Comparison between Copper Core and Aluminum Core in AISG Cable

1, Conductivity performance
Conductivity is one of the important indicators for measuring the performance of cables. Copper core cables exhibit excellent conductivity, with a much lower electrical resistivity than aluminum core cables. This means that under the same cross-sectional and current conditions, copper core cables have a smaller voltage drop and can maintain higher voltage quality. Therefore, in application scenarios that require long-distance transmission or high current loads, copper core cables can provide more stable and efficient signal transmission. In contrast, aluminum core cables have higher electrical resistivity and greater voltage drop, which may lead to signal attenuation and distortion, affecting communication quality.
2, Mechanical strength
Mechanical strength is an important indicator for measuring the durability of cables. Copper core cables have better mechanical strength than aluminum core cables. The elastic modulus and tensile strength of copper are higher than those of aluminum, making copper core cables have better resistance to bending, tension, and fatigue when subjected to mechanical stress. Therefore, in application scenarios that require frequent movement or significant mechanical stress, copper core cables are more reliable and durable. Although aluminum core cables are lightweight, their mechanical strength is relatively low, and they are prone to breakage or deformation during bending or stretching, which affects the reliability and service life of the cable.
3, Corrosion resistance
Corrosion resistance is an important indicator for measuring the stability of cables in harsh environments. Copper core cables have good oxidation and corrosion resistance, and can maintain stable electrical performance in humid, high-temperature, or corrosive environments. In contrast, aluminum core cables are susceptible to oxidation and corrosion, especially in humid environments where a thin oxide film is easily formed on the aluminum surface. Although this film can prevent further oxidation to some extent, long-term exposure may still lead to a decrease in cable performance. Therefore, in application scenarios that require long-term operation in harsh environments, copper core cables are more reliable.
4, Cost effectiveness
Cost effectiveness is an important indicator for measuring the economic viability of cables. Aluminum core cables have relatively low costs because aluminum is a relatively inexpensive metal, and aluminum core cables are lighter in weight, which can reduce transportation and installation costs. This gives aluminum core cables certain advantages in some cost sensitive application scenarios. However, it should be noted that although aluminum core cables have a lower initial cost, their service life and performance may not be as good as copper core cables, so they may require more maintenance and replacement costs in long-term operation. In contrast, although copper core cables have a higher initial cost, their excellent performance and durability make them more cost-effective in long-term operation.
5, Application scenarios
The copper and aluminum cores in AISG cables have their own applicable application scenarios. Copper core cables are suitable for applications that require long-distance transmission, high current loads, or harsh environments due to their excellent conductivity, mechanical strength, and corrosion resistance, such as mobile communication base stations, radio antenna systems, satellite communications, etc. Aluminum core cables, due to their lightweight and low-cost characteristics, are suitable for some weight sensitive or cost limited application scenarios, such as urban power distribution, building electrical engineering, industrial fields, etc.
