Jos, A man could put to in a container and pot them but heat don't escape that easily this way I don't think. Some say potting makes them cooler by making it like a heatsink. However, in calculating

Not to drift off the subject too much, but I've heard that some hams many years ago would drop there amp's HV transformers in a bucket of oil and run the heck out of them, much over there rated curre

ORIGINAL MESSAGE: ** REPLY SEPARATOR ** I'm sure this will increase the transformer's power rating some, but the problem is the oil can only remove heat from the outside of the unit, not from deep in

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

Wouldn't the insulation between windings eventually saturate with the oil thus allowing better heat transfer from deep inside? Larry N5BIP What they used to do on oil cooled transformers, is places s

ORIGINAL MESSAGE: ** REPLY SEPARATOR ** Good quality transformers are already impregnated with varnish, so the oil would not penetrate. The varnish does help to conduct heat out, but since it does no

The trouble with varnish is that it leaves air pockets inside the transformer because it's volume decreases as it dries, This is not the case with resins that use a hardener. Rich Measures, 805.386.3
