Product Advantages
Compliance with automotive industry standards
Certified under the IATF 16949 automotive quality system, meeting the reliability requirements of new energy vehicles.
Lightweight design
Aluminum magnet wire products are 30% lighter than copper, helping reduce overall vehicle energy consumption.
Excellent high-frequency performance
Litz wire reduces losses by 40% in high-frequency applications (10 kHz–1 MHz), improving OBC charging efficiency.
Resistance to harsh environments
Resistant to vibration and high–low temperature impact (-40℃ to 180℃), suitable for the complex operating conditions of automobiles.
Technical Highlights
The independently developed low-loss flat enameled wire is produced using imported MAG (Austria) equipment. The enamel film uniformity error is ≤±0.01 mm, and the scratch strength is ≥15 N, meeting the high-speed operation requirement of 15,000 rpm for new energy vehicle drive motors. Litz wire products have been successfully applied to high-end models of leading domestic automobile manufacturers, supporting the achievement of a 200 km driving range with 10-minute fast charging.
