China Rigid Copper Busbar with Epoxy Spray Coating | Suppliers & Factory for High-Quality Insulation Solutions
Product Advantages (Epoxy Spray Coated Busbar)
C11000/C10100 copper with ≥98% IACS, low heat and energy loss.
Thickness 0.4-0.7mm (adjustable), UL94 V-0 flame retardant (self-extinguishing).
Epoxy spray process ensures consistent thickness, smooth finish, no runs or particles, stable quality.
Insulation layer tightly adheres to copper; no wrinkles, bubbles, or pinholes even at bends or complex shapes.
High-gloss surface, scratch-resistant, no fading or peeling over time.
Thin compact insulation (0.4-0.7mm) – much thinner than dip coating or heat shrink, ideal for high-density layouts.
Suitable for standard and non-standard busbars; any color available (black/red/orange...).

Operating Conditions
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℃. 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)
With a coating thickness of 0.4-0.7mm and an epoxy dielectric strength of approximately 20-30kV/mm, the withstand voltage reaches between 8,000V and 20,000V (tested under AC/DC for 1 minute). Test reports are available upon request.
The operating temperature range is -40℃ to +130℃. Epoxy spray insulation significantly outperforms standard PVC coatings in thermal stability and high-temperature resistance.
We utilize premium C11000 and C10100 high-conductivity copper with ≥98% IACS conductivity, ensuring minimal electrical resistance, reduced heat generation, and low energy loss.
Epoxy spray coating provides a thin (0.4-0.7mm), uniform, and tightly adherent finish without wrinkles, bubbles, or pinholes—even on complex bends. Its compact profile is ideal for high-density space-saving layouts.
The busbar has a designed service life of ≥25 years due to its excellent resistance to aging, chemicals, and UV exposure. It meets the UL94 V-0 flame retardant standard for self-extinguishing safety.
Yes, we provide full custom manufacturing for both standard and non-standard busbars, including custom bend geometry, punching, lead-time tracking, quality reporting, and various insulation colors (e.g., orange, red, black).
