Closeup of the porcelain disc-suspension insilators.
Here is one chain. AS you can see with 4 on a chain it's a bit wider than the M-400 R3.
This thing is HEAVY! And I have seen twelve of these on a single chain before, that would be twice as heavy! I wonder how those wires can support this weight!
Well this link was for sharp curves, obtuse angles more than 90 degrees. I already know that the voltage of the lines were 45 KV, and they had 5 insulators.
That wouldn't work because they put more insulators than what is needed sometimes depending on location, and envronment.
That's what I am guessing for this environment. The Power lines have 45 KVs of power, and when the wires dead end they use 5 of these disc insulators, and when they turn the wire in an obtuse angle, (More than 90 degrees) there are four of the discs, and if they are just suspending downwards on this set of 45 KV power, there are three discs. I wonder why they did that.
On our 115kv/69kv systems up here in western mass have 10 of these linked together, both dead ends and a strain supports on the poles. I'm not sure the rating of one disc but I sure can find out more by taking to the linemen around the company. Our 115kv systems are 69 kv phase to ground and I believe that's how they size the insulators but I could be wrong, I'll find out more info!
Hmm. I think they used about 10 or 12 on the ones in between aspen park and Denver, and they are probably 115 KV already, those power lines link to the 45 KV that go all the way to fairplay that they will be working on.
These insulators used to be a part of the 45 KV power-lines between Fairplay and Como, They finished the project (Section) last November.
Just a section of the 45 KV lines were removed, and it is planned for the whole 45 KV section of the power lines to be replaced and upgraded to a 115 KV system.
It's too bad because I have always known the power lines since I was a little kid, Even before I moved into my house in the mountains. At least I got to get some goodies from them and I might be able to get more!
Most of the 45 KV stretch is still up only a section was replaced, so far, but they plan to replace the entire string. If I don't move out soon because of the project I will end up having some power outages (small ones) Because those 45 KV lines give power to my house! They have been hit multiple times and every time they got hit or a wire broke the electricity turned off at my house for a while. xD

and i think he's right....the rating of one should be 1/4 of the whole stack.
