Oh, so this is what those balls on high voltage cables mean

Bigger than you think!

If you drive along a couple of power lines, or if you just look at them from the ground, these balls don’t look very big. You might think they’re about the size of a basketball. But nothing is farther from the truth! These balls are a lot bigger than you think. The reason we think they are so small is because there is quite a bit of distance between the ground and the cable. The larger variants have a diameter of about 91 centimeters.
