Here is an even more ancient pole on a different former subtransmission line, which probably went up before 1925. This pole features Lapp insulators, which support heavy copper wires. I spotted corner poles on this line using Ohio Brass Baum Patent disks.

Here's an beauty: a Gulf Power corner pole with no fewer than twelve Ohio Brass Baum Patent disks! Also note the very heavy copper conductors. This is the oldest construction I have been able to find on Gulf Power, dating back to about 1920-25.

Another view of the ancient corner pole. There is no doubt in my mind that this line was originally subtransmission in the 15 kV range.

Here is an odd replacement pole on the ancient (former, now distribution) subtransmission line. The heavy copper wires are supported by sky yuk multiparts on a small steel arm. Looks quite weird compared to other construction!

The transmission line running overhead is 230 kV, with 12.47 kV distribution running beneath it. The 12.47 kV line was originally a 15 kV-class subtransmission line built in the early 1920s.

Here is an early replacement pole featuring different coloured multipart insulators.

Here is another original pole from the early 1920s, featuring one replacement insulator.

Eight (of eighteen) original Ohio Brass Baum Patent disks survive on this ancient corner pole.

This pole, which features a heavy crossarm, likely dates back to the 1950s. The insulators and pins were recycled from older poles.

Here's a vintage transformer pole (with a replaced transformer) featuring a braceless wooden arm holding a cutout and lightning arrester.

This type of construction, with the transformer under the secondary, has become very hard to find on Gulf Power. It used to be the standard for all construction until about 60 years ago.
