FAQ For Cu Clad Al Busbar
Why choose copper-clad aluminum busbars?
Compared to pure copper connectors, it combines the conductivity of copper with the lightweight property of aluminum, perfectly addressing the pain points of "pure copper being expensive and pure aluminum prone to oxidation." Compared to ordinary copper-aluminum transition pieces, it avoids electrochemical corrosion through metallurgical bonding technology and maintains stable resistance over a long period of use.
What is the electrical conductivity performance of the Cu Clad Al Busbar?
The electrical conductivity of our Cu Clad Al Busbar is ≥80% IACS (at 20℃). Its current-carrying capacity is designed to satisfy the requirements of high voltage and large current scenarios, making it a reliable alternative to pure copper.
How much weight reduction does the Cu Clad Al Busbar offer?
The density of the Cu Clad Al Busbar is approximately 3.6g/cm³, which is only 44% of pure copper. This lighter weight reduces overall transportation and installation costs by about 44%.
What is the working temperature range of the Cu Clad Al Busbar?
The Cu Clad Al Busbar is designed to operate safely and efficiently within a temperature range of -40℃ to 150℃, making it suitable for demanding industrial and new energy applications.
Does the copper-aluminum interface degrade over time?
No. The copper-aluminum interface utilizes metallurgical atomic bonding, which is highly resistant to vibration and corrosion. This structure ensures a reliable connection and a working lifespan consistent with pure copper.
How well does the busbar resist corrosion?
The Cu Clad Al Busbar has excellent corrosion resistance, passing the neutral salt spray test for ≥ 48 hours with no rusting occurred, ensuring stability in harsh operating environments.
