    Frequently Asked Questions

    Q What purity level is the copper used in your transformer stranded wire?
    Our transformer stranded wire is manufactured using over 99.95% high-purity oxygen-free copper, achieving a conductivity that exceeds 100% IACS. This ensures minimal electrical losses and maximum energy efficiency for transformer applications.
    Q What cross-sectional sizes are available, and can custom sizes be ordered?
    We offer a full range of standard specifications from 10mm² to over 3000mm². In addition to standard sizes, we fully support custom orders including special cross-sections, tin-plated surfaces, and paper insulation to meet specific design and engineering requirements.
    Q What 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 is additionally covered with transformer insulating paper, providing integrated turn insulation, making it ideal for winding leads and components with specific insulation distance requirements.
    Q Which international standards does your copper stranded wire comply with?
    Our products are produced in strict compliance with GB/T 12970 and IEC international standards. We also have the flexibility to meet specific customer enterprise standards upon request, ensuring our products integrate seamlessly into your quality management system.
    Q What quality testing procedures are applied to your transformer stranded wire?
    We apply 100% testing to all key parameters including DC resistance, cross-sectional area, and strand pitch. This rigorous quality control process guarantees that every product delivered meets precise performance specifications and long-term reliability standards.
    Q Is tin plating available, and what are its benefits?
    Yes, tin plating is available as an optional process. Tin-plated copper stranded wire offers excellent oxidation and corrosion resistance, making it highly suitable for environments with elevated humidity or temperature fluctuations. It also ensures reliable long-term performance under thermal expansion, contraction, and electrodynamic shocks during transformer operation.
