Fabricant leader de barres omnibus en cuivre tressées flexibles

Our flexible braided copper busway adopts multi-directional spiral braiding technology, which can be freely bent and twisted within the range of ±180°, breaks through the space limitation of the traditional rigid conductor, and supports the completion of wiring installation within the ultra-narrow gap of 20mm. Through the three-dimensional braided structure design, the product can effectively absorb more than 90% of the mechanical vibration in the operation of the equipment, and maintain stable conductivity in the dynamic stress environment, the service life of the conventional products to enhance three times.

Different from the standard product suppliers, we have built a customized development system from design to production: we support the customization of cross-sectional area (1.5-6000mm²), weaving density (24 spindles to 128 spindles), protection level (IP44 to IP68) and other dimensions, and we can integrate special treatment processes such as tin plating/nickel plating/fluorocarbon coating. Currently, it has been successfully applied in new energy vehicle battery module (realizing 1200A/mm² current-carrying density), flexible joints of industrial robots (resisting 100,000 times of bending) and dynamic tracking system of photovoltaic power station (resisting -40℃ extreme cold environment), providing precise conductive solutions for 200+ customers.

Production Process with Flexible Braided Copper Busbars

1. Raw material treatment

• Electrolytic copper is melted into copper rods through the upper lead furnace, and then made into copper wires through continuous casting and rolling process.

2. Braiding and molding

• Copper wire is braided into flat or cylindrical structure by multi-spindle braiding machine to ensure flexibility and even flow.

3. Welding and crimping

• Diffusion welding or cold crimping is used to connect the copper tube terminals at both ends to ensure the tightness of the joints.

4. Surface treatment

• Plating process: optional tin, nickel or silver plating to enhance corrosion resistance (tin plating is low cost, nickel plating is salt spray resistant up to 240 hours).
• Mechanical polishing: alternative to pickling to avoid corrosion residue, to ensure a matte functional surface.

5. Insulation and Inspection

• Wrap PVC heat shrink tubing or impregnated with insulating paint for voltage resistance test (e.g. 3500VDC leakage ≤ 0.025mA).

Surface Treatment For Flexible Braided Copper Busbars

1. Plating Options

• Tin plating: low cost, excellent conductivity, but easy to oxidize and change color, need regular maintenance.
• Nickel plating: strong corrosion resistance, suitable for high salt spray environment, but conductivity is slightly inferior
• Antioxidant coating: environmentally friendly surface treatment, such as silicone film, both anti-corrosion and conductivity.

2. Processing technology

• Thermal plating: metallurgical bonding, strong bonding force, suitable for simple structures.
• Electroplating: Suitable for complex shapes, but need to avoid crevice corrosion caused by pickling.

Product Advantages For Flexible Braided Copper Busbars

1. High conductivity: copper purity ≥99.95%, low resistivity, reduce transmission loss.
