I am demolishing a huge 8 kVa UPS. Lots of nice wires, screws etc.

It has a large transformer, it weighs around 200 lbs. It comes from a
that 8 KVA Ferrups UPS. There is a super heavy square shaped copper
wire on it, which, I fancy, could sell for some money. This wire is
something like 3x8 mm in cross section. Very heavy stuff. So, if I
somehow manage to pull the transformer apart, I would, first, able to
throw the steel part to garbage, and second, to get and sell copper
wire. i would also keep some of this copper wire for home uses such as
grounding wire for my generator.

Without taking it apart I will not be able to do anything with this
monstrosity, not even throw it away.

This is a specialty transformer with lots of contacts, so I do not
think that I could sell it. (another, smaller like 50 lbs transformer
is an isolation transformer which I hope to sell for at least
something. Also, there are 8 1.2 farad capacitors)

So... How do I take it apart? It was assembled from steel plates, can
it be therefore disassembled?

Here in upstate NY, an entire lake was contaminated with PCBs by some guy
"salvaging" transformers at the shoreline. The fish are no longer safe to
eat. You may want to investigate further what may be inside that transformer
of yours before disassembling it. Perhaps your state's environmental
conservation department, or local department of solid waste could assist in
finding out more. Or, the manufacturer.

Jesus guyz. The friggin' thing is a "dry-type" transformer! There are no
(read my lips) ***NO*** PCBs in a dry type transformer.

The copper isn't worth more than 5 cents per pound. It is classed a mixed
copper and nobody wants it.

The laminations are usually and E and an I type on each layer reversed
positioned for each layer.

Question 1: Doesn't matter. I have no intention of disassembling them.

Question 2: Probably none, but none of the transformers in my home are older
than 3-4 years, except the tiny one that handles the doorbell. I doubt PCB's
are permitted in small household transformers at this stage, considering
what we know about them.

Question 3: The oil in older, larger transformers was there for either
cooling or insulation - I don't recall, and it doesn't matter, since it's
just a point of interest. But, the PCBs were there as a byproduct, not
because they had a purpose.

What's YOUR point? That, knowing what we do about these chemicals, we should
be stupid, pretend the knowledge doesn't exist, and be careless?

Nope. The chemicals were there to facilitate heat transfer,
especially in larger grid transformers. Needless to say,
non-conductive liquids with a high boiling point are required for the
task.

http://www.ehso.com/EHSO_PCB.htm

Characteristics and Uses of PCBs

PCBs belong to a family of organic compounds known as chlorinated
hydrocarbons. Key characteristics include: high boiling point, high
degree of chemical stability, low flammability, and low electric
conductivity. Between 1926-29 and 1977, PCB-containing products were
manufactured for use in applications where stable, fire-resistant,
heat-transfer properties were demanded. The most extensive use of PCBs
occurred in dielectric fluids. Such fluids typically have the
following characteristics: a heavy oil appearance, high boiling point,
high chemical stability, high flash point, low electrical
conductivity, and low water solubility. PCBs were also used as
plasticizers and additives in lubricating and cutting fluids. Most
PCBs were sold for use as dielectric fluids (insulating liquids) in
electric transformers and capacitors. Other uses included heat
transfer fluid, hydraulic fluid, dye carriers in carbonless copy
paper, plasticizers in paints, adhesives, and caulking compounds, and
filters in investment casting wax. Although PCBs are no longer
commercially made in the United States, many electric transformers and
capacitors once filled with PCBs are still in service. Additionally,
PCBs currently are being inadvertently produced as byproducts during
the manufacture of certain organic chemicals. PCB Manufacturers and
Trade Names lists some of the manufacturers, who made PCBs and the
trade names of their products.

Why Are PCBs Harmful to Human Health and the Environment
When released into the environment, PCBs do not easily break apart and
form new chemical arrangements (i.e., they are not readily
biodegradable). Instead they persist for many years, bioaccumulate,
and bioconcentrate in organisms. Well documented tests on laboratory
animals show that various levels of PCBs cause reproductive effects,
gastric disorders, skin lesions, and cancerous tumors. Exposure to
PCBs in humans can cause chloracne (a painful, disfiguring skin
ailment), liver damage, nausea, dizziness, eye irritation, and
bronchitis.

