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.

SECO is a distribution company, not a transmission company, so they may know. The govt ruled to prevent vertical integration of the industry. FP&L is the assumed generation company. However, the utility industry is classified as a CNI industry. Critical National Infrastructure and as such, certain physical properties are only on a need to know basis, even within the company.
