I need a 66 kV/40 MVA transformer for an indoor installation; what do you recommend ?

ABB's answer

Dry-type transformers are ideal for indoor applications because they safely eliminate the threat of fire and explosion. Normally available for distribution voltages only, ABB has developed dry-type technology for the 72.5 kV voltage class (HiDry). In combination with GIS or hybrid GIS switchgear, it enables installation of simple indoor substations in any building. There are also liquid-filled options available using natural ester fluids or silicon insulating fluids.
