❓ Frequently Asked Questions
Q1
What copper purity is used in your flexible copper braided wire?
Our flexible copper braided wire uses high-purity electrolytic copper (T1/T2 grade red copper) with a purity of ≥99.9%. This ensures excellent electrical conductivity, minimal resistance loss, and long-term reliability in demanding applications.
Q2
What surface treatment options are available for the copper braided wire?
We offer three surface treatment options: bare copper (no coating), tin-plated copper, and silver-plated copper. Tin plating improves solderability and corrosion resistance, while silver plating provides superior oxidation resistance and is ideal for high-frequency or high-temperature environments.
Q3
Can the cross-sectional area and wire dimensions be customized?
Yes. We offer full customization of cross-sectional area (CSA), monofilament diameter (0.05 mm – 0.15 mm), overall shape (circular, rectangular, or custom profiles), and cut-to-length precision based on your technical drawings or specifications. Please contact us with your requirements.
Q4
What industries commonly use flexible copper braided wire?
Flexible copper braided wire is widely used across many industries, including power distribution systems, rail and traction equipment, industrial automation and robotics, welding and electrolysis machinery, marine engineering, new energy systems (solar PV and wind power), and building/construction applications such as slip rings and lighting installations.
Q5
Is insulation or shielding available for the copper braided wire?
Yes. Optional protective coverings include PVC insulation for general-purpose use, silicone insulation for high-temperature environments, and metal shielding for EMI (electromagnetic interference) resistance. These protective options can be specified based on your application requirements.
Q6
What is the available nominal cross-sectional area (CSA) range?
Our standard product range covers nominal CSA from 0.65 mm² up to 50.00 mm², with various wire strand configurations and monofilament diameters (0.05 mm, 0.1 mm, and 0.15 mm). For sizes outside this range or special configurations, custom production is available upon request.
