transformers. It is also suitable for
various machines, small motors, bias coils and other products with
high winding requirements.
3. Good Insulation Properties:
UEWH's modified polyester insulation can be up to 0.1-0.3mm thick
and provides reliable insulation protection at higher voltages. The
outer layer of polyimide material further enhances the insulating
properties, allowing it to maintain reliable insulation even in
harsh electrical environments.
4. Excellent Chemical Resistance:
The UEWH polyimide outer layer is highly resistant to a wide range
of chemicals and solvents, making it suitable for industrial
applications in harsh environments.
This allows it to maintain stable performance in a variety of
chemical environments, such as in chemical, petroleum, and other
industries.
Overall, copper wire is fully annealed for the best performance, and UEWH is a high-end enamelled wire product with excellent performance, in terms of heat resistance, mechanical strength, insulation, and chemical resistance. It is widely used in the manufacture of key components in industrial fields such as high-power motors and large transformers.
