Oil for welding transformer tank

[Ed_Dinning]

Hi Gents, in this application the oil is mainly used to remove heat; insulation properties are secondary. I am trying to avoid any problems with a mixture of oils. plus some heat and polymerisation may set in resulting in a jelly like mass. It could even be a problem with the residue left in the internals.

I'll get it opened up this weekend and see what volume I need (and what it looks like)
