Distance of buildings from the existing underground and overhead cable lines

Question

When I searched for information, I couldn't find a clear answer. The question comes up quite often. From what I found, in the PN-EN 50341-1:2013-03 standard, the distance of the building from existing overhead line with a voltage of 1kV

There aren't. And very well, I will only suggest that the cable can enter the building, pass through the building, transformer stations can be installed in the building. The designer, having knowledge about the planned investment, determines the risks and, in cooperation with the equipment operator, decides.

Maybe not the distance of the building, but the distance of locating workstations during construction works from overhead lines is specified in the REGULATION OF THE MINISTER OF INFRASTRUCTURE of February 6, 2003 on occupational health and safety during construction works, chapter 6. This basically limits the erection of buildings, unless the line may be shut down for the duration of the work.

I don't think we fully understood each other. Of course what you are saying is correct. However, if you are building, for example, a single-family house and there are overhead lines and/or underground cable lines running through your plot, you cannot pour the foundations on the cable. A minimum distance must be maintained. In the Regulation and the standard I mentioned earlier, there are some conditions in the case of collisions and close-ups.

Lots of information in the standards below. PN-E-05100-1:1998 - Overhead power lines - Design and construction - Alternating current lines with bare working conductors. PN-E-05125:1976 - Power and signal cable lines - Design and construction. N SEP-E-004 Power and signal cable lines Design and construction.

You can. Of course, in agreement with the owner of the cable and under the appropriate conditions. Imagine that you are building a terraced house or wave house, you put a pipe on the cable and put foundations, a lot of cables go under buildings, garages, etc.

You really have to be unevenly under the ceiling to agree to something like this as the owner of the cable or to put the building on the cable as the owner.
So far, I have not encountered such a curiosity either in Poland or, for example, in Ireland.
Cables were always laid so that they did not pass under the building.

It always makes me wonder how to treat it. Basically, these standards are about how to situate lines relative to existing buildings, not buildings relative to existing lines.

Such a situation: a friend was building a garage. He dug ditches for the foundations and found a thick cable in the corner. He looked at the maps, arrangements, attached to the building permit and did not find a cable. The closest one was 5 m away and ran a bit differently. found a cut steel pipe and built a garage. After the spring thaw, half of the district went out. ZE quickly found the reason under the foundation. They moved an active cable and issued an invoice for it. He took another loan from the bank. They reasoned as follows: whatever you find out about the shape of the cable, you are to notify the ZE. After negotiations, they gave him a few thousand.

@kkas12 I have exactly the same opinion, hence my questions. @spin As above - exactly! It is about a collision of a newly constructed building with existing lines. A friend, admittedly not an electrician, but from the construction industry, said that you SHOULD apply to ZE for an inter-industry arrangement. In this case, however, there may be a problem that ZE will require something excessive, as elsewhere colleagues have described on this forum, for example, the topic of grounding the PEN chapter and other inventions. In this case, it would be good to know the current regulations, if any. Unless here the main and only decision maker is ZE.

Distance of buildings from the existing underground and overhead cable lines

What minimum distance must a new building keep from existing underground and overhead power cable lines, and where is this regulated?
