IMHO; 500kV is not exceptional, but the 380m tower height is dictated by the width of the span they want to cross, the droop of the catenary and the strength of the power cables. Then, the wind forces on those cables mean the tower must be strong as well as high. Congratulations to the designers and builders of this truly astounding project.
What is the highest capacity transmission line in the world? Seems we need to build them across all continents to share renewably powered electricity back and forth for our citizens...enabling a systemic phase out of fossil fuels and their carbon emissions, air pollution and energy insecurity.
@@aaronvallejo8220highest I know is 760kV but I might be wrong. There might be higher. The longer the distance compared against the amount of power that needs to be delivered, the higher the transmission voltage has to be in order to reduce losses.
Chinese is a ‘tonal’ language: meaning is carried in the pitch of the phrases. Interesting that these women also speak English pretty well. Can’t say as much for the average American, myself included.
So Amazing ! China is helping themselves and the world by building things like this ! Amazing workers also ! Very courageous ! And you should feel proud ! I thank you on behalf of my nation of Canada :) Be safe and have fun !
You don't want to climb up the longest spiral staircase in the world just to START whatever you're going to do up there? It makes me feel funny just to LOOK at it! For engineers this tower might be a kind of tourist attraction in itself! I would like to visit it, never seen anything like it.
As an american tradesman, I find these transmission towers to be modern marvels. The construction workers, architects, and engineers should be proud of themselves. That tower is a work of art. I even consider it to be a mega structure. 🔧 🏗️
If China need something they build it, no obstacle gets in their way, From bridges to railroad to buildings, hard work and dedication, and in Record times 👍👍 to China.
at this point there is likely no added tension because the heat cycling of the cables would cause premature failure from metal fatigue. just like a suspension bridge, they are just supporting the weight. high transmission loads through the cables likely causes them to droop by an extra 50+ meters so this stretching back and fowarth would not be good to add more forces like tension
That is going to carry a lot of power! So much "juice" over the wires! (Did he say 500 Kilowatts? That is not so much as it looks like it can carry much more!) Oh, I understand, it is tall to allow tall ships to travel beneath it!
Forget the Eiffel Tower, these things are as tall as the Empire State Building (minus the TV antenna). They are not the tallest any more however, another pair of recently completed towers crossing the Yangtze have beaten them by 5m!
It's a very impressive structure but I guess these towers will need a lot of maintenance over their life time. I wonder how it worked out cheaper to built these two towers that weigh over 7000 tonnes each than to lay undersea cable between he two islands?
High voltage line in transmission towers is the cheapest because the conductors are naked and unprotected. They are isolated by air and the heat is easily dissipate. At high voltage electrical cables can't be made large enough with wide enough separation because the cable needs protection and armour.
ya they can do underground cables but those are impossible to inspect and at these high voltages you need to pump in a bunch of oil insulator and so that can cause early failure if there is a leak in this fluid with any corrosion or crack. in california some of the underground high voltage dc lines have failed after their frequent earthquakes because they develop a crack and leak their oil out over time. it is then extremely difficult to fix this crack underground and takes a long time to basically place an entirely new underground transmission line. ur question is a good one though. one problem is the heat from high transmission can cause the lines to droop more than what you expect and the steel masts of ships plus salty sea water in the air makes for a perfect point of arcing to the ground/boats underneath.
Mate!! He mentioned this Pylon weighs 7.000 tonnes. In New Zeland 80 tonnes is a huge Pylon. The need for this huge structure I see a couple or reasons. To continue to carry huge voltage (500, 000) across a massively big span you need height and size.

Always we use Electric wire on the transmission tower,not the Electric cable.🎓🎓🎓🎓🎓🎓🎓🎓🎓⚡⚡⚡⚡🌏🌎🌍🌐😊

@@aaronvallejo8220there are two new powerpylons, 385 meters tall
If I had to work there I'd buy a parachute
Absolute beast.
The New Eiffel Tower! And it's doing a job, too! Not just something to look at. Watching those people working at height is making me a little dizzy.
There are two ON the jangtse river build in 2004 with 346 meters tall pylons and new ones with 385 meters
This announcer’s sing-song narration is too funny.

