常见问题
Why choose CCA-70% over CCA-62%?
CCA-70% offers 14% higher conductivity and 13% lower resistance than CCA-62%, making it suitable for applications requiring better electrical performance while maintaining significant cost and weight advantages over copper.
What applications benefit most from CCA-70%?
CCA-70% is ideal for high-current applications, long cable runs where voltage drop is critical, premium coaxial cables, and applications where CCA-62% conductivity is marginal.
How does the cost compare to CCA-62%?
CCA-70% typically costs 10-15% more than CCA-62% due to higher copper content, but still offers 25-30% cost savings compared to pure copper while providing significantly better performance.
