Today I received this old photo taken by an ex ENEL lineman near l'Aquila town, probably in the '70s or '80s. The resolution is low, because was scanned from a small size photo, but it's possibile to recognize five porcelain insulators of the type called "Antrodoco". Only one was replaced by a glass type, probably a Fidenza 6330. This old MV pylon had also the smaller glass insulators of the service telephone line, but the wires were previously removed in the '60s. Now, these old lines were totally dismantled or renewed, and some old insulators were saved during the works.
