This is a series lighting circuit regulator pole - have identified the various parts.

Thanks for the info David, you learn something new everyday. I hope my caption sounds better now, lol.

I've never seen so many various cans on one pole before!

Thanks IE_RICK for bringing everyone up to speed on what the parts and pieces are (were) on this pole. Sadly, I was through Bluffton a little over a week ago and all their series is gone. However there are still plenty of places this stuff exists... and in a few situations, it's located indoors (!) at central station substations for series lighting. Keep on reporting these things... I own a company that's dedicated to helping keep series lighting circuits in use well into the future!

Sad to hear that the rest of the series is gone. I was hoping to get back down there to photograph a few more poles, because the last time I was down there a lot of the series lighting was gone but still up a year earlier. At least they recycle some glass insulators (Although common) back into service use.
