Best Wire is made from oxygen-free copper core base, offering exceptional electrical conductivity combined with guaranteed elongation and yield strength. Sunwire's softness reduces cell breakages and electrical resistance in PV modules.

• INTERCONNECT Flat Ribbon ,Round Wire And Busbar

PV RIBBON is hot dip solder coated copper conductor of flat shape used in photovoltaic solar panels.

There are two type of PV Ribbon :

THE INTERCONNECT OR TABBING RIBBON The interconnect ribbon is solder directly onto silicon crystal to interconnect solar panels. The interconnect ribbon carries the current generated in solar cells to the ribbon.

Over organization is Roller from high purity oxygen free copper round wire and is hot-dip tinned. This state of the manufacturing technology guarantees consistent quality. we provide all typical coatings, including silver based and RoHs compliant lead free-coating.
