Ceramic Things On Power Poles

Primary wires are on top of the pole and usually carry 12 000 volts of electricity from a substation.

Ceramic things on power poles. You definitely don t want the power lines connecting to the poles. I ve seen these stacked disc structures on high voltage power lines everywhere. From what i ve noticed high voltage ceramic insulators only insulate conductors end to end not inside to outside like traditional plastic insulators. From the length of the insulators probably towards the higher end of that spectrum.

Insulators are those glass or porcelain things you see on the tops and crossarms of telephone poles. The distribution lines that run down your street are probably 5 15kv. What s on an electric power pole. 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. Electricity is like water. It s a distribution transformer aka pole pig. 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.

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. Ever notice that power lines don t actually touch the poles. 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.
