Evolution of electrical insulators [📹

Every subject should have things like this to help educate the world.

In Utah (near the Great Salt Lake) there's an amazing light show when a salt dust storm is followed by a snow storm. The salt forms a film on the insulators. When snow comes, it starts to melt which then creates a conducive path creating a huge Jacob's ladder like arc.

The first time I actually learned why they have those hats on electric poles. I used to think it was for aesthetic or rain-related reasons.

Ah, so THAT’S how those doodleybops on power poles work! 🤯

I had always thought why these insulators were shaped like this, thank you for sharing this 🙏🏽

A complex topic made clear with animation. Nice work!

I never knew.... thanks Massimo.
