Ceramic Things On Power Poles

It leaks if you don t seal it.

Ceramic things on power poles.

Insulators prevent energized wires from coming in contact with each other or the utility pole. Instead the electrical lines are attached to things that look like dinner plates or cups. I could not find any information regarding this particular shape though. Primary wires are on top of the pole and usually carry 12 000 volts of electricity from a substation.

Insulators are those glass or porcelain things you see on the tops and crossarms of telephone poles. I ve seen these stacked disc structures on high voltage power lines everywhere. It s a distribution transformer aka pole pig. From the length of the insulators probably towards the higher end of that spectrum.

6 insulators protect electricity from draining into utility poles. Electricity is like water. Those are the insulators. 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. It lowers the voltage from the higher voltage in the supply lines to the power used in your house. The distribution lines that run down your street are probably 5 15kv. Metal and concrete poles can last much longer but eventually all utility poles need to be replaced.

Cutouts act like a fuse and open when there is a problem with the line or a section of it.
