The lines going through Chitty Chatty are most likely 34.5KV, this line is the major feeder to all of the south end of Sumter County.

Within the United States, High-Voltage long distance lines are typically DC running anywhere from 100 kV to 800kV. It is not obvious as to the type of transmission used within Sumter County. The obversion that the large round ceramic insulators are 10 kV insulators is correct. So if you have 10 of these, it will be a 100 kV line; however, that doesn't determine if it's AC or DC. There are excellent reasons for DC in power transmission, you can read about them in wikipedia. If there are more than 4 ceramic insulators, the lines are unlikely to be 34.5 kV lines. Power line transmission is substantially different than local power distribution. The only way to really know the voltage of the lines would be to contact SECO, provided that the transmission lines going through the are even SECO lines. They would likely know the correct answer to the question regardless of the actual owner of the lines.
