Braided Flexible Power Shunts
Products Description
Our braiding technology demonstrates significant expertise at both the micro and macro levels for Braided Flexible Power Shunts:
Dynamic Flexibility Matrix: The copper wires within the braid are woven with a specific pitch angle, ensuring extremely high degrees of freedom in the X, Y, and Z axes, effectively offsetting resonance losses during electrical equipment operation.
Ultra-Low Contact Resistance: Advanced diffusion bonding technology or high-pressure cold pressing processes ensure a tight bond at the ends, eliminating flux contamination and resistance steps associated with traditional soldering.
Skin Effect Optimization: Compared to a single thick cable, the multi-strand fine braid structure significantly increases the effective surface area, better addressing the skin effect in high-frequency applications and reducing AC impedance and heat generation.
Key Material Advantages: High Purity and Durability
The purity of the material determines the upper limit of the system's energy efficiency. We use only T2/C11000 grade high-purity oxygen-free copper:
Conductivity ≥ 100% IACS: An extremely low impurity content results in extremely low heat generation, significantly reducing the heat load on substations or energy storage cabinets.
Excellent Fatigue Resistance: Through a special toughening process, the copper wire can withstand hundreds of thousands of mechanical cycles without cracking.
Environmental Compliance: All Copper Braided Flex Connectors comply with RoHS 2.0 and REACH standards, meeting the environmental compliance audits of top global engineering clients.
Detail Showcase: The Devil Is in the Tiniest Details
Surface Texture
The braided layer has a clear, uniform, and tight texture, with no obvious "missing braids," "skipped threads," or "burrs." Whether tin-plated or nickel-plated, the surface exhibits a smooth, continuous metallic luster, free of nodules, exposed copper, or water stains.
Transition Area
No copper wire breakage due to excessive compression or loosening due to insufficient compression is observed at the end crimping joint. The interlocking teeth of the crimping die are evenly distributed and of consistent depth, and the connection between the end and the braid is as smooth as natural growth, with no abrupt changes when touched for Flexible Copper Braided Connector Bus Bar.
End Hole Precision
The mounting holes on the conductive ends are formed in a single clamping operation using a high-precision CNC machining center, with hole spacing tolerances strictly controlled at the micrometer level. This ensures that during on-site installation, multiple bolts can be inserted into the mating parts simultaneously without stress, avoiding assembly damage caused by "forced pulling."
Soft touch
When you hold the braid and bend it significantly, it feels smooth and elastic. Braided Copper Flexible Connector With Tin Ends quickly returns to its original shape after you release it. There is no dry feeling of metal friction inside, which directly confirms the thoroughness of the material annealing and the degree of release of internal stress.
Application Advantages
| New Energy Storage Systems | At the lithium battery module and pack level, Flexible Busbar and Copper Jumpers enable flexible bridging of series and parallel cell connections, absorbing displacement caused by cell expansion and contraction, while providing a low-impedance, high-current path. Its flame-retardant insulating sleeve design meets UL94 V-0 requirements, adapting to the thermal runaway protection needs of energy storage systems. |
| Rail Transit Traction Systems | In the traction converter cabinets of subways and high-speed trains, braided strips connect IGBT modules to DC buses, withstanding continuous vibration and impact during train operation. The Flexible Copper Braid Connectors are certified to the EN 50155 railway electronic equipment standard, maintaining stable performance in a temperature range of -40℃ to +85℃, 95% humidity, and strong electromagnetic interference environments. |
| High-Power Rectification and Electrolysis | Electrolytic cells in the chlor-alkali industry and metal smelting require the support of tens of thousands of amperes of DC. Braided copper strips, as inter-plate connectors, with their large cross-sectional area (up to 3000mm² or more) and excellent heat dissipation capabilities, ensure long-term reliable operation under highly corrosive and high-current-density conditions. |
| Marine Engineering | The salt spray-resistant coating and sealing structure design make the product suitable for marine environments such as marine electric propulsion systems and offshore wind power booster stations. Certified by DNV GL, it meets stringent requirements for vibration, tilting, humidity, and salt spray. |
