Cat6 unshielded with mains power?

No.

Yes. But if you're putting in once Cat6 put in another if not three more. They can share the same conduit. As can the mains. Cable is cheap, installing it isn't.

Interference isn't the problem, CAT6 insulation isn't mains rated.

Thanks Dave, perfect answer.

They can only run in the same conduit if both cables are mains voltage rated, I've not seen any 230V cat5, but there is this

Beware that one type has a single data pair (no use for ethernet) and another type has four pairs.

And quite surprisingly, toolsatan sell it by the metre (no conduit required direct burial for the SWA version)

or if you've got a conduit already, there's the hi-tuff version, except they're out of stock

No, that was the single pair version, the cat5e hi-tuff is

Having more than one LAN and not wanting to use VPNs is cheap too.

If you're thinking just bung in one cable and pop a switch on the end yes that works, provided the single cable doesn't fail. Should it do so you don't have a "spare" to quickly change to.

Replacement brings you straight back to where you are now, installing from scratch. Do not expect to be able to pull a new cable through (or the old one out) of the conduit unless it is dead straight and you have access at any bends. You *might* be able to if you can find a proper cable pulling lubricant but I wouldn't like to bet on it.

Do you mean VLAN rather than VPN? But I'm not sure I recognise the use case?

I should imagine LANs (plural) over seperate cables rather than VPNs over a single cable.

I recently did some cable pulling, electric ring circuit, I used talc, it seemed to work, but I had meant to ask here if it was a good idea.

I take the point about failure, but will counter with the "you ain't going to need it" maxim. Cables are reliable. In the future cat 6 will probably be replaced by fibre or wifi. If I wanted to be future proof I would ensure the conduit could have new cable pulled though it.

Or even WLAN?

Yes, a VLAN is a work around when you only have one cable and want subnet separation (or whatever the proper term is for ensuring no route between the subnets).

Yes I mean VLAN and I can't afford switches that support it, let alone the time to configure them. It's not my use case, but a good one would be to isolate IoT members.

In which case, use a decent sized duct, maybe 70mm, swept bends and leave some nylon cord in it. I don't know what is in cable pulling lubricants but people say they make a big difference, Talc is very unpopular nowadays, as it is thought to have quite a lot of long term toxicity, but I suppose it wouldn't matter if both ends are sealed, as they should be.

Could be tricky in parts of Scotland if surface mounted.

Interesting that the weight is quoted as Kilograms per Kilometre. The voltage drop would be a bit excessive if your garden was that long !

You must be skint then:
