    Frequently Asked Questions
    Q1What purity level of copper is used in your transformer stranded wire?
    Our transformer stranded wire is manufactured using over 99.95% high-purity oxygen-free copper (OFC), which ensures a conductivity exceeding 100% IACS. This high purity level minimizes resistive losses and maximizes energy efficiency in transformer applications.
    Q2What cross-sectional sizes are available for your copper stranded wire?
    We offer a comprehensive range of standard specifications from 10mm² to over 3000mm². In addition, we support custom orders for special cross-sections, tin-plated versions, and paper-insulated variants to meet unique engineering and design requirements.
    Q3What is the difference between standard copper stranded wire and paper-insulated copper stranded wire?
    Standard copper stranded wire is the most versatile and cost-effective option, suitable for main leads in oil-immersed and dry-type transformers. Paper-insulated copper stranded wire features an additional layer of transformer insulating paper to form integrated turn insulation, making it ideal for winding leads and applications that require specifically designed insulation distances.
    Q4What international standards does your product comply with?
    Our copper stranded wire is produced in strict compliance with both domestic and international standards, including GB/T 12970 and IEC standards. We can also accommodate customer-specific enterprise standards upon request, ensuring full compatibility with your quality management system.
    Q5Is tin plating available, and what are its benefits?
    Yes, tin plating is available as an optional process. Tin-plated copper stranded wire offers significantly improved oxidation and corrosion resistance, making it especially suitable for environments with high humidity or chemical exposure. It also helps maintain reliable electrical contact over the long-term operational life of the transformer.
    Q6How do you ensure the quality and consistency of each product batch?
    We implement 100% testing on all key parameters for every production batch, including DC resistance, cross-sectional area, and strand pitch. This rigorous quality control process ensures that every coil of copper stranded wire meets the required specifications before it leaves our facility.
