Why overhead electric cables are made of aluminium and ...

Q.

Two wires of equal length, one of aluminium and the other of copper have the same resistance. Which of the two wires is lighter? Hence explain why aluminium wires are preferred for overhead power cables. (ρAl = 2.63 × 10'8 Ω m, ρCu = 1.72 × 10'8 Ω m, Relative density of Al = 2.7, of Cu = 8.9.)

Aluminum power cables are the top option for high-voltage applications. These cables are known for their strength, ability to conduct electricity and affordability. In this article, we will talk about the advantages of using aluminum power cables in high-voltage applications.

Great Conductivity 

One of the biggest benefits of aluminum power cables is that they conduct electricity really well. Aluminum has a conductivity level of 61% of copper, which makes it an excellent choice for high-voltage applications. Aluminum cables have less resistance than copper cables of the same size, which means they lose less energy and are more efficient. But in homes, copper is still the preferred choice, read here why do we use copper in our homes?

Durable

Aluminum power cables are also very durable. They can withstand extreme weather conditions, such as high temperatures and harsh environments, making them ideal for outdoor use. Aluminum cables are also highly resistant to corrosion, which means they can last a long time without needing to be replaced.

Another benefit of aluminum power cables is that they are cost-effective. This material is less expensive than copper, which makes Aluminum a popular choice for large-scale projects. By using aluminum cables instead of copper cables, you can save money without compromising performance.

Lightweight 

Compared to copper cables, aluminum power cables are also lighter in weight. This makes them easier to manage and install. This is especially helpful for larger projects that require thousands of meters of cable.

Eco-Friendly

Aluminum power cables are also an environmentally friendly option. Aluminum is a material that can be easily recycled, which means that old cables can be melted down and reused. This process requires less energy compared to producing new aluminum cables, making it a more sustainable option. All these benefits make aluminum cables a popular choice for projects where efficiency, cost, and durability are important.
