Otter Tail Power - Rolette, ND

Otter Tail Power - Rolette, ND
Here's another OTP sub with an unit transformer - 69kV in, I THINK 12.5kV out (but it may have been 13.2kV back in the day).

This sub serves a pretty good-sized area - Rolette, Mylo, Perth, and I THINK Bisbee.

That is probably the biggest transformer I think I've seen in a wooden OTP sub like that.
