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.

Is aluminium transmission lines reinforced with steel cable?
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.
What type of metal is a great conductor of electricity?
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.
Why do we use aluminium casing?
Aluminium has a low density and is not corroded.
What are the advantages of using copper compared to aluminium for transmission lines?
Copper is a better conductor than aluminum. Two wires with the same cross-sectional area, or any two constructs with the same physical shape and size, one fabricated from aluminum and the other from copper, the one made of aluminum always has higher ohmic resistance.
What metal do you use for a drawer handle?
aluminium
What are the different types of conductors used in transmission?
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.
What types of wire are used in transmission lines?
Stranded aluminium, with a steel core.
What is a better conductor steel or 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.
Is aluminium transmission lines reinforced with steel cable?
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.
Is aliminium an insulator or conductor?
Aluminium is a good conductor of electricity. It is widely used in electrical wiring and transmission lines due to its conductive properties.
Why are power lines an extreme hazard when you are carrying or using an aluminium ladder?
Why are power lines an extreme hazard when you are carrying or using an aluminium ladder?
Is aluminium conductor or semi conductor?
Aluminum is a conductor of electricity. It is commonly used in electrical wiring and transmission lines due to its high conductivity.
What type of metal is a great conductor of electricity?
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.
Why dc supply cannot be given to transmission lines?
We can use DC too for the transmission system. Refer HVDC transmission system.
What metal is transmission case on a 1996 dodge stratus?
Aluminium.
Why 22kv 11kv 33kv 132kv 220 kv are standard transmission voltages in transmission lines why not 20kv 10kv etc?
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.
Where does electricity go after it goes to the wooden overhead lines?
Overhead distribution lines are made of aluminium not wood.
