High-Quality Extruded Copper/Aluminum Busbar with PA12 Insulation from China Suppliers - Reliable Factory Product

Introducing our high-quality extruded insulated copper and aluminum busbar, designed for superior performance and reliability in various applications. Manufactured in our advanced factory in China, this busbar features PA12 insulation with a standard thickness of 0.6±0.1mm and a customizable option of 0.7±0.15mm. It meets the UL94 V‑0 standard and performs effectively within a temperature range of -40℃ to 150℃. Electrical specifications include leakage currents of less than 0.5mA at 5000V and an impressive insulation resistance greater than 500MΩ at 1000V. Our copper busbars boast a conductivity of ≥97% IACS, while aluminum alloys maintain a conductivity of ≥60% IACS. Our production process utilizes automated and semi-automated methods for all operations—excluding manual punching—to ensure high efficiency, consistent quality, and reduced production costs. Experience fast delivery times without compromising on reliable insulation, wear-resistant surfaces, and space-saving designs. Ideal for new energy applications, our busbars are gradually replacing traditional stamped conductors. We offer customization options according to your specific drawings to meet unique project requirements. Contact us today to partner with leading suppliers in the industry!

    Product Details

    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 in your extruded busbars?
    We use high-purity copper (T2, C1100, etc., with conductivity ≥97% IACS) or high-conductivity aluminum alloys (6101, 1060, etc., ≥60% IACS) to ensure superior electrical efficiency and current-carrying capacity.
    What are the dielectric and thermal ratings of the PA12 insulation?
    Our PA12 insulation provides standard thickness of 0.6±0.1mm (customizable to 0.7±0.15mm) with withstand voltage capabilities of 4000-6000V up to 5000-7000V (AC/DC, 1 min). It features a UL94 V-0 flame rating and operates reliably from -40℃ to +150℃.
    How does automated manufacturing benefit batch orders?
    Automated and semi-automated production lines cut lead times by over 30% on batch orders, ensure consistent insulation thickness and tight dimensional tolerances, minimize human error, and reduce total production costs.
    What is the expected service life and maintenance routine?
    The busbars are designed for a service life of ≥25 years. We recommend checking bolt torques and insulation integrity every 6 months, cleaning with a dry cloth or neutral cleaner (no organic solvents), and avoiding sustained extreme temperatures beyond 150℃ or harsh UV exposure.
    Which industries and applications are suitable for these busbars?
    They are widely applied in power distribution cabinets, variable frequency drives (VFDs), EV battery packs, energy storage systems (ESS), and industrial charging stations where high insulation resistance and low leakage currents are required.
    Do you provide custom design and technical support?
    Yes, Zhejiang Bridgold Copper Tech Co., Ltd. provides free engineering consultation and custom drawing development. Comprehensive production timelines and certified quality reports are delivered before every shipment.
