Frequently Asked Questions
Q
What is a Cu Clad Al Busbar and how does it differ from a pure copper busbar?
A Cu Clad Al Busbar (Copper Clad Aluminum Busbar) is a composite conductor made of an aluminum core with a metallurgically bonded copper outer layer. Compared to a pure copper busbar, it offers significantly reduced weight (approximately 40% lighter) and lower material cost, while still maintaining excellent electrical conductivity (≥80% IACS) and corrosion resistance comparable to pure copper.
Q
What is the minimum copper layer thickness available for Cu Clad Al Busbars?
The standard minimum copper layer thickness is ≥0.1mm. However, the copper layer thickness is fully customizable based on your specific application requirements, such as higher corrosion resistance demands or enhanced solderability needs.
Q
In what temperature range can Cu Clad Al Busbars be used?
Cu Clad Al Busbars are designed to operate reliably across a wide temperature range from -40℃ to 150℃, making them suitable for both extreme cold environments (such as outdoor installations in cold climates) and high-temperature industrial applications.
Q
Are Cu Clad Al Busbars suitable for new energy and photovoltaic applications?
Yes. Cu Clad Al Busbars are widely used in new energy equipment including photovoltaic inverters and energy storage battery connection lines. Their lightweight nature combined with high conductivity and strong mechanical stability make them well-suited for high-power transmission requirements in solar and energy storage systems.
Q
Can the Cu Clad Al Busbar be customized for OEM/ODM projects?
Absolutely. Full OEM/ODM customization is supported, including round wire and flat wire specifications with various diameters and cross-sectional dimensions, surface treatments such as tin plating or nickel plating, and flexible packaging options including rolls, coils, and cut-to-length pieces to match automated production line requirements.
Q
How does the corrosion resistance of Cu Clad Al Busbar perform in testing?
The Cu Clad Al Busbar passes the neutral salt spray test for a minimum of 48 hours with no rusting observed. This demonstrates strong corrosion resistance, ensuring long-term reliability and durability in demanding environments such as coastal areas, industrial facilities, and outdoor electrical infrastructure.
