Yes, aluminium's tensile strength isn't high enough to suspend its own weight, so a steel-wire core is used.

Aluminium wire is used to make transmission cabels?
High voltage power distribution: The transmission and distribution of high voltage lines over long distances are done with the help of aluminum cable. Almost in all such transmission across the world aluminum is the dominant material.Electrical energy distribution: Aluminum cables and wires are widely used in motors, electric lights, power systems and in numerous appliances. Today it has become the most efficient and economical way of transferring electric power.Energy cables: Aluminum is a light weight metal and it weighs about one-third of copper. One kilogram of aluminum cable is able to carry twice as much electricity as one kilogram of copper. Therefore, aluminum power lines are lighter and require little support structures.
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.
Why you use aluminium in transmission lines?
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.
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.
Single most common metal in electrical transmission lines?
ACSR - Aluminum Cable Steel Reinforced
What is alluminium conductor steel reinforced in electricity?
Aluminium conductor is reinforced by steel because it can give the strenght required to support the weight of the cable without streching the aluminium, which is very ductile. It gives a specific type of high-capacity and high-strenght cable, typically used in overhead power lines.
What is A technology that uses cable TV lines for data transmission?
cable modem - A technologythat uses cable TV lines for data transmission
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 types of wire are used in transmission lines?
Stranded aluminium, with a steel core.
Why transmission lines are thicker than TV cable wires?
Transmission lines are thicker than TV cable wires because the transmission lines are used to transmit both low freq and high freq signals. And the losses of the transmission lines depend the resistance of the line which inturn depend upon length and area. As we have to transmitt the signals over long distances the transmission lines are thicker in size.Whereas in TV cable wires the construction is totally different in which transmission of signals is in between two conductors thereby avoiding losses.Therefore there is no necessity for these lines to be made thicker. That is why transmission lines are thicker than TV cable wires.
What is the sizes of cable for transmission lines?
336 776 and 795
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 is the purpose of ground wires in overhead transmission lines?
connection of the ground of all the transmission lines and used as a communication cable between protection devices
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.
A cable modem uses phone lines for transmission and is bundled with your local phone services?
