What is purpose of the steel core in some large overhead conductor?

The wire you refer to is ACSR. Aluminium Conductor Steel Reinforced. The steel core is used to give the wire structural strength. When the conductor is spanned across great distances between poles or towers the total weight of the conductor between spans would be too much for just the aluminum wire to support. The steel center core is also known as the cables messenger.

Is a steel fence a conductor?
The steel used in the fence is a conductor of electricity.
Is steel a conductor or an insulator?
Yes Every metal is a conductor because of the free electrons (Except Silicon and Germanium; They are semi-metals) Yes, steel is a conductor
What material is the better conductor of heat cold stainless steel ceramic or plastic?
The better conductor is stainless steel.
Is aluminium better than steel to conduct electricity?
no, steel is not better conductor than aluminum due to structural differences between them.
Is steel the best conductor of electricity?
NO. Silver is the best conductor of electricity. (That is why it is used in satellites).
When is steel used as an electrical conductor?
the main purpose of steel in acsr conductors is for mechanical strength
What are the materials added in electrical overhead lines?
Overhead electrical lines are usually made of aluminum, and some have a steel strand added which is used to give the conductor more strength (not to carry current).
Is steel a conductor insulator?
Steel is a conductor.
Why is lead used in high voltage cables?
Steel-reinforced aluminium cables are used for overhead lines because aluminium is much lighter than a copper conductor, despite not being quite as good a conductor as copper. The function of the steel reinforcement is to improve the tensile strength of the conductor.
Is steel a good conductor or insulator?
Steel is a conductor and not an insulator.
Is a steel fence a conductor?
The steel used in the fence is a conductor of electricity.
Is stainless steel the best conductor?
Stainless steel is not the best conductor. The best conductor is actually aluminum.
Is steel a insulator or conductor?
conductor
Is insulator a conductor?
Steel is a conductor.
Is the element steel an electrical conductor?
Steel isn't an element but, yes, it is a conductor.
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.
Is steel spoon is conductor or insulator?
A steel spoon is an excellent conductor of heat.ANSWER: Conductor
