    Hello, a family member wants to buy a plot of land where an overhead power line runs across the boundary. There are three wires. The poles with insulators are far from the plot, One of them can be seen on a google map. I am pasting below. What voltage runs on this line? On the geoportal the line is marked in red and there are two arrows. But I don't think it is a high voltage line. It looks more like medium voltage.
    A pole is where the line comes out of the ground and continues on air.
    What could be the minimum distance of a development from such a line? Looking at the neighbours it is about 6-8m.
    If it's a WN line this certainly disqualifies this plot.

    The distance of the buildings from the line in some places seems really small so why are the lines marked with two arrows on the map as if it was a WN line?

    .
    The marking on the map is an MV line and not a HV line.

    Hm according to this K1 manual the two arrows are WN and the dash arrow is SN.

    The line in the photo is SN

    Are there any contraindications to building / living under such wires? I am asking about interference with equipment in the house / noise / health of residents? Apart from that, is it not possible to erect a building in close proximity?

    If you write that you can't put a building in direct proximity, why do you ask if you can build under the line? That's just direct proximity!
    You can't, even because of the cost caused by having to shut down that line while building a house under it - health and safety requirements.

    Did you even read my post in concentration? I am asking about other contraindications besides not being able to build in the immediate vicinity of the wires. According to the neighbours, you can't build just 4m from the line.

    I don't see any contraindications apart from the prohibition.

Topic summary

The discussion revolves around identifying the voltage of an overhead power line running across a plot of land and the minimum distance required for construction from such a line. The user suspects the line is medium voltage (MV) based on its appearance on a geoportal map, which marks it with two arrows, typically indicating high voltage (WN). Responses clarify that the line is indeed medium voltage (MV) and not high voltage (WN). Concerns are raised about building near the line, with some participants noting that construction is prohibited in close proximity due to health and safety regulations. The minimum distance for building is debated, with some neighbors suggesting a distance of 4-8 meters from the line.
