Under the global trend of new energy,Photovoltaic IndustryIt is entering a new stage of high efficiency, lightweight, cost reduction and quality improvement. Faced with challenges such as fluctuations in raw material prices, rising manufacturing costs, and increased system life requirements,Small sizeCopper clad aluminum stripIt is becoming a popular material in the industry.Raytron, is the technological leader in this “material upgrade revolution”.
? Technological breakthrough, breaking the traditional limitations of copper-clad aluminum materials
Copper clad aluminum was once considered an "alternative but unreliable" solution because the copper layer was too thin, the bonding was not strong, and the conductivity was unstable. However, Ruichuang has developed its own composite rolling and online detection technology.Completely solved the industry's long-term pain points:
- ?? The copper layer is firmly bonded to prevent delamination and peeling
- ? Stable conductivity, comparable to pure copper, suitable for complex working conditions such as welding
- ?? Small size precision control, thickness as low as 0.05mm, width up to 8mm, high consistency mass production
Whether used as the main welding strip or the sub-welding strip, the small-sized copper-clad aluminum strip can operate stably and is fully compatible with various photovoltaic module applications.
?? Why is the small size more valuable?
Small size is not just "thin",A concentrated test of material control, equipment accuracy and process capability:
- Save more materials and reduce costs
- More suitable for high-density component design
- Lighter and more suitable for long-distance transportation and storage
- Higher requirements for product formability, reflecting the manufacturer's technical "hard power"
Ruichuang has been engaged in composite metal strip for many years, with multiple high-precision rolling mills + automatic thickness detection system,Guaranteed dimensional accuracy of ±0.005mm, smooth edges without burrs, and stable and controllable batch production.
?? Full application coverage, exported to the global photovoltaic market
Ruichuang small size copper clad aluminum strip has been widely used in:
- EfficientPhotovoltaic welding ribbon(TOPCon, PERC, HJT components)
- Battery connector/bus strap
- New energy storage cable system
- Intelligent terminal electrical connection conductor
- Copper tape for reinforcing flexible FPC boards, etc.
It has passed CE, RoHS, ISO and other certifications and exported to Germany, Malaysia, Vietnam, India, Japan and other countries, becoming a long-term supply partner for many overseas customers.
?? Cost optimization, greater value
- ?? Compared with pure copper strip,Save raw material cost 30% or more
- ?? Lighter, reducing transportation and assembly costs
- ?? High yield delivery, reducing production defects and rework losses
