Overhead lines generally use A.C.S.R. conductors.<\/p>\n
A.C.S.R. stands for Aluminum Conductor, Steel Reinforced. It is a type of conductor that is made up of an aluminum core that is surrounded by a layer of steel wires. This type of conductor is used in overhead lines because it is strong and lightweight. It is also resistant to corrosion, which makes it ideal for use in outdoor environments.<\/p>\n
Copper conductors are also used in overhead lines, but they are not as common as A.C.S.R. conductors. Copper conductors are more expensive than A.C.S.R. conductors, and they are not as strong. However, they are more conductive than A.C.S.R. conductors, which means that they can carry more current.<\/p>\n
All aluminium conductors are not used in overhead lines. This is because they are not as strong as A.C.S.R. conductors. They are also more susceptible to corrosion, which can lead to problems with the integrity of the line.<\/p>\n
None of these is not the correct answer.<\/p>\n","protected":false},"excerpt":{"rendered":"
