High-Quality Rigid Copper Busbar with PVC Dip Coating - China Factory & Suppliers for Power and Automotive Solutions
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 of ≥98% IACS to ensure minimal heat generation and low energy loss.
The PVC dip insulation achieves a UL94 V-0 flame retardant rating (self-extinguishing). With coating thickness ranging from 0.5mm to 3.0mm, it delivers dielectric withstand voltages between 2500V and 5000V (AC/DC for 1 minute).
The PVC dip coating is engineered to operate stably in environmental temperatures ranging from -25℃ to +105℃ with relative humidity up to 95% non-condensing.
They are widely applied for rigid and flexible electrical connections in power distribution cabinets, transformers, variable frequency drives (VFDs), EV battery packs, industrial charging systems, and other compact electrical equipment.
Under rated conditions, the designed service life is ≥20 years. We recommend regular torque and insulation checks every 6 months. Clean only with a dry, lint-free cloth and avoid using organic solvents.
Yes. In addition to standard black, red, and orange, customized colors are available for phase identification. The dip-coating process ensures uniform, defect-free coverage on complex bends without wrinkles or pinholes.
