New electrical installation in the conduit and the possibility of replacing the

I have a question when replacing the electrical installation in an apartment in a block of flats, new copper cables should be inserted in the conduit, because thanks to this, at the next replacement, you only need to pull ??????

Yes, a few pennies per meter, and the walls do not need to be forged at the next replacement.

There is no need, coppers will easily survive several (teen?) generations. You will never have to replace them. By the way, I can't imagine pulling a cable in a conduit bent at an angle of, for example, 90 degrees ...
Regards.

And after how many years, on average, are such cables replaced?

I think it's 50-70 years old.

There are appropriate tools for this ... But a good solution is to put a wire / cord inside, etc. before laying the conduit. Then when pulling, just tie one end of the wire and pull the other end and it's ok.

What wires are you referring to? YDY? LgY? DY? OMY?

And when will this exchange take place? I guess the next generation will take care of that.
If the installation is properly made and operated, it will last a generation without overloading.
Even today, the Gierek aluminum found in apartment buildings sometimes holds up quite well, and yet there are more and more receivers.
The greatest degradation occurs at overloads and short circuits. Insulation also ages due to moisture. If these factors are avoided, the durability of the installation increases.

Buddy romky, if you can't imagine dragging a cable in a conduit bent at an angle of, for example, 90 degrees, imagine how they used to do the installations. Pipes or corrugated pipes were laid. The plasterers plastered only after plastering the wires and gave advice, but they were taught the profession from electricians and not on the forum, p.
Anyone who has replaced the installation where there were conduits or tubes in the house knows that this is a great help in later renovation, and it is not known what the fate of the apartment will be in the future.
How to do for yourself and you have time and conditions and the construction of the building allows it, you can give in conduits :)

If it's a block, you should notify the administration about it

Single DY wires are not pulled into the tubes, not multi-core ones.
3xDY will be more expensive than triple YDYp.
"At the next renovation, just pull new wires" - it makes no sense. Let someone show me the renovation of a 30-40-year-old installation, where only the wires were dragged - this is unrealistic. In old installations, there was one socket for the whole room, there were even rooms without sockets. Remont is a completely new installation with a completely different layout of outlets. In the old installation there is 10% of what will be in the new one and without tearing up the walls it will not happen.
And it will be the same with the next renovation.

Besides, if it is a block made of a large slab, I advise you to forget about conduits - you must not cut or forge channels in concrete. There may even be a problem with concealed fittings and you will have to use a surface-mounted one.

There was a small error here, probably a colleague meant something like this:

Everything else is OK, I agree.

Buddy michcio, you are partly right without tearing up the walls during the next renovation, but having conduits or tubes, it's easier to do the renovation because you don't have to tear down all the walls, only part of it ;p. I would show you such renovations of a 30-40-year-old installation where only the wires were pulled and the socket boxes were lowered without ripping the entire walls (only a part of about 30 cm), a clinker was made between the junction box at the top and the socket at the bottom, also without ripping the wall, using a conduit powering the socket ( obviously a clinker from another circuit) etc. :)

As for the great album, I completely agree with you, regards »

Only buddy, you will show the installations made in the 70s, when one fuse protected the whole house.

Arturo2005 you are partly right
You can debate for a long time about conduits, pulling wires and plaster under the plaster, and the author will do it as well as he can and will.

Only the number of circuits and the method of installation are two different issues.

Well, let's face it, we know exactly what the installation from the 70s looked like. Of course, exceptions (sporadic because sporadic) also happened.

But the topic is as follows New electrical installation in the conduit and the possibility of replacing the cables later and you should stick to it.

Just what to hold on to here, colleagues, what to debate.
It is obvious that if the installation is in pipes, it is usually possible to replace the wires (although not always and not in all places).
However, if there are no tubes, it is 100% impossible to replace the tubes without scratching.
Only now is the question.
Will we use this opportunity in the future?
I know from experience that it is average with this use, if it is a small alteration, sometimes something fits when a thorough change of interior arrangement is done from scratch.
The most important thing is not to incur unnecessary costs that make no sense.
If we decide on tubes, it is better to avoid conduits. On the other hand, the pipes must be laid carefully, gentle bends on longer sections, inspection boxes. The tubes themselves must be inserted into the boxes under the equipment. Installation in such a system is much more labor-intensive and more expensive in terms of labor and material, but only this way makes sense.
If they are to be only conduits placed for the eye and YDY in them, it is a pity to bother and a waste of money.

The conduit is only for signal cables, i.e. TV, SAT, LAN, telephone, etc.

And even for that it is not very suitable ... the corrugated walls of the conduit make it difficult to replace the cable, etc. Therefore, a PVC pipe is better ...

"That's what YDYp cables are for, to put them directly on the wall. It's not the era of conduit, where you had to pull in individual Dys and make furrows - by hand, because power tools were in the price and not everyone could afford"
"Someone pull a YDY or Dy wire 20 meters long with a few bends"

Dude cKKqa Think about what you write.

Go, for example, to Germany and see how they do installations in new houses in conduits, your jaw will drop; p

Years ago, they were made in various ways with plywood on the wall, also in Bergman tubes, conduits, etc., so today everyone can do as they wish and it suits them. The question is whether he will use these conduits later and who in a few years will live in the house / apartment and what finances he has. Ydyp lays on the wall because it comes out cheap and nowadays everyone is an economist, at least he thinks so.

Why in peszle? Not because it is easier to replace the wires later, because hardly anyone uses it (one of the previous speakers wrote about it). But because it's easier to make some other configuration. Don't have enough light switches? You are able to cut a hole in the wall (e.g. Suporex) with a hole saw and add another switch to the frame, and then you add another cable to the conduit. If it doesn't want to go in, I pull them all out and drag the episode over again.
I added switches with milled sockets and even the walls didn't need to be painted.

Of course, you can deliberately arrange pipes or conduit in such a way as to prove that nothing can be pulled into it.
But what does that have to do with professionally done work?

In countries such as Ireland, Great Britain and maybe Germany, other people (brigades) lay the pipes and others pull the wires.
So maybe a colleague of the cKKqa will try his hand in these countries and later boast about how long he worked as a "expert-professional" proving the impossibility of using what is successfully used.

What are you implying with your statement? That in 2-3 years a friend will pull the cord into a new socket, a new connector? Then it will not work without forging. Besides, I'm curious how he will do it in a boxless installation. For me, it's art for art's sake.

That's why I wrote that the installation in the pipes must be thought out and carefully made.
There must be inspection boxes on longer sections, and wherever possible, it is better to use tubes instead of conduits.
However, the argument of the possibility of replacing the installation without forging is more of a myth, it is rarely useful.
As for the furrows, it is rarely necessary to chisel them, the plasters are so thin that it is often impossible to hide even YDYp 3x1.5 without a furrow.

Buddy, you don't have much to say on this topic since you connect Gierek with bergmankami.
So, leave the assessment of the use of pipes in electrical installations to those who know something about it.

Forgive the comments at my address, because this is an old song of demagogues who have no knowledge of the subject..
Poland is not the center of the world.
And it will not be as long as people who have no idea what they are writing about will try to create reality or supposedly binding standards.

Today's technologies force forging grooves as well as more and more often suspended ceilings.
So it is enough to have a clear and open mind to use these two options to get out of the drawer.
you buddy cKKqa you don't want to get out of this drawer.

Of course the author will decide.
However, suggesting at the very beginning the "only right solution"

Quote:

Dude, put normal YDYp and don't play with conduits.

is not a discussion.

And recalling the proverb about language here is xenophobia and megalomania, my friend.
That means closing yourself to other solutions.
