Flat Copper Braided Flexible Connectors
Products Description
Flat Copper Braided Flexible Connectors are constructed from multi-layered, interwoven high-conductivity copper wire (typically T2 or oxygen-free copper) to form a strip structure. The ends are connected to form integral conductive terminals via cold pressing or molecular diffusion welding.
Key structural features include:
Multi-strand fine wire braiding structure: effectively enhances flexibility while maintaining a stable conductive cross-sectional area.
Flat strip design: reduces installation space requirements, suitable for compact electrical layouts.
Integrated end-pressed structure: reduces contact resistance and avoids the loosening risk of traditional bolted connections.
Customizable length and terminal type: supports various engineering adaptation requirements such as drilling, plating, and insulation coating.
This structure essentially achieves a balance between "rigid conductivity + flexible connection," serving as an important supplement to traditional rigid copper busbars.
Manufacturing Advantages
We have been deeply involved in the copper braiding industry for many years, possessing an independent professional manufacturing base and a comprehensive quality management system. From raw material intake to finished product delivery, every process is led by senior process engineers to ensure batch consistency and traceability. Compared to industry-standard production lines, we utilize more automated specialized braiding equipment, combined with a precision tension control system, achieving braid density uniformity far exceeding conventional standards. Our manufacturing team has an average of over 12 years of industry experience, enabling us to quickly respond to various needs from sample verification to large-scale delivery. This end-to-end manufacturing advantage allows us not only to provide standard Braided Copper Flexible Connectors but also to offer seamless supply chain support for complex engineering projects.
Material Advantages: A Dedication to Purity and Refinement in Surface Treatment
| Base Material Selection | We use T2 copper (purity ≥ 99.95%) as the braiding material. Compared to ordinary brass or low-purity copper, T2 copper has extremely low resistivity (≤ 0.017241 Ω·mm²/m), ensuring that energy loss is kept to a minimum under high-current conditions. Simultaneously, the excellent ductility of copper ensures that the copper wire will not develop internal stress cracks during high-speed braiding, maintaining the integrity of the monofilament structure. |
| Surface Treatment Processes | We offer differentiated surface treatment solutions for different application environments: |
| Bare Copper | Suitable for sealed and dry environments, maintaining optimal conductivity and cost-effectiveness. |
| Tin Plating | This is our primary recommended process for industrial and new energy applications. Tin plating not only effectively prevents the copper substrate from reacting with sulfides in the air (preventing verdigris), but more importantly, it eliminates the risk of copper-aluminum electrochemical corrosion when connected to aluminum or tin-plated terminals, greatly improving the long-term stability of the connection point. |
| Nickel/Silver Plating | For high-temperature environments (such as electric furnaces and high-voltage connections in electric vehicles) or scenarios with extremely high signal transmission requirements, nickel plating provides a high-temperature oxidation barrier, while silver plating further reduces contact resistance to the minimum for Flexible Copper Braided Electrical Connectors. |
