China Suppliers Rigid Copper Busbar with Epoxy Spray Coating - Flame Retardant & Customized from Factory

Introducing our high-quality epoxy spray coated rigid copper busbar, manufactured in China by leading suppliers. This exceptional product features a durable epoxy insulation layer ranging from 0.4 to 0.7mm in thickness and boasts a UL94-V0 flame retardant rating. Available in standard colors such as black, red, and orange, our innovative spray insulation method ensures superior integrity and an attractive appearance while providing high wear resistance and minimizing installation space. Designed for both standard and non-standard busbar specifications, our copper busbar guarantees a tightly adhered insulation layer that is free from wrinkles, bubbles, or pinholes—even at bends. This product is ideal for applications in power, automotive, and mechanical equipment, offering excellent conductivity for reliable connections. Our factory also offers customization options to meet your specific requirements based on provided drawings. Choose our epoxy spray coated rigid copper busbar for a solution that combines performance and aesthetic appeal.

    Product Details

    Product Advantages (Epoxy Spray Coated Busbar)

    High conductivity copper: C11000/C10100 copper with ≥98% IACS, low heat and energy loss.

    High-quality epoxy insulation: Thickness 0.4-0.7mm (adjustable), UL94 V-0 flame retardant (self-extinguishing).

    Uniform spray surface: Epoxy spray process ensures consistent thickness, smooth finish, no runs or particles, stable quality.

    Strong integrity: Insulation layer tightly adheres to copper; no wrinkles, bubbles, or pinholes even at bends or complex shapes.

    Attractive & wear-resistant: High-gloss surface, scratch-resistant, no fading or peeling over time.

    Space-saving: Thin compact insulation (0.4-0.7mm) – much thinner than dip coating or heat shrink, ideal for high-density layouts.

    Flexible customization: Suitable for standard and non-standard busbars; any color available (black/red/orange...).

    Operating Conditions

    Temperature range: -40°C to +130°C (epoxy outperforms PVC)
    Relative humidity: ≤95% non-condensing
    Applications: Distribution cabinets, VFDs, EV battery packs, energy storage, industrial chargers, outdoor equipment (epoxy has good weather resistance)
    Flame rating: UL94 V-0
    Dielectric strength: Based on thickness 0.4-0.7mm and epoxy dielectric strength (approx. 20-30kV/mm), withstand voltage reaches 8000V to 20000V (AC/DC for 1 minute). Reports available upon request.

    Maintenance Instructions

    Check bolt torque and insulation surface for scratches or damage every 6 months.
    Clean with dry soft cloth or mild neutral cleaner; avoid strong acids/alkalis and organic solvents (e.g., acetone, xylene) that may attack epoxy.
    Avoid prolonged exposure above 130°C. No special protection needed outdoors – epoxy offers good UV resistance.

    Service Life

    Designed service life ≥25 years. Epoxy coating provides excellent aging resistance, chemical resistance, and heat resistance.

    Frequently Asked Questions (FAQ)

    What is the copper purity used in the epoxy spray coated busbars?
    We use high-conductivity C11000/C10100 copper with ≥98% IACS conductivity, ensuring low heat generation and minimal energy loss.
    What is the insulation thickness and flame resistance rating?
    The epoxy insulation layer has an adjustable thickness of 0.4–0.7mm and is UL94 V-0 flame retardant with self-extinguishing properties.
    What is the voltage withstand capacity of the epoxy coating?
    With a dielectric strength of approximately 20–30kV/mm at 0.4–0.7mm thickness, the withstand voltage reaches 8,000V to 20,000V (AC/DC for 1 minute). Test reports are available upon request.
    What is the standard operating temperature range?
    The busbars operate reliably between -40°C and +130°C, offering superior thermal performance and UV resistance compared to conventional PVC insulation.
    What is the expected service life and maintenance routine?
    The busbars have a designed service life of ≥25 years. Routine maintenance requires checking bolt torque and inspecting surface integrity every 6 months, using dry cloths or neutral cleaners for cleaning.
    Can busbar colors and dimensions be customized?
    Yes, we provide flexible customization for standard and non-standard busbar configurations, available in various colors such as black, red, and orange.
