China Suppliers Factory Rigid Copper Busbar with PVC Dip Coating for Power and Automotive Applications
Product Advantages (PVC Dip Coating)
High conductivity copper: C11000 or C10100 copper with ≥98% IACS, low heat generation and energy loss.
High-quality PVC dip insulation: Coating thickness 0.5-1.5mm, UL94 V-0 flame retardant rating for safety.
Low cost & batch friendly: Simple and efficient dip coating process, low material cost, ideal for mass production and non-standard shapes.
Appearance & wear resistance: Smooth, attractive surface with strong adhesion; highly wear-resistant and long-lasting.
Defect-free forming: No wrinkles, bubbles, or pinholes even at bends or complex geometries.
Space saving: Thin insulation layer occupies minimal installation space, perfect for compact equipment.
Custom colors: Standard black, red, orange; other colors available upon request for phase identification.

Frequently Asked Questions (FAQ)
We utilize high-grade C11000 or C10100 copper with electrical conductivity ≥98% IACS, ensuring minimal electrical loss and low operating heat generation.
The PVC dip insulation complies with the UL94 V-0 self-extinguishing flame retardant rating. Depending on the coating thickness (0.5–3.0mm), withstand voltages range from 2500V to 5000V AC/DC for 1 minute.
Yes, standard colors include black, red, and orange. Custom colors are available upon request to facilitate phase identification and system layout.
The dip coating operates reliably across temperatures from -25℃ to +105℃ and relative humidity up to 95% non-condensing, suitable for EV battery packs, switchgear, and VFDs.
With an expected design life of ≥20 years, we recommend a torque check and visual insulation inspection every 6 months. Clean surfaces with a dry lint-free cloth and avoid organic solvents.
Yes, we provide free engineering consultations, custom 2D/3D drawing development, and full quality/test reports prior to shipment.
