What are they using as conductors? 1MW is 1202A @ 480V three-phase, 288.6A @ 2kV three-phase, and 115.4A @ 5kV three-phase. That’s a lot of power, at 480V you’

What are they using as conductors? 1MW is 1202A @ 480V three-phase, 288.6A @ 2kV three-phase, and 115.4A @ 5kV three-phase.
That’s a lot of power, at 480V you’d need (4) parallel sets of #350MCM. #350s weigh just over 1lb/ft.
Some kind of articulating busbar with some sort of specialized connector, perhaps?
- simne 2y agoIn news said, they use 1KV for ultrafast charge (400km in 5 minutes). Probably, three-phase. And you hit bull eye - as I know, ultrafast charger cable usually have liquid cooling.
- quickthrowman 2y agoGotcha, that makes sense. If there’s liquid cooling for the conductors you can pump a lot more amps through them than you can at 75C. If you can keep the ambient temp to 0-10C, you multiply the ampacity in the 75C column by 1.36, I bet you can go way lower if it’s liquid cooled.
