Rigid Copper Busbar Insulated with 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.

Temperature range:  -25℃ to +105℃ (suitable for PVC dip coating)

Relative humidity:  ≤95% non-condensing

Applications:  Hard connections inside distribution cabinets, transformers, VFDs, EV battery packs, industrial chargers, etc.

Flame rating: UL94 V-0 (self-extinguishing)

Dielectric strength:  Depending on coating thickness (0.5–3.0mm), the withstand voltage ranges from 2500V to 5000V (AC/DC for 1 minute). Values can be verified upon customer request.

Designed service life ≥20 years under rated current and environmental conditions.

Recommended torque and insulation check every 6 months.

For dip-coated or PI film insulated busbars, clean with dry lint-free cloth; avoid organic solvents.
