0.004mm-1.00mm UEHN overcoat polyamide enamelled wire UEHN U3 Thermal class 180
U2 and U3 are double-layer and triple-layer windings respectively, which are more suitable for higher power and current applications and have better electromagnetic shielding performance.
1. Extremely high heat resistance: UEHN is heat resistant up to 180°C, making it stable and reliable for long term operation in high temperature environments. This makes it ideal for motor and transformer applications where extreme temperature conditions need to be tolerated.
2. Excellent Mechanical Properties: UEHN adopts a special polymer formulation and production process, which has extremely high tensile strength and wear resistance.
UEHN is able to withstand a wide range of mechanical stresses during the manufacture of motor stator windings.
3.Good chemical resistance: UEHN's polyimide insulation has excellent corrosion resistance to most chemicals and solvents, allowing it to work stably for a long time in harsh environments.