It appears very well braced. Looks like it is a combination of carbon & galvanized steel, stainless, and aluminum in the tower.
WOW... Congratulations for a job well done! All the best from Newfoundland Canada
Outstanding

Yeah especially want to thank them for covid 👍🏾
@@Tangaroa775 lmao you still think Covid came from China? Haha lmao
@@Phuong_Nguyen_ well it didn’t come from your ass💩
amazing
Amazing great build
I be no good at this...I haven't the head for heights

Honest!!!!
so beatiful wow!!
Very brave and fearless workers
Amazing!
Amazing, engineering and design!

those women got bigger stones than most men
A great feat of engineering
Imagine how much tension is on the cables

Happy to see such an amazing project in my hometown！But how the host said its actually not dangerous, need to hang him on the top of the tower😂😂
Check out "Night Scape" on YT if you think this is scary
That is going to carry a lot of power!
So much "juice" over the wires!
(Did he say 500 Kilowatts? That is not so much as it looks like it can carry much more!)
Oh, I understand, it is tall to allow tall ships to travel beneath it!
Not 500 kilowatts, 500 kilovolts :)
YEAH MOTHERFUCKING TALL SHIPS ARE SOOO STUPID TALL!
@@dimmon93 still not much for that heig5
i did see a vid once about a mega volt line that was needed to cover some 1000 od kms volts travel so high voltage to go long places.
WOW , THEIR ENGLISH IS VERY GOOD 👍
Makes me nervous watching that guy work on those insulators
Pay tribute to the builders of the great motherland! You are the best!
Forget the Eiffel Tower, these things are as tall as the Empire State Building (minus the TV antenna). They are not the tallest any more however, another pair of recently completed towers crossing the Yangtze have beaten them by 5m!
I am just worried that if by mistake the staff turns that on😨
How big are the stubs
The Bigger the Carbon FootPrint the Better!💯👍
In my city one tower is like this which can be seem from 10 km
It's a very impressive structure but I guess these towers will need a lot of maintenance over their life time. I wonder how it worked out cheaper to built these two towers that weigh over 7000 tonnes each than to lay undersea cable between he two islands?
look at the size of those insulators it would need a tunnel 20 mtrs for each cable there are 3 needed for each line. go buy a shovel see you later

Don't forget bro this pylon stands 52 meters higher than the sky tower lmao. Damm China beat us with a power line 😂
@@johnkepa2240
And they also built a great wall.
And they also built a mega dam.
And the world’s largest high speed railway system
China does up to 1,100kv in DC too. The back bone of Chinese transmission system is by Ultra HIgh Voltage which starts at 800kv.

Hey EUROPE, hey USAmerica ... WE are LAUGHING about you.... cheers from CHINA!!!!!!!!!!!!!!
"city par tar may I take a orer preez?"
THAT TOWER IS TALLER THAN THE IPLE TOWER AND TALLER THAN SIREN HEAD!
Great!
Nice
Amazing ,
Benjamin Franklin, would S#!T his pants, if he was able to see the progress of electrical engineering today.
you could just build 4 towers instead of 2. Two in de river with concrete protection. It would be half the height.
This is Great a big congratulations to your company.please help my husband please
Excelente
Mind blowing
We can call this Tower sky. Arrow
I hear it did topple over the following day
What if you made high up Energy Stations?
tbh china is having way to much fun with this
Could this be Superfly requiem???
Yes it is
im getting vertigo just watching
Where are the women ?
"Power tower"
Thats probably like one thousand kilovolts. 👍👍👍
telsa would be disgusted and disappointed
Someone is compensating.
How much size does it need? Yes! :Đ
shame not much building just people clambering and tying and untying their lines good vid for safety at height.
Wow
The news guy doesnt know that the name of the tower lol power tower
this is cringe worthy.
YYYEEESSS IIITTT IIISSS!!!
I wonder how long before it's a rusting hulk. Hopefully china I making all their bridges and train infrastructure low maintenance.
