Delivered, at the beginning of April 2006, 3 transformers fill up with synthetic liquid MIDEL 7131 adapted to 2750/2x1375 kVA ONAN, sealed type for converters. They will supply the new Terror of Tower at Disneyland in Paris.
These transformators are ermetic, this means that atmosphere never get in contact
with the insulating fluid. In order to allow the insulating fluid to dilatate
with the temperature variations, on the top of the box is present an inert "gas-pillow".
The ermetic solution concurs a strong reduction of mantainance.
