Answer Posted / thilaknpti
dry transformers (containing no liquid) are enclosed in
sealed, pressurized tanks and cooled by nitrogen or sulfur
hexafluoride gas.
Experimental power transformers in the 2 MVA range have been
built with superconducting windings which eliminates the
copper losses, but not the core steel loss. These are cooled
by liquid nitrogen or helium.
