    Hello.
    The topic is actually quite known, but there is no precise definition of the problem anywhere.
    I will put a UTP network cable in the basement. There is a place where it would be most profitable for me to put a cable in a PVC strip with a 220V single-phase cable (max power consumption is about 2kW). This section is about 4 meters long, the rest is no longer close to the power industry ...
    Now I have questions for you:

    - if I put an unshielded UTP cable next to the power cable (4m section), there will be no interference causing loss of transmission?

    - if there is interference, can I put a shielded UTP cable in order to eliminate it?

    -if the answer to both of the above questions was: YES, does it make sense to have a shielded cable, if neither the computer nor the switch are grounded (the electrical installation is without grounding, and the computer is also ungrounded)?

    I would prefer not to check the phase effect on the network in practice, because I would not like to forge in the walls later, just in case ...

    Regards

    The biggest sin "of amateurs" is to connect these 2 types of wires.
    There will be interference and packets will be dropped and as a consequence the internet will be slower.
    In the switch and the computer, the ground potentials will be evened out and grounding would be useful ......

    There is no earth electrode, the installations were taken up by the power supply? :D Do you have a TT network?

    Thank you for the tutorial, in fact, there is an interesting description of something ...
    As for the installation, it is probably a 40-year-old installation, so there is no earth electrode. I don't know if there is a TT, but the RCD cannot be mounted, so I guess so. I am thinking about connecting the switch housing to the CO pipe and I am fully aware of the danger, but it just so happens that the switch will hang about 20 cm from the primary pipe ...

    Regards.

    I would bet more on TN - C because TT is a rarity (my sarcasm) and you must have a cordage (earth electrode) but you do not have a separate zero (working neutral) and grounding.
    CO pipes are aligned with the CC potential with PE (grounding) and the connection alone will do nothing to you :) In my opinion, change the cable route ;)
    Want another tutorial? :)

    Each guide will be useful :-)
    In general, I can change the route, but I have a section of one meter, where the cable would run approximately 15 centimeters from the phase cable, except that now the power cable would be in the wall. Could you like this?

    I don't give you much anyway :P
    I know I'm a pain in the ass but I've taught it through my life :)
    Will use FFTP CAT6A cables or at least FTP and terminals with "plates" Let something collect this network rubbish and give it to the mass :)

    Jeju ... He's buying an APeka and a WiFi card :-)
    Okay, the cable will run across the floor. Better? :-)
    The cable I have is CAT5E, so I don't think it's good for anything. Besides, I only have 7 meters of it ... And if you put the power cable in aluminum pipes fi = 8mm, electrically connected to the CO pipe, it will not do anything? :-)
    On the other hand, I already have one power cable located next to the phase one and plastered, and there are no major disturbances ...
    Okay, I'll try to run the cable on the ground, in a wooden slat. Ground the wooden strip? :-)
    Good for today, I'm going to sleep ...

    I know what UTP looks like a little bit of this wire was pulling :P If you want to have a reasonable speed, put it on the screen, no matter where :P

    Oh, I know you know what UTP looks like. I am rather amused by the signature "ELECTRIC CABLE" under this cable :-) . As for the topic, I will just try to avoid places close to electric wires, and where they will be, I will give a very strong screen, maybe even a steel pipe :-) .

    Thank you for your help.

    Remember that you have to ground this pipe somewhere :)

    I'll make something up :)

Topic summary

The discussion revolves around the installation of UTP network cables in proximity to a 220V single-phase power cable. The main concerns include potential interference affecting data transmission, the effectiveness of shielded UTP cables in mitigating such interference, and the implications of grounding in an ungrounded electrical installation. Participants emphasize that running unshielded UTP cables alongside power cables can lead to packet loss and slower internet speeds. Recommendations include using shielded cables (e.g., F/UTP or S/FTP) and avoiding close proximity to power lines. Grounding considerations are also highlighted, with suggestions to ground any metallic conduits used for cable protection.
