On the way to Piacenza, this morning (it's evening, now) I saw a pole, quite along the road, with some 30 and 20 kV insulators: I removed all the sane pieces. The aqua glass ones are MIVA M 320 CA for 20 kV, and the clear ones FIDENZA 6330 for 30 kV rating. The double 20/30 kV lines have been subsituted by new 15 kV lines in "Elicord" (cable that need no insulators). Here on my balcony just back home.
