What's the maximum current carrying capability for this standard 800 kV DC line?
- tim333 8y agoNot sure for a standard line but the record is "1100 kV voltage, a 3,000 km (1,900 mi) length and 12 GW of power". So presumably 11,000 amps or so for that one. I guess you can have as much current as you want by making the cable thicker. Being built in China here approx https://www.google.co.uk/maps/dir/Guquan,+Putuo,+Zhoushan,+China/Changji,+Xinjiang,+China/@35.5671375,86.7761415,4z/data=!3m1!4b1!4m14!4m13!1m5!1m1!1s0x35acc82a82491295:0x23206530d23f54c4!2m2!1d122.717989!2d30.171597!1m5!1m1!1s0x3808bc263d8d6ebb:0xd1e6114bc906d7d2!2m2!1d87.308224!2d44.011182!3e0 https://www.google.co.uk/maps/dir/Guquan,+Putuo,+Zhoushan,+C... It's quite an impressive looking thing (vid) https://www.youtube.com/watch?v=VZ2KfrP_R3s https://www.youtube.com/watch?v=VZ2KfrP_R3s
- DoctorOetker 8y agoso transporting 1 TW would be a hundred of those in parallel
- tim333 8y agoI guess something like that. Probably beefier pylons and more cable on them.
- DoctorOetker 8y agocould submarine power cables in the Medeterranian sea be thinner since the water keeps the cable cool?
- tim333 8y agoDunno - bit beyond me that one.
- xyzzyz 8y agoYeah, but the average EU power consumption today is 0.35 TW, so with only a hundred of those in parallel (more likely spread around the Europe) you could literally satisfy 100% of EU power demand, and still have plenty of spare capacity.
