Max,

Maybe "potted" is the wrong word. Sorry.

The MOT's immersed in a kind of hot, clear varnish/resin. After the 
air is pumped out, the varnish fills all of the space between the 
turns and between the windings and the core. After removal of the 
MOT the varnish hardens. Therefore oil wouldn't provide any 
additional insulation.

How do you call this process which is indeed very similar to the 
treatment of rolled/horizontally stacked polycaps?
