Aluminium isn't as good a conductor as copper is, but it's cheap, light, strong, and "good enough." In fact, aluminum is so much cheaper than copper that you can use a much thicker wire and still save money... this makes it even stronger (at the cost of making it a bit heavier) and also lowers the resistance.
Aluminum is used in transmission lines due to its lightweight and high conductivity properties. This makes it a cost-effective choice for long-distance power transmission because it can carry more electricity with less weight compared to other materials like copper. Additionally, aluminum is corrosion-resistant which helps in maintaining the longevity of the transmission lines.
Aluminum transmission lines are often reinforced with steel strands or cables to increase their strength and ability to handle tension, especially for longer spans and higher loads. The steel reinforcement provides additional support and rigidity to the aluminum conductors, improving the overall performance and durability of the transmission lines.
Silver is the best conductor of electricity, with copper a close second. Gold is third on the list followed by aluminium. Power distribution systems commonly use copper for underground power lines and aluminium for overhead lines.
Aluminium has a low density and is not corroded.
Copper has lower electrical resistance than aluminum, allowing for less power loss during transmission. Copper also has better thermal conductivity and is more durable than aluminum, leading to a longer lifespan for transmission lines. However, aluminum is lighter and more cost-effective than copper, making it a popular choice for long-distance transmission lines.

Overhead transmission lines use steel-cored stranded aluminium conductors. The steel supplies the necessary tensile strength, as aluminium is relatively weak. Copper is not generally used as it is significantly more expensive than aluminium.

Aluminium is better than steel in conducting electricity. Actually, aluminium is one of the main conductors and it is widely used in transmission lines due to its low weight and low cost.

Why are power lines an extreme hazard when you are carrying or using an aluminium ladder?
We can use DC too for the transmission system. Refer HVDC transmission system.

Its just a matter of standard. In my area, for instance, we use 13.2 KV for distribution lines, and 69 KV / 138 KV for transmission lines.

You can disconnect the 1996 Jeep transmission lines with a 9/16 open end wrench. Be prepared for transmission fluid to come out of the transmission lines.
