Taking apart a large transformer
"Ignoramus22732" wrote in message ... 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? i 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. |

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. 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. |

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.

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 take PCB's lightly. Harold |

"Ignoramus22732" wrote in message ... I have some large capacitors also, how do I know if they have PCBs? i These are likely candidates for PCB, depending on their age. They should be labelled with a date code; anything prior to 1973 will contain PCB. If you care to post all the capacitor label information here, I can probably determine yes or no. -- Regards, Chas.

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.

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? 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. regards, John |

No deaths? OK. But, why is it considered dangerous?

How many transformers do you have in your house, Doug? How many of those contain PCBs? What types of transformers used PCBs, and what was the purpose for the PCBs? Jon 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? My point is that I suspected you of being a reactionary man who is unable to consider a topic rationally, based upon the facts in evidence, without launching into a pre-programmed tirade based upon emotional supposition and lack of knowledge. That you are unwilling to answer the very basic questions that I asked you WRT transformers further demonstrates this, and I thank you for further revealing yourself with your response. I can't "fix" the problems that you seem determined to expose to the world, Doug,, but perhaps you would be a bit better off it you would at least educate yourself a bit before exposing your ignorance in any particular area of knowledge. Of course, you might very well enjoy espousing your ignorance to the world; it seems to be a popular pastime with your type. Jon 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? |

u... 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. I've heard OLD veteran teachers say they think there's something in the water - people no longer have reading comprehension skills. Luckily, you and two others here seem to escaped this fate. |

The historical aspect of this just HAS to be remembered. ================================================= Only metric prefixes for 10+6 or more have an upper-case abbreviation (e.g., M = 10+6, G = 10+9, etc.). In particular, note that the prefix m indicates 10-3 and M indicates 10+6. The difference between an upper-case M and a lower-case m is nine orders of magnitude! One should be warned that American manufacturers of capacitors often use "mF" or "MF" to indicate microfarads, a practice that is both incorrect and misleading. http://www.rbs0.com/tw.htm ================================================= mike |

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? i 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. Thanks. Hm, all that is inside this transformer is steel, copper, varnish, and paper. Maybe you are referring to hyooge transformers filled with liquids? In any case, I will appreciate input regarding this issue, as I do not want to run afoul of the laws. i Yes the PCB problem is related to oil filled transformers. if you can ID it you should be able to get the specs from the manufacturer to determine if it is oil filled or dry (maybe you already know). If it is dry then no problem. If oil filled and has PCB, make UPS take it back since they shouldn't have given or sold it to you. |

It would seem that if they were made using the same technology, they would need to be like 250 times bigger than my capacitors! They are electrolytic capacitors and use a carbon aerogel as one of the "plates". Aerogels have a very large surface area per volume. Anthony |
