I did not know whether his transformer contained liquid, and neither did he.
If nobody else had happened by to clarify, he may well have opened up a
Pandora's box, so to speak. But, it doesn't matter at this point. Your only
reason for being here is because you needed to vent some anger that came
from somewhere else in your life.
I want to chime in.
I did know that the transformer was dry. Doug did not know that at the
time he made his post. I feel that his warning was warranted, even
though the facts that he did not know, obviated the need for his
I personally would prefer to be informed of dangers, even though some
of the warnings turn out to be irrelevant, as opposed to not being
warned of dangers that "might" be actual.
This discussion of PCBs has been very enlightening to me and I thank
both Doug amd "Me".
At what point in this thread did I claim to be an expert? Let's simplify:
1) OP says he has a transformer. His question contains clues which make
sense to people who know more than I do about transformers.
2) People who know more than I do have not yet joined the discussion, at the
moment when I posted my first comment. Matter of fact, mine was the first
response to his question.
3) I suggested he investigate further, which the OP (and a few observers)
thought was a fair suggestion.
4) A number of people decided it was a good day to hurl insults because that
somehow distracts them from their little, tiny pee-pees and their powerless
It wouldn't have mattered WHAT I thought. Based on my slim knowledge of
transformers, the information was enough enough for ME to know that his were
not dangerous. Why is it such a problem for YOU that I suggested he be
cautious for what.....4 hours until he knew a little more?
I thought PCB's were only used as a liquid insulating and cooling
substance, like for instance in the big cans up on the telephone poles
and substations. I imagine this thing does not involve any PCB'sdue to
the way he describes it as being in the open versus being submerged in
an oily liquid
Some others who have responded have indicated that the capacitors may
contain PCBs. I simply threw out the other possibility because it's worth
looking into, especially because knowledge costs nothing.
But the GUY who disassembled the transformers is okay, right?
Maybe there's PCBs. Maybe not. If there are PCBs, there might be enough to
be detectable. If so, diluted 1-trillion-to-one in a nearby pond might be
sufficient to give one fish a headache.
Bah! Who cares?
Why not offer the whole thing to a scrap-metal dealer? When they melt
it down they'll recover the different metals...
Yeah, remove any bolts, and start splitting the iron core segments
apart (they are probably alternating meshed E and I pieces). Once you
get the first few out the rest will come easier. I'd use an
appropriately sized screwdriver and hammer...
If you mean bury it? NO! It is insulated copper probably!
Polysol insulation will burn off, Polythermaleze will burn off with a lot of
heat, Formel insulation will probably not come off with any fire. These
coatings are usually made to withstand severe heat in use.
You could use it for a long wave antenae or how about a lightning collector
to power that 25W bulb for a few seconds with the $100K in equipment to
catch that once in a lifetime strike?...LOL
Wind a huge Tesla coil on your roof and show the neighbours your nuts! (or
drop your pants when they are looking)
Can't this tranformer be used by somebody to generate a second 120V from a
single phase 120V inverter? It sounds pretty beefy.
BTW: once you knock the wedge out of the coil form the laminations will be
easier to get out. This keeps them from buzzing until the varnish and other
impregnations go into it.
I spent a multitude of hours as a kid taking stuff apart, including
small transformers. (Dry types)
Transformers are one of the least fun things to tear into.
With the size of the copper wire you say it has, it must have a high-amp
output. Is it stepup or stepdown? If stepdown, it could possibly make a
great custom arc or spot welder, or an electroplating supply.
