- 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

- 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
