Analysis of the Standardized Full-Process Production of Laminated Copper Braided Copper Busbar

In the fields of new energy power distribution, power grounding, industrial control energy storage, and communication electrical support, the application scale of flexible conductive copper braided components continues to grow. Among them, the Laminated Copper Braided Copper Busbar, with its advantages of excellent flexibility, large current carrying capacity, and strong insulation stability, is suitable for high-power power connection conditions. Unlike ordinary braided copper connectors, this laminated busbar has a precise and rigorous production process, with five standardized steps from raw material selection to finished product delivery. The entire process controls conductivity, mechanical strength, and lamination adhesion, meeting the connection and assembly standards of multiple fields such as new energy, communication, and industrial power distribution.

Raw material selection and pretreatment are fundamental steps to ensure the conductivity and flexibility of the finished product. Production prioritizes the use of TU1/TU2 high-conductivity oxygen-free copper wire, with the wire diameter typically controlled between 0.10mm and 0.20mm. Incoming copper wire must be clean and free of oxidation and rust to ensure conductivity and weldability from the source. To optimize copper wire ductility, all substrates undergo annealing and softening treatment to accommodate various braiding specifications. Depending on corrosion resistance and conductivity requirements, surface modifications such as tin plating, silver plating, and nickel plating can be applied, with standard plating thickness controlled between 3-10μm. Modified substrates can be processed into tin-plated conductive connectors such as Flexible Tinned Copper Braided Connectors and Braided Copper Flexible Connectors with Tin Ends, suitable for outdoor high-corrosion electrical applications.

High-speed braiding is the core processing step for busbars, directly determining the braiding density and structural stability. Pre-treated copper wires are neatly arranged on a pay-off frame, maintaining constant wire tension throughout the process to avoid defects such as uneven braiding tension, broken wires, and misalignment. Using high-speed spindle-type braiding equipment, fine copper wires are woven at a 30°-60° angle, achieving a finished braiding coverage of ≥85%, meeting the requirements for high current conduction. Manufacturers can customize single-layer or multi-layer braiding structures based on the current-carrying cross-sectional area and installation shape, distinguishing between flat and tubular braiding forms. Flat braided structures are specifically for subsequent lamination processing. After the braided semi-finished products are uniformly wound up, they are cut to length according to the drawings to adapt to the production and processing of Flat braided shunts and Braided Flexible Power Shunts power supply components.

Hot-press lamination is the core differentiating process of Laminated Copper Braided Copper Busbar. Flat braided copper strips are alternately laminated with insulating materials such as PET and polyimide, with 2-20 layers to adapt to different current and voltage conditions. After hot-press bonding at 120-180℃ and 5-15MPa, followed by degassing curing and slow cooling, a laminated high-current copper wire braided flexible connector is produced, suitable for high-power energy storage and power distribution.

After the busbar is formed, it requires precision machining. This includes CNC cutting to remove burrs, tin-plating and silver-plating the ends to enhance conductivity and corrosion resistance, wrapping with insulation layers as needed, and then punching and bending. The finished products are Flexible Copper Braided Connector Bus Bars and Copper Braided Busbar Electrical Flexible Wire Cables, suitable for various equipment circuit connections.

Finished products must pass three factory quality inspections: electrical, mechanical, and appearance. The products must meet the following criteria: conductivity ≥98% IACS, pass a 3kV/1min withstand voltage test, tensile strength and bending fatigue test must meet standards, dimensional tolerances must be controllable, and there must be no manufacturing defects. Qualified products can be processed into categories such as Copper Braided Connectors for New Energy Vehicles, Flexible Grounding Connectors for Telecommunications, and Braided Copper Grounding Straps, adaptable to various conductive connection scenarios.
