Core Technical Specifications

1. ‌Standard Compliance‌: Fully aligned with IEC 60317 series international specifications, and matches the product designation of PEEID2-200, a widely recognized 200-grade composite winding wire in the global electrical manufacturing industry.
2. ‌Precise Dimension Control‌: The nominal conductor diameter is 0.850mm, with tight dimensional tolerance strictly limited within ±0.005mm, ensuring consistent winding compatibility for automated high-speed coil winding equipment.
3. ‌Thermal Performance‌: Rated for continuous long-term operation at 200°C, it retains stable mechanical and insulating properties under sustained high-temperature load, far exceeding the service life limit of conventional 155-grade polyester enameled wires.
4. ‌Insulation Structure‌: The EI/AIW double-layer composite insulation system consists of a base polyester-imide inner layer and a top polyamide-imide outer layer, forming a dense, defect-free protective coating that delivers exceptional resistance to thermal shock, chemical corrosion and mechanical abrasion.
5. ‌Electrical Performance‌: It features a minimum breakdown voltage of over 5000V, ultra-low high-frequency dielectric loss, and excellent resistance to partial discharge, making it highly reliable even under variable frequency and high-voltage operating conditions.

At Zhengzhou Tasuu Winding Wire Industry Co., Ltd., every 0.850mm EI/AIW-2/200 winding wire undergoes a full-process precision manufacturing workflow. The production starts with 99.99% high-purity oxygen-free copper rods, which are drawn through 12 consecutive precision die sets to ensure the conductor diameter deviation is strictly controlled within ±0.005mm, eliminating the dimensional inconsistency that may cause uneven winding tension. The double-layer insulation coating is applied with a closed-loop automatic painting system, which dynamically adjusts the paint viscosity, baking temperature and line speed in real time, ensuring no pinholes, bubbles or uneven thickness on the entire length of the wire.

The full quality inspection system covers every key link: online laser diameter detection runs 24/7 to screen out unqualified products, the high-voltage pinhole detector scans the full length of the wire at a speed of 300m/min to eliminate insulation defects, and the finished product sampling test strictly follows IEC 60317 standards to verify thermal shock resistance, softening breakdown temperature, solvent resistance and adhesion performance. All batches are equipped with complete test reports, which can be directly connected to the quality traceability system of global electrical equipment manufacturers.

Market & Application Compatibility

This 0.850mm PEEID2-200 winding wire has excellent compatibility with mainstream automatic winding equipment on the market. Its smooth and wear-resistant outer coating will not scratch or peel off during high-speed winding, and it can maintain stable insulation performance even in dense, sharp-angle winding scenarios. It has been widely used in new energy vehicle drive motor stators, high-power industrial frequency converter coils, aerospace auxiliary transformers and other core components, helping end products achieve higher power density, longer service life and lower failure rate under extreme operating conditions.
