China Suppliers Factory Extruded Insulated Copper/Aluminum Busbar with PA12 Insulation and High Conductivity

Introducing our high-quality extruded insulated copper/aluminum busbars, designed for superior performance and reliability. Manufactured with PA12 insulation, these busbars feature a standard thickness of 0.6±0.1mm, with customizable options available at 0.7±0.15mm. Compliant with UL94 V‑0 standards, they can operate effectively in temperatures ranging from -40℃ to 150℃. In terms of electrical performance, our busbars exhibit exceptional safety with a leakage rate of less than 0.5mA at 5000V and an insulation resistance exceeding 500MΩ at 1000V. The conductivity of copper is greater than or equal to 97% IACS, while our aluminum alloy achieves over 60% IACS, ensuring optimal efficiency in electrical applications. Our state-of-the-art production processes, which include automatic/semi-automatic cutting, deburring, bending, and extrusion (with the exception of manual punching), enable us to deliver high efficiency, consistent quality, and cost-effectiveness. We pride ourselves on offering fast delivery, durable insulation, and a wear-resistant surface, all while saving valuable space. Our busbars are progressively replacing traditional stamped conductors in new energy applications, making them an ideal choice for modern electrical needs. As a leading factory and reliable supplier in China, we offer customization to meet your specific design requirements. Choose our insulated copper/aluminum busbars for your next project and experience excellence in electrical solutions.

    Product Advantages

    High-Conductivity Materials

    High-purity copper (T2, C1100, etc., ≥97% IACS) or high-conductivity aluminum alloy (6101, 1060, etc., ≥60% IACS) ensure excellent current-carrying capacity.

    Quality PA12 Insulation

    Standard thickness 0.6±0.1mm (range 0.5–0.7mm); customizable 0.7±0.15mm (0.55–0.85mm). Withstand voltage: 4000-6000V (AC/DC, 1min) at standard thickness, up to 5000-7000V at custom thickness. V-0 flame rating, -40℃~150℃ operating range, high electrical safety margin.

    Automated Manufacturing

    Except manual punching, all steps are performed by automatic / semi-automatic equipment. Compared with traditional labor-intensive stamped conductors:

    • Lead time reduced by >30% for batch orders;
    • Consistent insulation thickness and dimensional tolerances, minimal human error;
    • Lower overall cost for long-term mass production, reduced scrap rate.
    Appearance & Durability

    Smooth, glossy, highly wear-resistant, no fading or peeling, compact installation.

    Frequently Asked Questions (FAQ)

    What conductor materials are used for extruded busbars?

    High-purity copper (such as T2, C1100 with conductivity ≥97% IACS) or high-conductivity aluminum alloys (such as 6101, 1060 with conductivity ≥60% IACS) are used to guarantee optimal current-carrying efficiency.

    What are the electrical insulation specifications of the PA12 coating?

    The standard PA12 insulation thickness is 0.6±0.1mm with a withstand voltage of 4000-6000V (AC/DC, 1 min). A custom thickness of 0.7±0.15mm supports withstand voltages up to 5000-7000V, with a V-0 flame retardant rating.

    What is the operating temperature range for these busbars?

    The busbars are designed to operate safely within a temperature range of -40℃ to +150℃ with relative humidity ≤95% non-condensing.

    Where are extruded copper and aluminum busbars typically applied?

    They are widely utilized in power distribution cabinets, Variable Frequency Drives (VFDs), EV battery packs, energy storage systems (ESS), and industrial charging stations.

    What is the designed service life and how should they be maintained?

    The busbars have a designed service life of ≥25 years. Routine maintenance requires checking bolt torque and insulation integrity every 6 months, and cleaning only with a dry cloth or neutral cleaner without organic solvents.

    Do you provide custom design and technical support?

    Yes, free technical support including engineering consultations and customized drawing verification is available. Full quality and inspection reports are provided before shipment for all custom orders.
