Single-Circuit H-Frame Poles and Lattice Towers

I have up a drawing of single-circuit wooden H-frame towers, or double-poles, and in one case a wooden tri-pole tower mixed with single-circuit lattice towers and what I call the "horizontal lattice towers," at least until I know what they're really called.

Like in my previous deviation submission just before this one, , I have wooden H-frame double-pole towers sharing power lines with the horizontal lattice towers, and again, this is what I mean by them: www.elp.com/content/dam/elp/on…

If you're interested, these are some other examples of the "horizontal lattice towers"

Okay, this just in: one way if not the only way to refer to these towers is Y-shaped lattice towers, or better, Y-type lattice towers and I think that's what I'm going to call them now, not "horizontal lattice towers." "Y-type lattice tower" makes a lot more since. (I just learned that thanks to the last URL before this paragraph.)


Originally I was only going to do one row of power lines but I decided to do two rows, which is almost equivalent to one row of double-circuit power lines.

So, now that I know what these lattice towers are called, and as I mentioned in my previous deviation submission, thanks to a trip I took through Oklahoma City, I learned that H-frame wooden poles can be associated with and share power lines with Y-type lattice towers. I mean I might have known that before 1999, I just never thought of such a thing until I saw it, and so began my mentally associating wooden H-frames with Y-type lattice towers.

Getting back to the towers in this picture, I did two rows of power lines to show one difference. Now the towers on the left side are bigger than the towers on the right side, and the bigger ones have a slightly higher voltage than the smaller ones if not the same amount. The left towers also have more lattice towers than the ones on the right. On the smaller poles, I decided to make a triple-pole tower, which is very common with wooden H-frame double poles. In fact these are some examples of the triple-pole towers:

Not enough proof these poles are associated with the H-frame poles, I'll list some street-view examples
Highway 90 near Sierra Vista, Arizona

(Better example, same highway but further south and east) www.google.com/maps/@31.572123…

Anklam Road, Tucson, Arizona (Note: You may want to zoom in to see clearer)
www.google.com/maps/@32.225756…
(Same area but with a more about-face direction) www.google.com/maps/@32.225756…
Another note, this is not too far from Pima College West Campus)

Interstate 19 South of Tucson www.google.com/maps/@32.125706…

But I put it next to a Y-shaped lattice tower, and did this to show that where I put the tri-pole, I could have easily put a Y-shaped tower or some other tower there and where I put the Y-lattice tower, I could have easily put in another tri-pole tower or something else. So I made one little difference and made everything else the same.

These are a couple of street-view examples of Y-type lattice towers sharing power lines with H-frame poles:

On Irvington and Pantano in Tucson (near Pima College East Campus)
www.google.com/maps/@32.162943… Okay once upon a time there were wooden H-frame poles in this area but now there are steel mono-poles. Let's try something else.

I19 South of Tucson (zoom in as far as you can go) www.google.com/maps/@32.119568…

Nogales Highway Summit, Arizona (south of Tucson)
www.google.com/maps/@32.008828…
www.google.com/maps/@32.003960…
www.google.com/maps/@32.000954… Yes there's a railroad crossing in this area but that's not the main focus of this picture, the H-frame poles and the Y-type Lattice tower is.

One last example I'll give is on I10 northwest of Tucson

The bottom line is I find it interesting to see H-frame wood poles associated with Y-type lattice towers. It's also nice to see H-frame poles and Y-type lattice towers associated with other types of poles and towers. And again, thanks for my trip through Oklahoma City, I learned H-frame wood poles can share power lines with Y-type lattice towers. And I saw more examples of it in May 2000 on my first trip to Phoenix several months after my trip through Oklahoma City.

Also for to see.
