Not to long ago I bought a book called
Infrastructure: A Field Guide to the Industrial Landscape by Brian Hayes. It's a really cool book covering all of the man-made "stuff" that makes modern living possible. There are a large number of incredible photos with full explanation of things like elements of the electric grid, water towers, blast furnaces, telecommunications pedestals, and everything in between. The book does a wonderful job of explaining complex infrastructure to the layman, giving the reader a glimpse of the engineering feats that people take for granted everyday.
From my own "infrastructure" photo collection: here's a different view of a 138 kV transmission tower near Findlay, OH. If you look closely you can see the equipment monitoring the tension of the dead-end conductors on the left ("take off") side of the tower.
