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.
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 technical specifications.
Q What industries are these flexible copper conductors suitable for?
These conductors are widely used in power systems, rail traction, industrial automation, robotics, welding equipment, marine engineering, and new energy sectors like photovoltaic and wind power.
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.
Q What is the available cross-sectional area range?
Our standard product range covers nominal cross-sectional areas from 0.65 mm² up to 50.00 mm², with various strand configurations. Custom sizes beyond this range can also be produced upon request.
