Braided Flexible Copper BusBar
In the wave of industrial electrical systems upgrading towards high power, miniaturization, and intelligence, the performance limits of conductive connectors directly determine the stability, energy efficiency, and operation and maintenance costs of the overall system.Braided Flexible Copper BusBar (also known as copper braided busbars, flexible braided copper bars, or flexible power braided wires), as a core component breaking through the limitations of traditional rigid conductors, offer a conductive solution with both high conductivity and dynamic adaptability for high-current scenarios due to their unique structure of precision braiding of multiple strands of fine copper wires. They are widely adaptable to various power transmission needs requiring flexible bending, expansion and contraction compensation, or vibration environments, making them the preferred conductive connector in fields such as new energy, rail transportation, and industrial control.

Product Introduction
Braided Flexible Copper BusBar are flat, highly flexible conductive components made of hundreds to thousands of ultra-fine tin-plated soft copper wires precisely braided at high density. They combine the high current carrying capacity of near-solid copper busbars with the excellent bending performance of cables. Designed to address challenges in electrical systems such as thermal expansion and contraction, mechanical vibration, space constraints, and dynamic displacement, they are widely used in new energy, rail transportation, industrial automation, and medium- and high-voltage power distribution. Compared to traditional connection methods, their dense structure, low contact resistance, convenient installation, and reliable lifespan make them an ideal solution for modern high-reliability power connections.
Production process
Precision manufacturing enables high-end performance.
Precision Copper Wire Drawing Process
Utilizes cold-drawing technology to process T2 oxygen-free copper, with intelligent temperature control ensuring performance, precise control of individual wire tolerances, and pre-treatment to remove oxide impurities, laying a solid foundation for subsequent processes.
Multi-directional Intelligent Weaving Process
Relying on a fully automatic weaving machine, employs spiral weaving technology, adjusting density and texture as needed, and monitoring tension in real time to ensure a uniform, dense mesh structure without broken or skipped wires for Braided Copper Wire.
Solderless Cold Press Connection Process
Replaces welding with cold pressing, using precision molds for pressure bonding to avoid high-temperature damage. After grinding and testing, joint resistance is reduced, improving current-carrying stability for Braided Flexible Busbar.
Comprehensive Finished Product Inspection Process
Covers bending fatigue, salt spray, and temperature rise tests, adhering to dual-system standards. Test reports are generated for each batch, achieving quality traceability and environmental compliance for Braided Copper Bus Bar Heat Shink PVC Sleeves.
Material advantages
Using ≥99.95% pure T2 oxygen-free copper with conductivity exceeding 101% IACS, significantly reducing line loss and temperature rise. Its low-oxygen properties prevent high-temperature embrittlement, and its elongation exceeds 35%, making it suitable for repeated bending applications for Braided BusBar.
Braided Flexible Busbars can be customized with tin, nickel, or silver plating as needed to enhance oxidation resistance and abrasion resistance, effectively reducing contact resistance. The cyanide-free manufacturing process complies with RoHS and REACH regulations, meeting international environmental export requirements.
Combined with heat-shrink tubing, fluorocarbon coating, and other insulation structures, the protection level reaches up to IP68. Temperature range: -40℃ to 180℃, suitable for harsh conditions such as humidity and salt spray for Flat Copper Braids.
