Earthing of the F / UTP twisted pair - how and where?

Hello,
I know that the topic has been rolled over several times, but I have not found an answer that satisfies me. I have a LAN installation to do, 90% of the twisted pair will go next to 230V current cables, so the choice fell on the F / UTP twisted pair. I have a patchpanel and FTP sockets. The switch has sockets with a screen + ground on the back, the router has the same. At what points should I ground the twisted pair. Opinions differ, some say that at one point - on the patch panel. Others say that a patch panel and a socket, and others that a patch panel and a device connected to a shielded socket.

I have a grounding strip to which I can bring the grounding of the patchpanel.
Next to the RJ45 sockets there are 230V sockets (red with protection), the grounding of which is also connected to this earthing strip.

I am asking for advice.

You only have to ground in one place - preferably in a patchpanel cabinet.

Do you power any motors or other industrial equipment with these power cables?
If not, shielding may be more trouble than good.

from motors, it's just the gate actuators. The lighting (fluorescent lamps), computer equipment, printers, etc. are also supplied. The current cables and the twisted pair should be run next to each other, the twisted pair at 90% of its length is to go next to the current cable, and in some places it is to cross with it.

I would like to get 1GB / s on this

You buy an FTP patchpanel on which the twisted pair is grounded during assembly (metal bands included) and the patchpanel itself is grounded to the cabinet. From all philosophy.

It should be grounded on both sides. If you do only on a patch panel, it is ok. All the muck that will fly from other cables will be removed, but when it comes to protection against lightning, it is grounded on both sides

If there are no industrial machines with 20kW power consumption, only an ordinary office machine, I would do UTP.
If you are going to do this, it will be copper cables, not CCA. Better UTP copper than FTP CCA

Thank you for your answer. Case solved, we put the UTP. Maybe you have some proven installation cables? At the moment, drak and molex cabling looks interesting.

draka and molex.

I would add Madex.

Hello
Should the FTP twisted pair be grounded in only one place (e.g. patchpanel in a cabinet)? On the other hand (socket, plug) they can be unshielded, ungrounded (I cut the screen off)?

And what if the FTP twisted pair goes from cabinet A (grounded on the patchpanel) to cabinet B (or grounded here on the patchpanel)? This is to power another part of the building.

greetings

Since the socket is unshielded, you will not connect the screen there. You cut the screen flush with the insulation. Of course, such an installation is not art-compatible.

This is how you actually earn money in the FTP Pachpanel, which should be grounded together with the cabinet.

Do I ground at both ends (in both patch panels) or only in one place?
The twisted pair goes from the cabinet to the cabinet (powering another part of the building).
