Here is a new transformer pole from Danville Utilities. Note how they recycled the glass insulators on the neutral.

Also, interestingly, the transformer is hooked up to an oil circuit-breaker on the primary.

Protection against the primary slapping together or tree branches in the lines?

I'm not quite sure to be honest with you. I'm wondering if these cans could be used to power street lamps?

Did you also see the one with the old (and hard to find) 7.2kV "mushroom" style breaker on it?

Great find! :)

Is this for a lighting circuit? California has a lot of oil breakers controlling lighting circuits.

Could perhaps be. A lot of the munis did odd things like that to replace their old 6.6a series systems.

Definitely a lighting circuit. The photocell is located just to the left of the "25" label on the transformer. I can't say this is a totally common way to run lighting circuits... I'd say most of the country uses individual photocells... but for those that group switch, this is one way to do it. Probably more common way is to use contactors. There are lots of those around the Las Vegas area. They're pretty easy to spot - a smallish box with a photocell on top - mounted at the top of a pole somewhere along the run.
