220V isn't very high in the power world. The US has 765 KV. I'm not sure what the highest voltage cable in the world is, but now I'm curious.

- ldiracdelta 9y agoIIRC, my college power professor said that Russian transmission lines carried 1 million volts, whereas US transmission lines only carry half a million volts.
- throwaway7645 9y agoWe do have plenty of 500 KV (all over Louisiana and Arkansas for example), but a good bit of 765 as well. It's very costly to get right-of-way and the bigger the installation the more right-of-way you need.
- mikro2nd 9y agoThere is a transmission system in India rated for something over a million volts. The last time I looked it was only carrying about 800kV, though. Just why this was so was not explained. IIRC it was on the Wikipedia article on transmission grids.
