Is there any sort of guidance regarding cable calculations ambient air temperature in gases other that air? I am currently looking at a cable calculation that requires a few cables to be run in a sealed argon environment which has a worse heat dissipation than air so the cable would run less efficiently. If anyone has had any experience with this advice or literature on this would be greatly appreciated. What correction factors did you use or if you didn't bother with correction factors what was your argument / evidence to support this?
