Running a 40m Network Cable Outdoors: Double Insulation vs Shielded Cable

I need to run a network cable between two computers (about 40m), but about 20m will be outside the building, exposed to weather conditions, and about 10m will have to go horizontally between the buildings (the rest is on the roof).
The question is: Can I use a cable that has double insulation (supposedly special for outdoor use), but unfortunately it does not have a shield, or decide on a cable with a shield (more resistant to interference), but not adapted to outdoor conditions - because It's the only choice I have in the local stores.
Does anyone have any experience in this field?
Is it also advisable to use a rope on which it would hang between buildings, or maybe the cable itself is so durable that it is not needed?

I suggest using a cable suitable for outdoor use. In addition, it will be useful to use netprotectors on both sides - so that the devices do not crash.

A stranded wire is indicated unless the cable has a built-in (which is often found in cables for outdoor applications.

what do you mean by "netprotectors", what are the prices?
for now, until I save up for some inexpensive radio and switch, it will have to run net (I have Wlan) with the 1st computer connected. I have a hub (NetEasy by D-Link, 10Base T Ethernet Hub-model DRH-5TC ver. A3) and I have to buy a Lan card (probably Planet with "wake on lan") for the 1st computer because the 2nd one is on the disc.

Hello

read here: https://www.elektroda.pl/rtvforum/topic250282.html

you need to use a cable for the cable (steel wire is enough) you will screw the hook into the expansion bolt on both sides - it will be a reliable and durable solution

I see a lot of typical twisted-pair cables on blocks outside - the choice is yours
remember that the FTP shielded cable will not protect you against atmospheric discharges

I saw the installation outside the building and between them on a stretched steel cable - the whole thing is about 40-50 m, works flawlessly and the cable is ordinary (madex or something). I do not know how many years it will last, but unfortunately special cables with gel inside are much more expensive. I do not recommend leaving the cable under its own weight.

phew. I found a lot of this information on your links, especially from my friend kasprzyk. I think I know everything about hanging. Maybe someone knows something about security. what do you think about this security? http://www.dronet.pl/dronet/stechnika.php#burze if it's necessary

Added after 17 [minutes]:

do you have any experience regarding the overvoltage strength of LAN cards used for computers - it's about specific models (affordable price). Supposedly the old ones are better made. I have an old hub that I will probably use (NetEasy by D-Link, 10Base T Ethernet Hub-model DRH-5TC ver. A3). Does anyone have any data for it, does it have any security features, because I haven't found anything?

At my company, we put a twisted pair cable for a test outside at a distance of 170 meters (yes, yes, 170 meters) and the network was a bit lost at 100 Mbit, but after setting it to 10 Mbit, it has been working flawlessly for about 2 years.
