existPhotovoltaic welding ribbonIn the continuous pursuit of "lighter, thinner, stronger", materials and manufacturing processes have become the core factors that determine system stability and long-term power generation efficiency. Faced with the high cost of traditional pure copper strips and the poor conductivity of aluminum strips,RaytronSmall size copper clad aluminum flat wireWith its technical advantages of high precision, high reliability and strong adaptability, it has become the key material choice for many photovoltaic companies' transformation and upgrading.
? Multiple performance integration, stable replacement of pure copper
Ruichuang adoptsMulti-layer composite calendering process, a high-quality copper layer is firmly coated on the aluminum substrate, effectively combining the excellent conductivity of copper with the lightweight and low-cost advantages of aluminum to achieve:
- Excellent electrical conductivity: The surface copper layer is uniform and dense, with low resistance, meeting the requirements of efficient current collection of photovoltaic welding ribbons;
- High tensile strength: The composite process has high precision, the finished product is not easy to break or delaminate, and is suitable for high-speed welding;
- Excellent thermal stability：The copper layer and aluminum are tightly combined, resistant to high temperature welding, and not easy to bulge or warp.
?? Precision control, high consistency even in small sizes
In the production of small-sized (0.05~0.2mm thickness) composite copper strips, size control is extremely difficult, but Ruichuang has:
- ? 13 high-precision rolling lines + multi-station online monitoring system
- ? Precision layer thickness control ±0.005mm, surface finish ≤Ra0.3
- ? No burrs, no warping, neat edges
This ensures that even with ultra-thin and small specifications, product consistency and high yield can be achieved in large quantities.
