230 kV Wood Pole vs. Steel Pole
230 kV Wood Pole vs. Steel Pole
(OP)
We are performing a assessment to use wood pole vs, steel pole for a 230 kV transmission line in a wide territory in the Northern of USA.
Any advise or recommendation to use wood pole vs. steel mono pole or lattice structure?
Thanks

Also steel and a copper ground needs to be clamped with the right hardware to prevent galvantic action. Wood dosen't have this problem. Also the grounding of each, or every third, or whatever, should be consitered, in that a pole butt ground is possible with wood, but steel requires a driven ground.

Spun Concrete poles are also popular as an alternative to the lattice steel towers.

However, in the US, to makeup for the wood pole lower strength there are more structures per mile. But where there are taller trees, there are generally lower wind speeds.
Also pole treatment should be factored into the equasion, and pole life at the location it is installed. Same issue with steel, and footing size.

Our utility has occasionally [in the northern part of Ontario, Canada] had major issues with wood pole damage by pileated woodpeckers - and these birds give not one whit for the nominal voltage of the equipment being supported, provided they don't get so close to the conductors as to experience corona tickle
Wooden poles [as opposed to steel ones] provide an excellent gripping surface for birds , and often have a resonance characteristic that makes them peculiarly appealing as prime drumming objects for use in establishing and maintaining territorial boundaries - and unfortunately when a bird has decided precisely where the "sweet spot" is on a particular pole, it bangs away at it repeately...
Local topography and forest considerations, viz., tree species, their height, age, health, etc. have profound effects on whether or not ornithological damage to wood poles becomes problematic.
