Bus Bar Ribbon

PV bus bar ribbon for TOPCon, HJT and BC modules.The Bus bar ribbon is a rectangular tinned flat strip used to connect PV strings and junction boxes, transmitting string current as the module's busbar material. Tu1 OFHC copper (≥99.97%), 0.20-0.45 mm × 4-8 mm.

Telison's standard bus bar ribbon is the workhorse current collector for high-volume PV module assembly. Produced from Tu1 oxygen-free copper (≥99.97% purity) and hot-dip tinned on a fully automatic calendered tin-plating line. The 0.20-0.45 mm thickness range covers every mainstream string ribbon spec currently shipping into TOPCon, HJT, BC, PERC and bifacial half-cell lines; the 4.00-8.00 mm width range is slit to your string pitch on demand.

What separates Telison's standard bus bar from generic PV ribbons is process consistency at scale. Our fully automatic line holds a thickness tolerance of ±0.010 mm across the 0.20-0.45 mm range. It is the ribbon of choice for module makers who need consistent cell-to-junction-box interconnection at scale.

Features

• Copper Material: Tu1, purity ≥99.97%
• Using the new technology, the copper is hotly dipped on a fully automatic calendered tin plating all-in-one machine
• Excellent conductivity: Oxygen-free copper core with a uniform tin layer gives low current-transmission loss
• Balanced mechanical properties：Low yield strength for easy bending/forming; high tensile strength for reliability
• Good solderability: Well-wetting solder coating yields full and firm solder joints
• No direct cell contact：Not soldered directly to cells, giving low thermal-stress risk
• Customization is acceptable,Test Report could be offered upon request

Specifications

• Copper Material: Tu1, purity ≥99.97%
• Solder Coating: According to customer's requirement
• Scope of Width: 4.00mm-8.00mm
• Scope of Thickness: 0.20mm-0.45mm

 

Application

Applied to string paralleling and junction-box interconnection in all conventional PV modules, covering monofacial/bifacial, half-cut/full-cell structures .High-quality copper base can ensure the bus bar excellent performance.
