 PV ribbon machine

 

1. Intermediate and fine wire drawing 14D Inlet 0.8-1.6mm,outlet 0.2-0.8mm

PND400-500-630 Options

 

2.PV ribbon wire 

 

2.1PV Ribbon is made from high quality oxygen-free copper. The copper is manufactured into flat copper and then tinning on the double sides. Extra-soft ribbon has higher performance than general;for instance, lower cell debris and higher conversion efficiency of solar cell.

Hot tin plating process
Stable property Environmental performance of the production processes
High elongation High tensile strength Corrosion resistance Oxidation resistance

Rolling tin integration
Lower yield strength Good solderability
Suitable for manual welding and all kinds of welding machines

PV ribbon_MBB ie Multi-Tabbing PV Wire is the newest development for the multiple Bus-bar technology. Over the years, to engineer a solder coated copper round wire for cell interconnection.Multi-Tabbing PV Wire is available in all common copper grades. including high-purity oxygen-free copper. There are no limitations regarding the available dimension you need to build the best performan- ce modules.   We have developed a solder coating process to achieve concentric coating layers to guarantee consistent soldering results in the stringing process.
