From superior coating performance to sustainable green solutions — every wire we manufacture reflects our commitment to precision, reliability, and long-term partnership.
Each roll of enameled wire has undergone rigorous process and quality inspection to ensure a stable, uniform insulation layer that meets international standards — delivering consistent electrical performance batch after batch.
The enameled wire we produce has a uniform and dense paint film, strong adhesion, scratch resistance, and excellent flexibility — engineered to perform reliably in the most demanding thermal and mechanical environments.
Not only products, but also professional support. From wire diameter specifications to temperature class selection, our engineering team provides tailored technical consultation to match your exact application requirements.
With strong production capacity across 30 dedicated production lines and a complete supply chain system, we ensure on-time delivery and continuous supply — becoming a reliable long-term partner for global buyers.
Our enameled wires are used in core areas such as high-efficiency and energy-saving motors, EV drivetrains, and renewable energy transformers — actively contributing to a cleaner, more sustainable global energy ecosystem.
From standard round conductors to specialized flat and transposed formats — Daiming Electrical offers a comprehensive portfolio of enameled wire solutions across all major temperature classes.
Every enameled wire we produce follows a rigorous multi-stage manufacturing and inspection process — ensuring consistent dimensional accuracy, insulation integrity, and thermal performance in every spool we ship.
Incoming aluminum and copper rod undergoes full chemical composition analysis and dimensional verification against IEC and ASTM specifications before entering production.
Precision multi-die drawing equipment reduces conductor to exact target diameter with tolerances as tight as ±0.001mm, accommodating both round and flat wire geometries.
Multiple coating passes using polyester, polyesterimide, or polyamideimide varnishes through temperature-controlled baking ovens build a uniform, pinhole-free insulation film.
Finished wire is tested for breakdown voltage, elongation, flexibility, thermal shock resistance, and heat shock — conforming to IEC 60317, NEMA MW 1000, and JIS C 3202 standards.
Daiming Electrical's enameled wire products are exported to markets across Asia, Europe, the Middle East, and the Americas. Our dedicated export team manages customs documentation, shipping logistics, and after-sales technical support — ensuring a seamless procurement experience for international buyers.
