Engineered for low core losses, high filling factors, and superior thermal endurance classes (130°C to 220°C).
In the modern era of industrial transformation, the global market for Super Enamelled Copper Wire has experienced unprecedented structural shifts. Driven by the aggressive rise of Electric Vehicles (EVs), renewable energy integration, and smart grids, high-performance magnet wires serve as the essential neurological conduits for energy transformation. The international manufacturing landscape is demanding wires that not only survive but excel under ultra-harsh operating profiles—including high frequencies, elevated voltage stresses (such as the transition to 800V drive systems), and sustained thermal extremes.
Super enamelled copper wire is copper wire coated with a thin layer of specialized synthetic insulation resin, typically consisting of materials like Polyurethane, Polyester, Polyesterimide, or Polyamide-imide (PAI). This thin enamel layer prevents short-circuiting while maximizing electromagnetic field strength in motor stator and transformer coil windings. As transmission standards tighten globally, procurement officers look for exporters who provide strict compliance with IEC 60317, NEMA MW 1000, and JIS C 3203 standards to guarantee total interoperability and zero unexpected operational downtime.
"The shift toward 800V EV traction motors and ultra-high-voltage power transformers requires enamelled winding wires to offer next-generation insulation reliability, lower dielectric losses, and exceptional resistance to corona discharge."

How our localized industrial clusters and advanced raw-material processing yield unmatched cost and quality dynamics.
In China's high-technology corridor, Suzhou Daiming Electrical Materials Co., Ltd. leverages a highly optimized supply chain that integrates high-purity copper rod casting with automated enameled wire coating lines. Operating within a specialized industrial zone, we drastically minimize the transport-induced oxidization of copper feedstocks. Our localized synergy enables us to achieve high-velocity volume runs while maintaining precise control over wire dimensional tolerances (down to microns) and insulating layer uniformities.
Our facility houses 30 advanced production lines running 24/7, employing real-time online laser monitoring for outer diameter variations and high-voltage pinhole detection. This prevents surface degradation and ensures that every single batch dispatched to regions like Western Europe, Turkey, or East Asia displays identical performance profiles. The result is a highly competitive wholesale pricing structure coupled with strict adherence to ISO 9001 and ISO 14001 environmental frameworks.
For global procurement directors, Daiming eliminates risk through engineering expertise. Our team features technical specialists with over ten years of dedicated industry experience. Whether dealing with Class 130 polyurethanes for consumer device coils, Class 180 and 200 polyesterimides for industrial machinery, or Class 220 polyamide-imides for high-temperature automotive applications, we formulate solutions tailored to precise mechanical and thermal stress challenges.
How our materials meet critical engineering standards under harsh operational conditions.
Strict mechanical calibration ensures a uniform and dense paint film, eliminating dry friction points and micro-cracks during automatic high-tension winding.

A resilient raw material pipeline ensures consistent production speeds, shielding our clients from price volatility and product shipment delays.
Lower internal resistance and minimal dielectric losses directly translate into higher operating efficiency for electric motors and transformers.
Every spool undergoes dielectric breakdown checks, springback tests, and thermal overload inspections in our specialized in-house laboratory.
Where high reliability meets complex mechanical winding stress.
Global procurement of winding wires requires balancing cost efficiency with technical performance. Quality failure in magnet wires can trigger catastrophic insulation failures inside multi-million-dollar power transformers or industrial traction motors, leading to costly plant shutdowns. Buyers must evaluate potential wholesale supply partners against a stringent performance matrix:
Determining the operating environment's thermal limit is paramount. Our wire classes cover Class 130 (Polyurethane), Class 155, Class 180 (Polyesterimide), Class 200, and Class 220 (Polyesterimide coated with Polyamide-imide). Operating a motor 10°C above its rated insulation limit halves the winding's service life, making precise thermal alignment a critical design decision.
Automated winding machines subject wires to high tensile forces, twisting, and abrasion. Exporters must guarantee high surface scratch resistance and minimal springback. Flat or rectangular wires must offer perfect corner radius uniformity to ensure that the insulating film does not thin at the edges, which would compromise dielectric strength.
For high-frequency applications, insulation thickness classifications (such as NEMA Grade 1, Grade 2, or Grade 3) dictate the wire's breakdown voltage. Our online pinhole testers detect dielectric weaknesses before the wire is spooled, ensuring it meets strict international requirements.

The classification defines the thermal class of the wire's insulation coating. Class 180 wire is insulated with polyesterimide and has a maximum continuous operating limit of 180°C. Class 220 utilizes a dual-coat insulation—typically a polyesterimide base coat topped with a polyamide-imide (PAI) outer coat. This composite layer increases thermal limits to 220°C, providing superior protection against overloads, mechanical wear, and chemical erosion.
We source oxygen-free, high-conductivity copper cathodes with a purity level exceeding 99.99%. This copper is drawn into wire form under highly controlled temperature settings, preventing atmospheric contamination and preserving optimal electrical conductivity while reducing internal resistance.
CTC products consist of multiple rectangular insulated copper wires transposed in a planetary layout. This configuration reduces eddy current losses inside high-capacity power transformers, reducing heat generation and significantly increasing overall energy transmission efficiency.
CCA wire consists of an aluminum core clad in high-conductivity copper. It weighs up to 40% less than pure copper wire and reduces material costs significantly, making it an excellent choice for high-frequency coils, automotive wire harnesses, and home electronics.
