Yusheng H-class insulated wire is the first domestic enterprise that has passed ANSI AMMI ES60601 certification, and also passed UL2353, UL60601, UL60950 certification. It took us a long time to successfully develop this project. At present, there are not many available materials at home and abroad that have reached the H level. The Yusheng team has been able to develop successfully after numerous preliminary designs and multiple samples.
