Why are aluminum alloy cables more expensive than aluminum core cables?
Aluminum alloy conductors are made by adding alloying elements such as copper and iron to electrical aluminum. Through process adjustments, the mechanical properties of aluminum alloy conductors are significantly improved, eliminating the low elongation, poor creep resistance, and poor flexibility associated with pure aluminum conductors. This improves the connection reliability of cable systems. However, the production process is much more complex and demanding than that of electrical aluminum rods. Furthermore, aluminum alloy cables require specialized production equipment, resulting in a higher price for aluminum alloy cables than for aluminum core cables.
