Why Flat Copper Dominates High-Power Transformers?
Core advantages of flat copper wire
Five reasons why flat copper wire is preferred for high-power transformers:
①90%+ fill factor (vs. 78% round wire) fits 15% more conductive material, boosting power density 10-15%.
②Skin effect control (thickness ≤2× skin depth) cuts AC loss by 5-10%.
③Enhanced cooling: Larger surface area improves heat dissipation per Fourier’s Law.
④Withstands short-circuit forces 40% better, reducing failures 30-40%.
⑤5-8-year ROI despite 5-10% higher cost, with 3-5-year extended lifespan. IEC 60076-20 compliant, reducing CO₂ by 15-20%.
