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

Frequently Asked Questions (FAQ)
We utilize premium C11000 or C10100 high conductivity copper with ≥98% IACS conductivity to minimize heat build-up and energy transmission losses.
The PVC dip coating is rated for temperatures ranging from -25℃ to +105℃ and meets the UL94 V-0 standard for self-extinguishing flame retardancy.
Depending on the coating thickness (0.5mm to 3.0mm), the dielectric withstand voltage ranges between 2500V and 5000V AC/DC for 1 minute, with test reports available upon request.
Yes, standard colors include black, red, and orange for phase identification, and custom colors or specific thicknesses (0.5–1.5mm standard or up to 3.0mm) can be tailored to your technical requirements.
The product has a designed service life of ≥20 years under rated conditions. Regular maintenance involves a routine torque and insulation check every 6 months and surface cleaning with a dry, lint-free cloth (avoiding organic solvents).
They are widely applied in distribution cabinets, power transformers, VFDs (variable frequency drives), EV battery packs, industrial charging stations, and compact switchgear systems.
