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. excellent mechanical strength. PEWN outer nylon material has high mechanical toughness and abrasion resistance, and can effectively resist various mechanical stresses in the manufacturing process of motor stator windings.

2. good electrical performance. PEWN polyimide insulation layer thickness of up to 0.1-0.5mm, in higher voltage conditions can still provide reliable insulation protection.

3. excellent chemical resistance. PEWN not only nylon outer layer, polyimide insulation layer also has a strong resistance to a variety of chemicals and solvents, in harsh environments can also maintain good insulation properties.

Overall, PEWN is a specialty enameled wire product with excellent performance in terms of high temperature resistance, mechanical strength, insulation and chemical resistance, all of which are key indicators. It is widely used in the manufacturing of high-end electrical equipment that requires extreme working environments.

Pacific Wire & Cable Co., Ltd. (hereinafter referred to as Taidian Group) was established on April 14, 1950, providing a full range of wire and cable products, including: power cables, communication cables, optical cables, bare copper wires, bare aluminum wires, electronic wires, enameled wires, plastics, copper strips. Taidian Group adheres to the concept of honest management of "genuine and undeceiving" in Beiping Times Yongguang Wire Factory, and achieves customer first, leading quality, excellent production, research and innovation, and becomes a pioneer in the wire and cable industry.

In 1964, Taidian Group entered the international market for the first time, and successively set up subsidiaries in Singapore, Thailand, Australia, and both sides of the Taiwan Strait, and established Pacific Wire and Cable (Shenzhen) Co., Ltd. on December 25, 1995, with a registered capital of 16.6 million US dollars, a total investment of 19.6 million US dollars, and 36,000 square meters of self-purchased land. High-quality motors and other products around the assembly, the company obtained 1SO9001, 1SO14001, ISO45001, |SO50001, IATF16949 and other system certification.
