Frequently Asked Questions
Q
What copper purity is used in your flexible copper conductors?
Our flexible copper conductors use high-purity electrolytic copper wire (T1/T2 grade red copper) with a purity of ≥99.9%, ensuring excellent electrical conductivity and long-term reliability.
Q
What surface treatment options are available for the copper conductors?
We offer three surface treatment options: bare copper, tin-plated copper, and silver-plated copper. Tin plating improves solderability and corrosion resistance, while silver plating provides superior oxidation resistance and is suitable for high-frequency or demanding environments.
Q
Can the cross-sectional area and wire diameter be customized?
Yes. We offer full customization of cross-sectional area, monofilament diameter (0.05 mm – 0.15 mm), conductor shape (circular, rectangular, or custom), and precision-cut lengths based on your drawings or specifications.
Q
What industries are these flexible copper conductors suitable for?
These conductors are widely used in power systems, rail traction, industrial automation and robotics, welding and electrolysis equipment, marine engineering, new energy applications (solar PV and wind power), and building/construction systems including slip rings and lighting infrastructure.
Q
What insulation or shielding options are available?
Optional protection includes PVC insulation for general-purpose applications, silicone insulation for high-temperature environments, and metal shielding for EMI (electromagnetic interference) resistance. These options can be combined based on your application requirements.
Q
What is the available nominal cross-sectional area (CSA) range?
Our standard product range covers nominal CSA from 0.65 mm² up to 50 mm², with various strand configurations and individual wire diameters of 0.05 mm, 0.1 mm, or 0.15 mm. Custom sizes beyond this range are available upon request.
