What are the differences between copper and aluminum core cables? Which one is better?

The main component of a cable is its internal core wire, and the material chosen for the core wire is often between copper and aluminum. So, what are the differences between copper core and aluminum core cables? Comparison of Aluminum Wire and Copper Wire: 1. Copper and aluminum wires have different current-carrying capacities; 2. Aluminum wire is relatively cheaper; 3. Aluminum wire is lighter; 4. Aluminum wire has lower mechanical strength; 5. Aluminum wire oxidizes very easily at the splice ends, leading to increased temperature; 6. Copper wire has lower internal resistance. Aluminum wire has higher internal resistance than copper wire, but dissipates heat faster. The main differences lie in current-carrying capacity and mechanical strength. Comparison of advantages and disadvantages between copper core cables and aluminum core cables: Copper core has lower resistivity: The resistivity of aluminum core is approximately 1.68 times higher than that of copper core; Copper core has better ductility; Copper core has higher strength: At room temperature, the allowable stress of copper can reach 20, while that of aluminum is 15.6 kgt/mm²; Copper core is more fatigue-resistant: Aluminum is prone to breakage after repeated bending, while copper is not; Copper core has better stability and corrosion...

Characteristics of AAC and ACSR

Compared to AAC and ACSR, AAAC exhibits superior anti-sag properties, better electrical performance, and better corrosion resistance due to the higher strength-to-weight ratio of aluminum alloys. It is widely used in power, telecommunications, and construction industries. Aluminum alloy stranded wire is primarily used in power transmission, cabling, overhead cables, and other power engineering projects.
