High-precision 3D bent hard copper bars: ideal choice for new energy fields and power systems

In new energy vehicles, energy storage equipment, and various power transmission and control systems, the requirements for current-connected components are increasing day by day. Traditional connection methods are often difficult to meet the multiple needs of complex space, large current transmission and high reliability. We focus on providing advancedHigh-precision 3D bent hard copper barandextruded hard copper bar, provide excellent connectivity solutions for your system.

Why choose high-precision 3D bent hard copper bars?

High-precision 3D bent hard copper barIt refers to the complex bending and forming of highly conductive hard copper bars according to three-dimensional space requirements through advanced CNC equipment and precision molds. This technology brings significant advantages:

• Extreme spatial adaptability: In compact battery packs, distribution cabinets or motor controllers, traditional straight lines or simply bent copper bars are often difficult to wire. 3D bending technology can accurately match any complex and irregular internal space, achieve compact and efficient layout, maximize the use of precious space, and increase system power density.
• Optimize current paths and reduce losses: Precise 3D design can plan the shortest and smoothest current path, reduce unnecessary bends and turns, thereby significantly reducing resistance and energy losses, reducing heat generation, and improving overall system efficiency.
• Excellent mechanical strength and vibration resistance: The hard copper bar itself has excellent rigidity and strength. Through precise 3D bending, better structural support and stress dispersion can be achieved, allowing it to effectively withstand the vibration and mechanical impact generated during equipment operation, ensuring long-term stability and reliability of the connection.
• Simplify assembly and improve production efficiency: The pre-formed 3D bent copper bars with high precision do not require secondary processing or adjustment on site, and can be directly installed in place, greatly simplifying the assembly process, shortening the production cycle, and reducing labor costs and potential installation errors.
• Highly customized: We can customize copper bars of various complex shapes, size, hole positions, and bending angles according to the 3D drawings provided by customers or specific needs, which perfectly meets the unique design requirements.

Extruded hard copper bars: a reliable guarantee for safety and insulation

In addition to excellent geometry,extruded hard copper barProvides additional safety and performance guarantees for your power system:

• Reliable high-voltage insulation: Through advanced extrusion process, a layer of dense and continuous high-performance insulating material (such as PVC, PE, TPE, etc.) is uniformly extruded on the surface of the copper bar. This layer of insulation can effectively isolate live parts, completely eliminate the risk of short circuit, and greatly improve system safety. It is especially suitable for high-voltage and high-current environments.
• Enhance environmental adaptability: The extruded insulation layer can effectively protect the copper bars from environmental erosion, such as moisture, dust, oil pollution, chemical substances and mechanical wear. This allows the copper bar to operate stably for a long time under harsh working conditions, extending its service life.
• Optimize spatial layout: Compared with bare copper bars, extruded insulation rows can allow for smaller electrical clearances, further achieve a compact design inside the equipment and improve power density.
• Easy installation and simplified maintenance: The pre-insulated copper bars reduce the cumbersome insulation treatment work on site and simplify the assembly process. At the same time, its good insulation properties reduce the risk of electric shock during maintenance.
