Does anyone know the voltages carried by these lines?
and for the wise ones who will ask "why," I answer "just curious."

As a retired energy guy I can affirm that those transmission lines are AC. While a whole lesson in electric transmission is impossible on this forum, I’ll give you some info that should satisfy some of your curiosity. The whole Eastern Interconnect is AC with a little DC going to some isolated large use customers. We are part of the Eastern Interconnect. The US Eastern Interconnect goes from Canadian border to southern tip of Florida to the Rocky Mountains, but not into Texas. Texas has its own DC Transmission Interconnect. ERCOT. West of the Rockies is the Western Interconnect. The Canadian electric system has some DC that has special rectifiers where their system meets the Eastern Interconnect. The high voltage of the transmission lines throughout the Eastern Interconnect is all AC and the voltages vary from 138,000 volts (138 kv , 230 kv, 250kv, 345kv, 500 kv, and also some 765kv) 500kv has multiple strands for each phase, and 765 kv are monsters that you won’t see around here. You can distinguish higher voltages by observing the distance that lines are separated. The three lines that you see running parallel to each other are really one transmission line as each line has 3 phases. So if a tower has three lines hanging on it that tower is supporting one transmission line. If you see 6 lines then the tower is supporting two transmission lines. Check the size/ length of the insulator holding the lines and the longer set of insulators with tell you which line has the higher voltage. Ignore the small wire going across the top of the transmission tower as those are for lightning strikes. The voltage you’re asking about is probably 230kv, and 345kv.
