Some sort of Insulating bracket?
|
I have seen these kind of brackets on wooden OR metal poles used in Denver- Xcel energy territory- A LOT.
What I have noticed is that when these brackets are used, there are LESS porcelain insulators, A LOT less, than usual.
Like on this picture, there would be 8 or 9 Disc insulators hanging down if it was directly connected to the wood or metal.
But on THESE kinds of brackets there always seems to be only FOUR hanging down.
I think these lines would be 115 to at least 150 KiloVolts, A standard voltage for High-Voltage Primary lines.
Are these Utility-Pole brackets insulating? They kind of look like it. I wonder what they are made of, some sort of polymer or something?
I posted this here cause all you experts might know about it. xD

And on this EXACT set there were some places with 9 disc insulators hanging down and the age was the same.
I am not sure... But it seems that this would be that high.
How many disc insulators hang down for a 115 KV system?
But you never actually know, maybe these ARE 115 KV but Xcel energy just made a dumb move. But I have seen lots of places in Xcel with these type of brackets.
What are the high-high voltage lines? I think I typically see like 20 Disc insulators on them, hanging down or dead end, they are probably different. Maybe more disc insulators I can't tell.
i've heard they have lines above 765 KV...i know there's some in Virginia..and 500 KV in California.
the benefit for raising the voltage is less current for a given amount of power transferred so you can use thinner conductors,though there's obvious risks too...who wants to live next to that.
Sometimes one setup has where one side of the lines has 345 KV and the other side has 115.
HERE Is an example.
The weird thing about that set of power lines is the POLES (or frames) Are meant to hold THREE sets of three wires, but only hold two, leaving one of the sections empty. What might be weirder is that instead of leaving the middle one empty they left one of the side ones empty.
For a while this set gets a third set of three, a 115 KV set that get's added on then branches back off to give electricity to the mountain areas, which actually give electricity to that 45 KV line that will be replaced that give electricity to my HOUSE.
You can see the same set HERE when it has three sets of three. But that was the only time it had three, you can browse the maps to see where they branch on then branch off.
Maybe Xcel energy had the money and decided to just spend the money using more expensive. xD
also..a Thread has began on this photo...High Voltage Ian Thread XD
They made brackets like what is on this picture in Polymer? These don't look polymer..
What do you think these brackets are made out of? They look like they insulate to me.
But they don't look metal, the metal part is on the edges where the insulators attach and where the bracket attaches to the pole, Which is why I think they are an insulating bracket.
