Why don't utility companies use steal poles that much for distribution class when steal can last longer?

Answer 1

The downside to steel distribution poles include:

- More expensive
- Can't easily climb
- Reduced BIL level
- Field drilling for various equipment causes rust opportunties

Wood poles have a long proven track record in most of the US. It is not uncommon for wood poles to last more than 50 years. They are relatively inexpensive, are easy to climb and can be field modified for various types of equipment. Holes are routinely drilled in the pole for for equipment, conductor and guy wire attachment points.

Answer 2

Well STEEL is very expensive compared to the wooden ones that are available.

Steel conducts more electric than wood (Lightning Strikes Too), may oxidize and become dangerous, as pressure, weather treated wood is more resistant to the elements. Also some maintenance men climb the poles with steel, spiked boots, and you cannot plunge the spikes into metal.

Answer 3

it may because the steel will carry an electric charge while a wooden pole will not. plus with steel poles, they are more likely to be struck by lightning, especiallly if they are the only thing around. And wood is cheaper..

Answer 4

You obviously have not considered cost.
