Customized Extruded Copper/Aluminum Busbar with PA12 Insulation - China Suppliers & Factory Direct Products

Introducing our high-quality extruded insulated copper and aluminum busbars, designed for superior performance in various applications. Manufactured in our state-of-the-art factory in China, these busbars feature PA12 insulation with a standard thickness of 0.6±0.1mm and an option for customization at 0.7±0.15mm. Our products are compliant with UL94 V‑0 standards and can operate in extreme temperatures ranging from -40℃ to 150℃. When it comes to electrical performance, these busbars ensure leakage of less than 0.5mA at 5000V and an impressive insulation resistance of over 500MΩ at 1000V. The copper conductivity is guaranteed to be ≥97% IACS, while our aluminum alloy conducts at ≥60% IACS, making them reliable for various energy applications. Our manufacturing processes, except for manual punching, are primarily automatic or semi-automatic. This not only enhances efficiency but also guarantees stable quality while keeping costs competitive. We offer fast delivery, reliable insulation, a wear-resistant surface, and a space-saving design, making our busbars an ideal choice for modern energy solutions. As leading suppliers in the industry, we provide customizable options based on your specific drawings, ensuring that you receive a tailored product to meet your needs. Upgrade to our advanced busbars today and experience the benefits of innovative design and manufacturing excellence from China.

    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.
    Product Display

    Frequently Asked Questions
    What conductor materials are used in your extruded busbars?
    We utilize high-purity copper (T2, C1100 with ≥97% IACS conductivity) and high-conductivity aluminum alloys (6101, 1060 with ≥60% IACS conductivity) to guarantee optimal current-carrying performance.
    What are the electrical ratings and properties of the PA12 insulation?
    The PA12 insulation features a UL94 V-0 flame rating and handles temperatures from -40℃ to 150℃. It provides withstand voltages of 4000–6000V (standard thickness) and up to 5000–7000V (custom thickness), ensuring high electrical safety margins.
    What are the primary application fields for extruded busbars?
    They are widely applied in power distribution cabinets, Variable Frequency Drives (VFDs), EV battery packs, renewable energy storage systems, and heavy industrial charging infrastructure.
    What is the designed service life of the busbars?
    The extruded busbars have a designed operational service life of ≥25 years, enabled by PA12's superior resistance to aging, hydrolysis, and environmental wear.
    Can insulation thickness and shapes be customized?
    Yes, we provide custom insulation thicknesses (e.g., 0.7±0.15mm) and custom bending/punching dimensions tailored to your drawings and engineering specifications.
    What maintenance is recommended for these busbars?
    Inspect bolt torque and surface integrity every 6 months. Clean using a dry soft cloth or neutral cleaner, avoiding aggressive organic solvents such as acetone or toluene.
