Explore our main product lines widely specified by European manufacturing partners for severe industrial conditions and high thermal classifications.
Finland is currently leading the Nordic region's drive toward zero-carbon energy and advanced electrification. With major industrial giants expanding infrastructure in wind power generation, green marine transport (such as electric cruise liners and icebreakers), and power grid modernization, the demand for ultra-reliable enameled copper wire has surged.
Finnish manufacturers require high-quality magnet wires that conform to strict European performance standards and withstand extreme environmental shifts, ranging from sub-zero Arctic temperatures to the high-heat operations of heavy-duty wind turbine generators.
Engineered for excellence, our product lines satisfy diverse voltage, heat, and space-saving mandates across energy, automotive, and automation applications.
Our enameled copper wires utilize high-purity electrolytic copper cathodes (Cu-ETP or Cu-OF) as the raw conductor base, ensuring optimal conductivity and exceptional mechanical flexibility. These are coated with advanced polymeric resins to match thermal classes up to 220°C.

Suzhou Daiming Electrical Materials Co., Ltd. is a global technology-focused enterprise specialized in high-performance winding wires. Operating out of a state-of-the-art 258,333.33 sq. ft. production site equipped with 30 fully automated high-speed extrusion and enameling lines, we export worldwide with precision and reliable quality control.
Our raw material testing, online laser diameter profiling, and mechanical stress test procedures ensure every single spool of wire meets international industrial requirements before dispatch. Backed by a team with over 10 years of R&D experience, we customize design profiles to fit demanding environments in Northern Europe.
Our commitment to material science ensures your coils, transformers, and electric motors achieve long service lives without electrical failures.
Our enameled wires feature a dense, uniform coat. This ensures excellent flexibility, high scratch resistance, and zero cracking during high-tension automatic coil winding.
Specifically formulated to work continuously under high temperature loads and overload spikes, maintaining insulation integrity even at 220°C.
We supply tightly toleranced dimensional profiles down to micrometers. This helps engineers maximize the copper packing density factor in slots.
How our custom insulated wires serve Finland's leading industrial operations.
Helsinki's shipbuilding and marine design sectors require high-voltage traction capabilities. Our enameled round and flat copper wires provide low electrical losses and robust insulation for compact, high-efficiency ship propulsion motors.
Finnish offshore wind farms operate in demanding environments. Our Class 220 double-insulated wires and Transposed Conductors (CTC) resist high thermal stress and continuous vibration, preventing premature generator failure.
To support green energy distribution, Finnish electricity networks depend on highly efficient distribution transformers. Our low-loss enameled flat wire configurations maximize power transfer and minimize core heat buildup.
We understand that procuring magnet wire from overseas requires seamless logistics, clear commercial compliance, and strict quality assurance. Daiming offers comprehensive solutions to simplify your supply chain:

For demanding wind energy components, we recommend Class 200 (PEI+PAI) or Class 220 (PI) enameled copper wires. These grades withstand high temperatures and vibration, and resist degradation from partial discharge spikes in inverter-driven systems.
All raw copper cathodes, aluminum rods, and enamel coatings are sourced from certified partners. We conduct regular third-party laboratory tests (such as SGS) to confirm that our products do not contain hazardous substances above regulated EU thresholds.
CTC consists of multiple insulated rectangular copper wires transposed to reduce eddy current losses in high-power transformers. Using CTC helps designers optimize electrical efficiency and design more compact windings.
We pack export shipments using moisture-resistant barriers, vacuum sealing, and thick wooden panels. This protects the enameled wires from temperature and humidity changes during sea transit to Northern European ports.
Yes. We offer customization for Grade 1, Grade 2, and Grade 3 insulation thicknesses according to IEC, NEMA, or JIS standards, allowing you to balance dielectrics and winding space constraints.
Production typically takes 15 to 20 days depending on the specifications. Sea freight transit from Shanghai or Ningbo to Finnish ports is approximately 35 to 45 days. Alternatively, China-Europe rail options can reduce transit times.
Flat (rectangular) enameled wire provides a higher space-filling factor, reducing empty gaps in the coil window. This improves heat dissipation and efficiency, allowing for smaller, lighter transformer designs.
Yes. Our R&D team can adjust insulating enamels and wire tolerances to meet specific operational requirements. Contact our technical department to discuss your parameters.
