Oil Directed Air Forced Cooling- (ODAF)

Oil Directed Air Forced Cooling is an updated version of Oil Forced Air Forced Cooling (OFAF).  IN ODAF, the oil is directed through special channels in the core and close to the windings.  This makes the cooling more effective.  The hot oil is then passed through the fins which are cooled by fans. 

Oil Directed Air Forced Cooling is used in transformers with large capacities.
