The wires have a direct path to the ground if they run next to or into a transformer. Because most transformers are made of metal, they can conduct electricity downwards, which power companies don’t want. As a result, insulators are used to separate the lines from the transformer’s edge.

Insulator disks in power plant transformers can also protect storms and electrical surges. You may have even witnessed power lines being struck by lightning and wondered what would happen. Thankfully, if there are insulators up there, you won’t have to worry about this.