All minor ailments and no deaths have ever been attributed to it.

Reactionary? Nonsense. The OP stated that he has a transformer weighing
around 200 lbs. While this does not necessarily mean it's different from the
one in my furnace, dishwasher or doorbell, it also does not mean it's the
same. Neither you nor I know exactly what he has. You know that.

As far as "rational", I'm sure you're aware that there's an entire
generation that has no idea what sort of chemistry experiments went on in
this country before people finally woke up. Perhaps the Love Canal situation
was the wakeup call. It's entirely possible that the OP had NO idea about
what he might have in his possession.

Why do you have a problem with suggesting that he proceed with caution? Do
you believe that all the research into the dangers of PCBs are junk science?

There is no liquid in a "dry-type" transforemt and therefore no PCBs

PCB were only used in large transformers full of cooling oil for usage
indoors because of the flammablity rating of the PCB oils.

Did you know, **NO***, I repeat ***NO*** death has ever been related to
PCBs?

For those who are interested in a little of the history of PCBs I work for a
utility that has some experience with it.

Firstly, size doesn't matter, it was everywhere at one time, and ignoramus's
original post did not mention if the transformer was dry or not. So I think
Doug's response to be wary of PCBs was the right thing to suggest, given the
possible dangers involved.

PCBs were the answer to a maidens prayer for transformer and capacitor
manufacturers, since it had much better heat transfer characteristics
combined with excellent dielectric strength. Plus it allowed more compact
designs, and a cheaper overall product cost. All was well in transformer and
capacitor land until a couple of incidents that drew attention to some of
PCB environmental effects.

One incident, came about because PCBs look and smell remarkably like cooking
oil, somewhere ( Japan I think ) a barrel of it found its way into a
restaurant and it was used to cook food. A number people were hospitalised
from its effects, burning of the mouth, throat etc.

Another incident involved a fire in a basement substation in a high rise
building in the US. Although it is hard to burn, a fault in the transformer
set it alight, and the buildings airconditioning system pumped the smoke
from the fire through the building. PCB's produce dioxin when they burn, and
the building was contaminated with dioxin. I'm not sure the mess has ever
been cleaned up.

Once they started looking at the chemical, they found that it had the
property of being very stable, and of accumulating in the food chain. If
someone did dump it in a lake, it would still be in the lake 500 years
later, most likely in the fish at the top of the food chain.

Experience in our own area was with a customer who bought us a sample
capacitor to have tested. They had been asleep in bed, hot night with the
fan on, when a capacitor in their ceiling fan leaked PCB's on to them. They
had fairly serious skin reactions on their faces, necks, and legs, like a
reaction to strong bleach, although the reaction was not immediate. The
fellow who bought us the capacitor had the burns, so I've actually seen the
effects of pure PCB.

We removed all our PCB capacitors from our network, and replaced them with
non PCB types. We stockpiled these for disposal on an incinerator ship which
cruised the world destroying the PCBs by burning them at exteremly high
temperatures, to destroy the dioxin, out at sea, since it was too dangerous
to attempt it on land. Funny thing was the ships kept sinking, the cynic in
me thinks it must have been cheaper to load up an old ship to the gunnels
with the suff, and sink it rather than actually burn it.

While we had no PCB transformers on our network, we acquired a network which
did have some. The problem was that maintenance processes had cross
contaminated a lot of other transformers with the stuff, and at one stage
the EPA here had set a limit of 5 parts per million contamination of PCB
before the oil was clasified as hazardous. I believe it is now at 20 ppm. I
believe this to be a major over reaction to risks involved, it's the pure
stuff that needs to be treated with respect.

While there is a fair bit of hysteria surrounding PCBs, there are some real
risks with the pure stuff that people playing with old transformers and
capacitors need to be wary of.

John

Yes, definitly "Reactionay" in that you had NO Knowledge of the
transformer in question, and when others explained that ALL these
used in a FerroUPS, are DRY transformers, you still insist telling the
world, your prepositioned agenda. Actually, some of US do know exactly

They were intentionally used. As I understand it, PCB revolutionized the
transformer and capacitor industry when they were introduced. I seem to
recall that they were an excellent dielectric and had a very high flash
point, so fire hazards were reduced. They were a purpose made substance
sold under various trade names.

