Primary wires are on top of the pole and usually carry 12 000 volts of electricity from a substation.
Ceramic things on power poles.
It leaks if you don t seal it.
Electricity is like water.
Metal and concrete poles can last much longer but eventually all utility poles need to be replaced.
From the length of the insulators probably towards the higher end of that spectrum.
The distribution lines that run down your street are probably 5 15kv.
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.
I ve seen these stacked disc structures on high voltage power lines everywhere.
Insulators are those glass or porcelain things you see on the tops and crossarms of telephone poles.
Insulators prevent energized wires from coming in contact with each other or the utility pole.
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.
Ever notice that power lines don t actually touch the poles.
Cutouts act like a fuse and open when there is a problem with the line or a section of it.
I could not find any information regarding this particular shape though.
6 insulators protect electricity from draining into utility poles.
What s on an electric power pole.
Those are the insulators.
