Here is some info on utility pole

More info. http://en.wikipedia.org/wiki/Utility_pole

Your typical utility pole will stand from 24' to 40' depending on the area. Some times you will see utility pole shorter(down to 8 ) or higher( up to 50'+) but not that common. Most range from 30'- 40'.

A utility pole can usually be divided up to four parts.

The first section is from the ground to the first light or wires.

The second section is fore low power wires like telephone, cable fiber optics and light.

The third section or secondary feed is for medium power. This is your local power distribution (the power is usually under 600V but this may very depending where you live) .

If it has it there is a forth section that has high power lines( the power in here is in the range of 1000V and usually is a feeder to a substation). The big towers that goes across country usually transmits at 6000V.

The first section you will find posters signs and other crap people have tacked on the pole. Some times you will find traffic lights municipal signs and other equipment. But in most cases they are bare.

The second section you will find telephone lines, cable, fiber optics and light.

Lights may also be mounted above or in the third section. If this was a wood pole there would be a small fuse box for the light. But a steel or aluminum pole can have the fuse box mounted inside at the base if there is room.

The third section is the medium power section. This is the most common part you see on a utility pole. It will have three wires for the three phases.

There is no four wires.

If you see four wires one of the wires is a support cable or it maybe a sets of two feed wires. And if you follow the line it will split in to two directions to service two streets or buildings

You may also see them with only two wires for the power this is for a street where the power line will end. Residential only needs two of these wires Some commercial and industrial need all three phases.

The loops you see under where the wires connect to the pole cross brace Are meant to keep the line from stretching when snow and ice builds up on the line.

If you look below the lines you will see a funny looking device. This is a fuse cut out. Some times they will look like a brown boxes. You will see them at all the transformers and where a line branches of the main line.

Next you may see “power” transformers (not the robots from the movies). These transformers come in many shapes and sizes. The most common is the can type then there is the can type with cooling fins and box types.

The forth section is at the top and only there if a set of high power lines need to go from the main substation to a local substation.

Some more notes
utility companies usually do not remove un-used lines from the poles. Like telephone and telegraph line do to cost. Also utility poles are assembled on site and has stuff added over the years. That is why there is no atypical utility pole. And why some time it can look like utter chaos.

I hope this helps.
