> We use many gallons per year of Shell Diala X Transformer Oil.
Last year I had picked up a used Bird RF load and wanted to replace the
resistor core inside as it was slightly out of specs. As long as I was
doing this I wanted to replace the oil.... Bird only stocks replacement
transformer oil in 5 gal pails and it was sort of expensive. Eventually the
tech I dealt with at Bird sent me the material data sheets for the oil they
use.... Shell Diala X. I couldn't find a source locally that would sell me
any in under a 5 gal pail.....
I phoned the maintenance department of our local power provider and the
supervisor told me I could stop in a they'd provide me with some. I ended
up receiving 2 gallons pumped right from their bulk tank and they gave it to
me free. They said they purchase it by rail tanker and the time to process
my .20 of oil would cost way more then what the oil would cost.
Rebuilt the load and all is fine..... and I have quite a bit of x-former oil
to spare. I had asked about storage of the oil and they said just to keep
my containers sealed and it would store indefinitely.
I ended up getting a very nice tour of the shop and watched them rebuild
some large transformers..... pretty neat.
