Have you ever considered understanding, why are U type jumpers provided in an overhead transmission line? What is the jumper line? What do you mean by it? Here, the conductor hanging in the U-shape on the transmission line above is the jumper line.
Now, what is the function of this cable?
Here, anticipation takes place about its work from it’s name. In fact, the jumper line means something will jump from one side to the other. Now the question arises, what is it?
Who is this power? Here, the usage of this jumper line is to carry electricity from one end of the pole to the other. As a result, there will be no direct electrical connection from one end of the pole to the other. So, they will meet with the help of this jumper. Now, let’s get back to the main discussion about why are U type jumpers provided in an overhead transmission line?
People on both sides of the river mingle using bridges.
The question is, where is the difficulty in a direct connection between the two ends? What can’t it be done?
Yes, it can be done. Why not? Just try doing it once. In the end, you don’t even have to touch the tower. Now, if you are 10 feet away from it, this tower will keep you hanging like a ghost. Why?
Because the body of the tower is a metal body. So, direct contact without the connection with the jumper line or insulator will short circuit its body. Now, in the end, this will create a very strong magnetic field in its vicinity.
