What is the arrangement of the LV overhead line, what is the designation of the

Hello
Cables the LV overhead line visible in the first photo in the attachment. As the reconstruction covers only part of the line, I have to replace the two pass-through stations with the end stations (see photo 2). I am asking my esteemed colleagues for help in determining what is the professional name of such a network system and what is the end crosspiece visible in the second photo. If someone has old catalogs with this type of line, I would like to learn more, unfortunately I cannot find anything about this type of LV overhead lines.
I can repay the owner of such a catalog with other catalogs with nN overhead lines, e.g. PTPIREE, both older and newer
greetings

You are seriously - you are replacing a piece of the LV network - I understand a power plant by order - and you do not know what it is or what it does not know, there is no project of these works, contract, material specification, cost estimate or something like that?

Seriously, these are lines built in the 70s in the archive, yes, we can find excerpts from the project where there is a change in the description: "LV line on prefabricated ZER-type poles with a flat arrangement of wires according to a typical solution" while in the assembly table a description of the structure end point PK through crosspiece PP
The designer says what catalog he used, i.e. the LN-100 catalog, but I do not have access to this type of catalog, and even if I had it, there would be no solutions for a spun pole in it. Nevertheless, I found an end spun pole with such an arrangement of lines, unfortunately I still don't know what type of construction it is. I cannot use the common end crossbar because the line in the photos has long spans up to 80m, which increases the spacing between the lines,

There was a similar topic here, ask the people discussing that topic.

I currently have two topics on my board to modernize lines made with such cables. Fortunately, I completely dismantle the antiquities, but I have to thicken the spans. As for the album, it's actually about the L-100. Unfortunately, among album and catalog "antiquities" I do not have this copy. In my opinion, there is no point in using some type of crosspiece, but it should be simply drawn using people from the power industry, maybe a surveyor who will measure the distances between insulators / wires. After determining these distances, you can use constructions e.g. for the PAS system.

Exactly. Since the investor commissions a task on unusual, archaic facilities, he probably should not do the grace and provide support. I suggested it in that thread.

By the way - why does the author assume an almost twin thread instead of continuing the other one? I am also curious how the fate of the 2016 task turned out.

the task from 2016 went so that the design used a corner cross member which has a larger distance between the first and second insulator, while the 3rd insulator was omitted, instead a strong structure was attached below the pole, but this is not a typical solution and I intended to do this in this project correct, but probably will not work, it would be good to at least know the spacing that should be between the lines so that something in the vat would draw.
Maybe someone will find in their archives the above-mentioned LN-100 directory ??????

Hello
I asked the wholesaler and received the answer that the end crosspiece for this system of lines for a spun pole is PKa3-100, unfortunately I did not receive any drawing
on the other hand, the stringers provided the PK-3/100 and KM-1 for the 4th line, also without drawings
Subject to be closed, but if someone had a directory for this type of lines, I would like to read it

I confirm the statement plum1978 S 80/2 insulators and AFL links
