[Amps] RE : MW Oven Transformer question

[Will Matney]

What they used to do on oil cooled transformers, is places some thin wood strips between each layer making a small windown that the oil could seep though. Of course using oil on a regular transformer will only help to a small degree, I agree. If the oil can't make it to the mean turns of each winding, it's about useless except for keeping the core cooler.

Best,

Will
