There are balls on power lines. What are the meanings behind them?
In the country away from cities, you may see large red balls placed on electric wires.In places where there isn't much else around, these balls are usually found.They warn of the power lines.
The large red balls that sit on power lines in the middle of the country are meant to help airline pilots see the lines.In open country, the balls are often found on the power lines.Airports in cities don't often need markers because power lines are far away from the airports and pilots can see the runway and obstacles more easily.
The balls help guide the pilots as they land at a smaller airport.There are power lines that cross rivers, canyons or ravines.The poles are far apart and the power lines are hard to see.
In addition to being used for airports, the red balls are also used in other areas.Many hospitals offer helicopter transfer of patients.Since a hospital is not the same as an airport, the balls may be placed on power lines near the hospital to help guide the pilot.The balls can be used on lines in areas where emergency medical evacuates are common.
One of the most common colors used for warning balls is red.The color used is determined by the surrounding landscape.Many of the balls are red, white or orange.You can see a combination of white and one other color.The alternating colors draw attention to the wires and keep planes out of them.
