From what i ve noticed high voltage ceramic insulators only insulate conductors end to end not inside to outside like traditional plastic insulators.
Ceramic things on power poles.
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.
It leaks if you don t seal it.
Electricity is like water.
Those are the insulators.
Primary wires are on top of the pole and usually carry 12 000 volts of electricity from a substation.
Instead the electrical lines are attached to things that look like dinner plates or cups.
You definitely don t want the power lines connecting to the 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.
The distribution lines that run down your street are probably 5 15kv.
From the length of the insulators probably towards the higher end of that spectrum.
Metal and concrete poles can last much longer but eventually all utility poles need to be replaced.
It s a distribution transformer aka pole pig.
Insulators prevent energized wires from coming in contact with each other or the utility pole.
6 insulators protect electricity from draining into utility poles.
What s on an electric power pole.
Ever notice that power lines don t actually touch the poles.
