Ceramic Things On Power Poles

Instead the electrical lines are attached to things that look like dinner plates or cups.

Ceramic things on power poles.

Those are the insulators. It lowers the voltage from the higher voltage in the supply lines to the power used in your house. I could not find any information regarding this particular shape though. From what i ve noticed high voltage ceramic insulators only insulate conductors end to end not inside to outside like traditional plastic insulators.

It s a distribution transformer aka pole pig. It leaks if you don t seal it. From the length of the insulators probably towards the higher end of that spectrum. Cutouts act like a fuse and open when there is a problem with the line or a section of it.

Electricity is like water. The distribution lines that run down your street are probably 5 15kv. What s on an electric power pole. Metal and concrete poles can last much longer but eventually all utility poles need to be replaced.

I ve seen these stacked disc structures on high voltage power lines everywhere. Ever notice that power lines don t actually touch the poles. 6 insulators protect electricity from draining into utility poles. Their purpose is to insulate the electrical wires they carry so that electricity or telephone calls don t all leak into the pole and into the earth.

You definitely don t want the power lines connecting to the poles.
