What is the working principle of New Solar PV Round Wire Machine
The New Solar PV Round Wire Machine is a continuous integrated precision forming equipment, specially designed for the production of tin coated photovoltaic round copper wire (round wire welding strip) for HJT, TOPCon, BC battery 0BB non main grid technology. Using oxygen free copper wire as the substrate, relying on multiple continuous processes, drawing, online annealing, surface purification, uniform tin coating, online detection, and precision winding are completed under a constant tension system; The core relies on servo linkage closed-loop tension control to ensure the stability of wire roundness, wire diameter tolerance, and tin layer thickness throughout the entire process, producing finished products directly for interconnection of photovoltaic module cells.
