Why the High Voltage Power Cable Yes Ball-The ball?

Have you noticed stretch cord with orange balls are arranged in one stretch of the cord? Roughly to what was it, the balls are put in there? Let's find out ...

Actually, the balls are balls of markers to warn the pilot a plane or helicopter to avoid crashing into a stretch of power lines on SUTET. Electric wires stretched so thin it would look if viewed from space so the pilot is hard to see.

Well you must be wondering, why do not all the high-voltage electric cables have balls? The power cord has balls just wires stretching around the airport or a large place. Orange balls are mounted on top of the cable (cable lightning rod).

Hhmm ... why are colored orange huh? Orbs are usually given a very striking orange color, but they can also be colored to another depending on the environment. And even these spheres can be characterized by power lines due to the electric field of light, or it can be like a flashing light.

Still not wonder why most of the markers on the power cord is shaped ball? The answer is because the round shape is the best shape for air resistance. So if there is wind blowing from all directions, then it will not wobble too much experience.
