❓ Frequently Asked Questions
Q
What copper purity is used in your flexible copper conductors?
Our flexible copper conductors are made from high-purity electrolytic copper wire (T1/T2 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 wire?
We offer three surface treatment options: bare copper (no coating), tin-plated, and silver-plated. Tin plating improves solderability and oxidation resistance, while silver plating provides superior conductivity and corrosion resistance for demanding environments.
Q
Can the cross-sectional area and wire diameter be customized?
Yes. The cross-sectional area and individual monofilament diameter (ranging from 0.05 mm to 0.15 mm) can be fully tailored to meet your specific requirements. Length is also precision-cut according to your drawings or technical specifications.
Q
What industries are these flexible copper conductors suitable for?
These conductors are widely used across multiple industries including power systems, rail traction, industrial automation and robotics, welding and electrolysis equipment, marine engineering, new energy sectors (photovoltaic/wind power), and building construction applications such as slip rings and lighting systems.
Q
What protective or insulation options are available?
Optional protection includes PVC or silicone insulation for electrical isolation and heat resistance, as well as metal shielding for EMI (electromagnetic interference) resistance. These options make the conductors suitable for high-temperature, high-frequency, or electrically sensitive environments.
Q
What is the available cross-sectional area range for your flexible copper conductors?
Our standard product range covers nominal cross-sectional areas from 0.65 mm² up to 50.00 mm², with various strand configurations and wire diameters (0.05 mm, 0.1 mm, and 0.15 mm). Custom sizes beyond this range can also be produced upon request.
