Which is part of a transmission station bridging islands in NZ and probably one of my favorite pictures on the internet.
That's the scale of the hardware you're looking at... for a voltage 40 times lower.
It's also the picture I had in mind when thinking about 14MV. The size of everything to space out the stages would need to be so vast I don't even know if it would be structurally possible.
