Have you ever thought about the electricity you use every day? How does it come to you and how are entire cities powered? This question is a very good one indeed.
Electricity in cities is delivered through a series of large, high power transmission lines. These massive lines run at a high voltage. In order to protect people from them, they can be more than a hundred feet tall. But how are they made?
High voltage lines are made of massive metal towers that are firmly attached to the ground. They can be assembled in a variety of ways.
They can either be put together horizontally on the ground and lifted into place, assembled vertically and erected on-site using a crane, or assembled elsewhere and moved into place using helicopters as aerial cranes. Those are quite some options!
How do they decide how far the towers should be placed from one another? That all depends on the voltage they are carrying. Lower voltage towers need to be closer together while higher voltage ones need to be further apart.
How tall exactly do these towers get? How much do they cost to make? And what types of cables do they use? Find all this out and more in our video.
