Why are colored balls used in Power Transmission Lines?
Friends, today we will know why colored balls are put on the transmission lines, and what is their function. What are the use balls on transmission Power Lines?
Apart from this, this question is also asked a lot in electrical interviews. So we will know what you have to answer in the interview.
Colors of maker balls used on power transmission lines
First of all, we get to know what color this ball is to be seen on power transmission lines. So these color balls on power lines are of mainly 4 colors.
- Orange
- Red
- White
- Yellow
Weight of color maker balls used on power transmission lines
The weight of this one ball is about 5-7 kg. And the size as the diameter of this one ball is 36 inches which means as much as 3 feet.
This marker ball is made of plain plastic, but while making this ball, slightly harder means stronger plastic is chosen. So that the life of these balls is longer.
Now let us see where these balls are used. Which power line do we use the marker-colored balls?
You get to see this Colored ball on power transmission lines mainly in 3 places.
1) Hilly Area - This ball is mostly used on transmission lines used in hilly areas.
2) Long span – The meaning of long span is where there is more distance between two electrical poles. There we use the marker ball. The condition of the long span is mostly seen in a line crossing a river pond.
3) Near runway - The area around our airport from where airplanes take off and land. If there is a transmission line near that runway also, then definitely use these balls there.
What is the name of the colored balls used in power transmission lines?
By the way, we call it a marker ball in regular time. But its name is Aerial Marker Ball. Apart from this, it is also called a visibility marker ball.
Why Are Aerial Marker Balls Used in power transmission lines?
The main use of aerial marker ball is to prevent loss of life and property. This ball is used to make the transmission line easily visible to the aircraft flying in the air.
As we all know, helicopters cannot fly at high altitudes. So for these reasons, this aerial marker ball is placed in deep valleys, mountainous areas, and near airports.
Interview Questions
Q.1 What is the name of the balls used in power transmission lines?
Ans - The colored plastic balls hanging on the overhead wire are called Aerial marker balls.
2) Why are colorful balls used on power transmission lines?
Ans - With the help of these balls, electrical wires are easily visible to aircraft and helicopters, which are flying at low altitudes.
So, I hope you have got answers to many questions related to colored balls (Aerial Maker Balls) used in power transmission lines.
Thank You!
Have A Great Day!
Happy Learning!