All you have to do is end up with a PCB filled transformer as I did for this
to come directly in to focus. Years ago I was given a "free" induction
furnace power supply. The donor had me sign a waiver because the supply
had a mercury spark gap included, but failed to mention that the
transformer, along with the huge capacitors, were filled with PCB's. The
law as stated at that time dictated that if any PCB filled device started
leaking, it was mandatory for the item to be disposed of by within thirty
day by proper procedures. I had to transport the power supply from one
state to another, and when it got there there were multiple wet spots from
the escaping PCB. Long story short, I talked to EPA to find out where I
stood and found out that it was illegal to dispose of such items by passing
them on to others, so I called the "donor" and informed him that he had a
serious problem on his hands. Disposal cost ran right at $3,000 for 800
pounds of transformer and capacitors, which was born by the donor. Don't

I'm not Doug, but oil is used in larger transformer for
cooling. PCBs were added to improve heat transfer. I have
no idea what the smallest size of oil filled transformers
are but larger ones are way bigger than 200 pounds. 8KVA
may be a little small for an oil filled transformer.

What types of transformers used PCBs, and what was the purpose for
the PCBs? Jon


I'm not Doug, but oil is used in larger transformer for
cooling. PCBs were added to improve heat transfer. I have
no idea what the smallest size of oil filled transformers
are but larger ones are way bigger than 200 pounds. 8KVA
may be a little small for an oil filled transformer.


Geez ig. You sure stirred up a hornets' nest here.
Getting to be one of those long (remembered) threads.
BTW what program/workflow gets those photos on line so fast? I Emailed you
at both addresses you posted but have had no reply.
Still interested in that starter motor?

Regards.
Ken.

Let me try to answer your last question. I'm no transformer expert,
but I worked in power plants my entire career. I know just enough to
be dangerous.

Generally speaking, large power transformers used PCBs. The liquid in
the transformer acted as a coolant that carried away heat to heat
exhangers of one kind or another. Most of them rejected their heat to
water or atmospheric air.

One of the ways to classify transformers is by their method of
cooling. O/A were oil/air cooled. O/W were oil/water cooled
O/A/F were oil/air/fan, etc. (I might be incorrect on that last one.
It might be O/FA.)

The PCBs were valued for their fire-suppressant properties. Thus, if
a transformer ever blew up there wasn't so much danger of fire.

Long before the days of environmental consciousness, folks who could
get their hands on transformer oil (PCBs) would slather it onto the
wood shingles on their houses. Not only would it help preserve the
wood, it would act as a fire supressant.

And now you've got a PCB-laden Superfund Site on your roof. :-0

I am demolishing a huge 8 kVa UPS. Lots of nice wires, screws etc.

It has a large transformer, it weighs around 200 lbs. It comes from a
that 8 KVA Ferrups UPS. There is a super heavy square shaped copper
wire on it, which, I fancy, could sell for some money. This wire is
something like 3x8 mm in cross section. Very heavy stuff. So, if I
somehow manage to pull the transformer apart, I would, first, able to
throw the steel part to garbage, and second, to get and sell copper
wire. i would also keep some of this copper wire for home uses such as
grounding wire for my generator.

Without taking it apart I will not be able to do anything with this
monstrosity, not even throw it away.

This is a specialty transformer with lots of contacts, so I do not
think that I could sell it. (another, smaller like 50 lbs transformer
is an isolation transformer which I hope to sell for at least
something. Also, there are 8 1.2 farad capacitors)

So... How do I take it apart? It was assembled from steel plates, can
it be therefore disassembled?

Here in upstate NY, an entire lake was contaminated with PCBs by some guy
"salvaging" transformers at the shoreline. The fish are no longer safe to
eat. You may want to investigate further what may be inside that transformer
of yours before disassembling it. Perhaps your state's environmental
conservation department, or local department of solid waste could assist in
finding out more. Or, the manufacturer.


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?

Actually, I'd like to know WHO the guy was, not how he is. Please provide a
way of contacting him, since you seem to be privy to all the information
surrounding this event.
