Wood Pole
Wood Pole
(OP)
Hi
What is the role of an electrical engineer in relation to specify wood or steel poles for distribution of power in as compared to a structural engineer.
I have a riser pole from a substation yard that will be taking one 750 MCM cable and then it will be a run of approx. 1 km at 13.8 KV.
I dont know, where to start and what should I ask the structural engineer. Could you advise me, where can I find some information about 15 KV wood poles.
Thanks

RE: Wood Pole
You could also try contacting your local utility to see if they have standards already created for that type of line design. If you can purchase an engineered standard from them, it might save you in the long run.

Ther is other good information on that page. http://www.usda.gov/rus/electric/bulletins.htm

RE: Wood Pole
It certainly wouldn't hurt to have a structural engineer review your work, but many design decisions like using 10% of pole plus 2' for embedment depth are empirical more than analytical. You may get flack from structural engineers who are not used to designing wood pole lines.
There may be considerations in some states if the drawings have to be sealed by a PE and your specialty is not structural.
RE: Wood Pole
There are tried-and-true methods for performing these calculations if you are outside of the standard configurations, and commercial software is available.
A long time ago I had a structural engineer look at some pole loading calcs and not being familiar with the industry methods, and without soil tests, he was not able to provide any useful feedback.
