The lightness of the material allows for longer spans between supports. This in turn is a big money saving factor in the construction of transmission lines.
The type of conductor is ACSR, Aluminium Conductor Steel Re enforced. The steel in the conductor is in the center of the conductor and the aluminium conductors are wrapped around the steel.
The steel allows for the longer spans and helps prevent conductor sag on hot days or when the line is carrying a heavy connected load that will apply heat to the conductor.

Why aluminum is used to make electric wires?
Its light weight and resistnace to coorsion are important factors. The use worldwide differs. Aluminium alloy, coated aluminium wire are used. In the UK aluminium is not recommended for domestic use.
Are copper wires and not steel wires used in electric circuits although both copper and steel are electrical conductors?
Steel is not used as an electrical conductor because, although it is a conductor, it's not a very good conductor -as is copper and aluminium, for example. A steel-wire core is used, however, to reinforce aluminium conductors on transmission tower lines
Why do copper or aluminum wires generally used for electrical transmission and distribution purposes?
Both metals have a low resistance to conductivity. They are extremely flexible and do not degrade under electrical transmission as do other metals. They are less expensive than the best conductors, silver and gold.
Why are copper wires used in as connecting wires?
The copper wires used connect. Because conductivity of Cooper higher than aluminium but price of Cooper higher than aluminum. If compare between copper and aluminium cable can see at the same current rate diameter of aluminium cable is larger than copper cable.
What is metal usually used for?
Copper is frequently used for electrical wires. Aluminium is cheaper but breakable.
Why is copper used as a conductor in transmission lines?
They are the most cost effective while maintaining good conductivity for electricity. Gold is the best conductor, but is too costly to make into wires.
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.
Cables types does NOT use copper wires?
Fiber Optic cables do not use copper wires; they use either glass or plastic for the transmission medium. Aluminium is also used in certain applications, instead of copper, as it is cheaper although very slightly less conductive. I don't know the present situation, but aluminium-cored wires were introduced into the British telephone networks in the 1970s, at least for local distribution; whilst aluminium bar material was used for the main bus-bars supplying low-voltage power to the switches in the telephone exchanges.
Why are aluminium and copper used for making electric wires?
Copper and aluminum are good conductors. Other conductors like silver aren't used to make electric wires because copper and aluminum are cheaper but have the same properties.
What types of wire are used in transmission lines?
Stranded aluminium, with a steel core.
Why twisted pair of wires is used in instrumentation?
Because, from total 8 wires 4 wires are used for actual data transmission ( i e for bit transmission ) and remaining four wires are wounded to these wires to avoid crosstalk and radio frequency interference (RFI).
What was used to make airplanes before aluminium?
Wood and fabric were used before aluminium.Wood and fabric were used before aluminium.
