Is Aluminum Alloy Cable Copper Core or Aluminum Core?

Aluminum alloy cables are neither copper-core cables nor aluminum-core cables. Developed in markets where aluminum is used to save copper and where aluminum resources are relatively abundant, what exactly are aluminum alloy cables? This article from Shenghua Electric will introduce what aluminum alloy cables are and their conductor materials.
Section 1: Aluminum Alloy Cable Structure
Aluminum Alloy Cable Structure
Aluminum alloy cables are designed for...AA8000Series aluminum alloy materials act as conductors, incorporating materials like iron into pure aluminum and subjecting them to processes such as tight pressing and twisting, along with special annealing treatments. The alloy aluminum is treated to minimize voids.“Compression”Cleaner design reduces cross-sectional area, enhancing the cable's flexibility.

Advantages of Aluminum Alloy Cables
Alloy power cables address the shortcomings of previous pure aluminum cables, enhancing their conductivity, flexibility, creep resistance, and corrosion resistance. They ensure the cables maintain continuous performance stability under prolonged overload and overheating conditions.AA-8000 The series of aluminum alloy conductors significantly enhance the conductivity and high-temperature resistance of aluminum alloy cables, while also addressing issues such as electrochemical corrosion and creep in pure aluminum conductors.
Aluminum alloy has a conductivity that serves as a standard benchmark for commonly used material copper.IACSNo Chinese content provided.61.8%Flow rate is that of copper.79%Aluminum alloy cables, superior to pure aluminum standards, weigh approximately one-third of copper per unit volume. Based on this calculation, the length of an aluminum alloy cable with the same weight and conductivity is twice that of a copper cable. Therefore, the weight of an aluminum alloy cable with the same current-carrying capacity is about half that of copper cables. Replacing copper cables with aluminum alloy cables can reduce cable weight, lower installation costs, minimize wear on equipment and cables, and make installation easier.
