Why Do Power Lines Have Those Orange Balls?

Описание: You’ve seen them stretched across river valleys and highways—bright orange balls clipped onto high-voltage power lines.

They look almost decorative. Random. Unnecessary.

They are none of those things.

Those hollow plastic spheres are one of the most important aviation safety systems in modern infrastructure. They prevent helicopters and low-flying aircraft from colliding with nearly invisible transmission lines—accidents that are almost never survivable.

In this video, we break down why power lines have orange balls, how they’re installed on live energized wires, why the color is carefully chosen, and how one plastic sphere can prevent million-dollar disasters.

You’ll learn:
🟠 Why transmission lines are nearly invisible from the air
🚁 How helicopter wire strikes happen
⚡ How crews install marker balls without cutting power
📏 Why spacing is calculated using FAA standards
🎨 Why some balls are orange, white, or yellow
💰 Why utilities spend millions marking transmission corridors

What looks like a simple plastic ball is actually a bridge between the electrical grid and the airspace above it.

Simple things. Simplified.
