Direct supply from state-of-the-art production lines. Precision-engineered magnet wires for efficient transformers, motors, and high-frequency appliances.
The global demand for high-performance magnet wires—specifically soldering enamel coated wires—is witnessing unprecedented growth. Driven by the worldwide energy transition, industrial automation, and the electrification of transportation, magnet wires have shifted from standard commodities to high-tech customized assets. In today's commercial landscape, reliability at elevated temperatures and simplified assembly (via direct solderability) are key criteria for engineering teams globally.
Traditionally, copper has been the standard for electrical connectivity. However, severe copper price fluctuations and the demand for lightweight components have accelerated the adoption of enameled aluminum wires and Copper-Clad Aluminum (CCA) alternatives. Modern industrial installations require materials that balance economic viability with high conductivity and heat resistance.
Soldering enamel coated wire (often utilizing polyurethane insulation coatings like UEW) allows design engineers to automate coil termination. The insulation vaporizes clean at standard soldering temperatures (360°C to 480°C) without chemical or mechanical stripping, reducing assembly cycle times by up to 40% and eliminating risk of wire neck-down during scraping.
From micro-motors in electronics to massive wind turbine generators, the selection of the base material (copper vs. aluminum), insulation film chemistry (polyurethane, polyesterimide, or polyamide-imide), and shape (round vs. flat/rectangular) determines system efficiency, longevity, and thermal thresholds.

Choose from our specialized enameled wire categories designed to meet diverse electrical application environments.
The electrical industry is undergoing a paradigm shift towards higher voltages to increase power density and transmission efficiency. Particularly in the Electric Vehicle (EV) sector, the migration from 400V to 800V architectures reduces vehicle weight and enables ultra-fast charging. However, higher voltage systems expose magnet wires to high-frequency voltage spikes and partial discharge (corona effect), which can destroy standard insulation coatings within hours.
To combat this, the technical roadmap of enameled wire focuses on multi-layered insulation composite designs:
Furthermore, flat (rectangular) wires are increasingly replacing traditional round wires in high-power applications. Flat wire design increases the slot fill factor of motors from 45% up to 70%+, drastically reducing copper losses, winding resistance, and heat dissipation challenges. Suzou Daiming's research and development focuses on optimizing these flat wire geometries with uniform paint distribution along the sharp corner radiuses, eliminating weak points prone to voltage stress.
Understanding temperature indices is crucial: Class 130 (B), Class 155 (F), Class 180 (H), Class 200 (K), and Class 220/240 (R). Higher classes ensure structural integrity during transient overload scenarios in transformers and propulsion motors.
Delivering high-performance enameled wires with precise matching and unmatched quality assurance.
Each roll of enameled wire undergoes rigorous in-line laser inspections and eccentricity testing to ensure uniform layer thickness, minimizing dielectric breakdown risks.

Our eco-friendly formulations and production processes support high-efficiency motors, helping to lower energy consumption and carbon footprints.
All our products comply with RoHS and REACH standards and are tested to meet IEC and NEMA requirements, enabling seamless integration into global markets.
From power grids to household electronics, our enameled wires drive performance in diverse sectors.
In modern industrial design, thermal management and material costs are critical challenges. High-voltage transformers and EV traction motors operate under intensive thermal stress, requiring materials that minimize power loss and prevent thermal runaway.
Daiming’s Copper-Clad Aluminum (CCA) Solutions: Copper-Clad Aluminum enameled wire integrates the light weight of aluminum with the conductivity of copper. By utilizing a metallurgical bond where a copper sleeve is drawn over an aluminum core, CCA provides an effective alternative to solid copper. This solution reduces weight by up to 40% and lowers material costs while retaining copper's soldering ease, making it popular for high-frequency coils, automotive voice coils, and lightweight motors.
Continuously Transposed Conductors (CTC) for Smart Grids: For ultra-high voltage (UHV) power networks, winding losses in large power transformers can reduce grid efficiency. CTC technology bundles multiple enameled rectangular copper strands in a transposed arrangement, reducing eddy current losses and hot-spot temperatures. Suzou Daiming's exports of CTC conductors support grid updates worldwide, helping to build robust, modern energy networks.
