Sad, but true... Even porcelain pintype insulators are fading from use. Here is a photograph of modern day power distribution in Napoleon, Ohio. The main wires don't even need insulators at all, just aerial spacers (generally of plastic) to keep the wires apart.
Even the one porcelain dead end insulator in use, on the horizontal wire running off to the right, is attached to the pole with a fiberglass rod.
Soon, even arrangements like this will be a thing of the past. They will probably be
replaced with underground wires that we will never see...
