Close?

Here in Colorado the Power Co. keeps everything on a 2yr. cycle for their Transmission Lines.We don`t run across very many bad burner`s that often.The only problem`s we run into is some home/property owners don`t really agree with the easement`s that the power co. has.
 
In Az we still have trouble convincing the USFS that right-of ways should be maintained, thankfuly we have had no fires caused by the trees brushing close the high voltage and transmission lines that we have crossing those valuable national forests. We also run into trouble with customers that don't agree with the easement when it comes to pruning and removing, but when the tree is on the ground or the want the wood removed, they usually claim that they do not own the property, all of a sudden it belongs to the utility.
 
More close shots

here's some pics of a couple spans that were skipped. This is a single phase, 7.2 kv copper conductor. This shot is looking down a tap that has burned a tunnel through the canopies of trees that were growing right under the line.
The "tunnel" is the hole in the canopy just to the right of the bolt on the pole, in the center of the picture. You can just see the grey insulator peeking out from behind the top of the pole, the span goes straight into the foliage.

Re: More close shots

here's a close-up of the pole. this has been neglected for some time, obviously. i could easily fit my whole arm inside..

Re: More close shots

another shot, this is where the wires exit through the trees, and continue to the pole & transformer.

Re: More close shots

here is a picture after removing everything under the neutral and exposing the primary and neutral so i could work the rest of the tree. It doesnt really show, but there was black, charred material everywhere.

Re: More close shots

ok, this is after removing most of the brush and the tops of the trees that were directly underneath. I still need to side-trim the spruces that are being spared

Re: More close shots

Are you working with that de-energized?
That conductor looks like it would break if you looked at it wrong. /forum/images/graemlins/grin.gif
 
Re: More close shots

No, the line is hot. I looked at getting a kill on it, but decided it wasn't necessary. the wire had burned back the tips and made it's own tunnel, so nothing was in direct contact. I've worked with burners before, and this wasn't very complicated, just tedious. The weather was dry and calm, and I was working out of a bucket, and I could put the truck in an ideal spot. i hear you on breaking that conductor...it had about 4 splices on it!
 
Re: More close shots

Man I know how you feel,I have been doing a couple of circuit`s that have been put off by the other contractor out here. Kind of pissed off that they were picking and chosing the line`s that they would do.That`s the kind of crap that give`s all us Line Clearance guy`s bad names.The public see`s that and they think that all of us are butcher`s.All I can do is take it with a smile on my face and say call the power co. Take it slow and easy
 
Re: More close shots

Kevin, we didn't get the lines rubbered up, but the bucket is dielectrically insulated. I am a journeyman Line Clearance trimmer, too, and worked doing exclusively line clearance for a few years. It was close, but pretty straightforward. The scenario I dislike is climbing big overhangs that have been let go, especially over three-phase, or transmission lines placed vertically on the pole with distribution on cross-arms underneath. At least these trees were vigorous, healthy, and the bucket makes it much simpler in a lot of cases, I think.

Treeblitzer, the reason those spans were skipped is because they were on federally owned property. the feds purchased the land, the poles, the wires, transformers, buildings, everything. the local electrical provider would trim as necessary for severe burners and outages, but these lines didn't even show up on their trim-cycle maps.

As you can see from those pics, i removed the trees that were right under the wire, and side trimmed the spruces up to specs. i think thats the best way to do it, those side trims on established conifers hold well, the tree can recover and heal those cuts, and you get minimal re-growth, so it's better for the tree and the utility. In urban areas here, they want you to leave the branches under the neutral, and tip back the branches adjacent to the conductor, to minimize the visual impact. The downside is that you then have a shelf of branches that tries to grow up-ward into the conductor, and you end up with a big mess of stubs and incorrect pruning cuts that is harder to maintain and will never look right. i've gotten hollered at for taking too much material, but i'm dead set against "tipping back" conifers.
