Our DC Link cable between the Islands, here in New Zealand(500kV DC) uses Nitrogen gas to keep them cool, not sure what they do with the gas, once it comes out in Wellington,but it must be pretty hot, with all that power we are sending up there, to run all their Cappucino machines and Luxury apartments.
