There are 400,999 wires in that tube at most. I heard one more wire would course the connection trouble, like 401k... I'll see myself out

Cables like this were used to transmit overseas information I generate. Information like "no, you look dumb". Amazing to so many electrons were disturbed by me.

Is it weird the first thing I thought of was an anatomical cross section of a penis ?
MrHappySmiles
That looks like a tree fiddy per distance item.
StellarJay77
Ironically it does cost ~$350 USD per foot.
MrHappySmiles
That’s surprising. I would have guessed $350 per inch and expected that to be low…

Which cable route?

TheWonderfulWorldOfDickButt
Don't eat it. Remember what happened to the last guy?
Beelsebooob
That would be the purpose of the metal rods all around the outside ;)
PwnageHobo
They're not so much rods as a steel wire armour wrap. But yes, they offer mechanical protection
DirtFisher
#1 my OCD is yelling at me because the small cables surrounding the outside have a few gaps 😬😬😬
DingDangPong
It probably expanded due to being cut open, the gaps are probably closed when the cable is whole.

Note that this is an underwater POWER cable, not an undersea data/telecommunications cable that would run between continents and would be mostly just a very small fiber optic bundle.
StellarJay77
The end point connections of cables like these also require data communications. So there's at least a handful of fiber cables in here to facilitate communications. It's just not its primary purpose. Much more efficient to lay one cable.
BDBottom
Still gotta sharkproof the cable so it'll be armored, plus power for the repeaters, so it'll be thicker than expected: https://en.wikipedia.org/wiki/Submarine_communications_cable#Modern_history
AllTheGoodOnesWereGone
The Wikipedia article says they're about 1" in diameter.
theDutchhaveinvadedSwitzerland
Anybody know what is in there besides electricity? Like, what are all the other inner cables for?
wadenelson
There's gotta be some fiber optic in some of those.
ESChapin
Communication likely
PerthAussieMike
Seems to be quite a bit of wasted internal space there
bolobass
Possibly the difference between slight flex and just solid pipe.
Illendor
That insulation is there to reduce interference. Very smart people spent a lot of time thinking about how to optimize that cable.
pumly
A) The white areas are required for the electromagnetic properties you have them in all signal cables. B) the small air gaps are due to round cables, essential for flex - even the large copper cores are not solid but many small cores for this reason. C) there is plenty of space in the sea! So ‘saving’ internal space to make the whole thing thinner doesn’t give much advantage.
PerthAussieMike
Thank you for the explanation
PanNonOpticon
There is no air gaps. Anything that isn't cable is probably vaseline or something similar. It¨s much easier to fill the space with liquid than to make a cable that can handle the crushing pressure.
pumly
Sorry yes. The air gaps in the picture would be filled with a liquid I guess in a deployed cable.
PeanutPotPlant
But isn’t the reason for the copper cables being many small ones also to increase surface area for conductivity reasons?
pumly
You mean cross sectional area? A circle minimises surface area. The max cross sectional area would be one solid core. But that would not flex. Probably it would fracture.
PeanutPotPlant
No I mean outside surface, basically around the circumference. So that many small circles have a lot more surface than one big one. I think we learned that a conductor always has an electric field E=0 inside, so the charge only flows on the outside (theoretically)
derzoomer
I wonder whats the raw costs per metre of this cable
Huffermingle
Atleast $2 a metre
hockey4mal8
I know a meth head that can tell you exactly how much Sudafed you could get for that.

At least $3.

I use rule of thumb that 1mm^2 can carry 10A. So assuming 5cm diameter, that's about 2000mm^2, so 20kA. That's max, so roughly 10kA is safer. Taking the elsewhere mentioned 150kV, that would be 1.5GW. Loads of assumprions and rough calculations. And not sure why 3 cables unless the 4th conductor is the shield, then it might theoretically be even more (although safetymargins would probably also be larger than what I used).

This isn't a data cable. "Seestromkabel" is German for a power line in the sea
StellarJay77
Yes, but it's not just power. The connection points of these cables generally need communication as well so this cable contains what looks like at least a few fiber lines and some copper pairs backups as well as its just more efficient to lay one cable.
LastWishTonight
This is described as a 150kV electric submarine cable by Wikipedia , not for Internet data or anything
umibozusan
I can see two fiber cables in there too. At noon and 5
Leonon
Probably has internet too since anything using that much power tends to need a data connection and it's easier to just lay one cable.

electric and data crossfeed, you have to keep them separated

Ohh ohh ohh!
Gotta keep ‘em separated!
nailpounder
but maybe there's enough separation, I dunno.
