Thinking about bidding on this auction.
I did a search on the forums and found this thread.
Is there anyway to check that the windings would be copper as opposed to Al? Also how would you go about disposing of the oil? I am assuming that there are no PCb's, in the oil at least.

Is it just me and my lack of sleep, or does that look like 3 robot girls?
I'd make **** sure there were no PCBs involved. My brother got into some transformers like these. He ended up needing a lawyer. Just sayin...
Yes, you are pretty sure of the oil not having any pcb contamination, since they were built in 1998. The nameplate says this. You can look at the nameplate photo at the auction site.
Aluminum windings: Take a close look at the nameplate. Both the primary and secondary windings are aluminum, it says that right beside the manufacturing date.
The transformers probably have some resale value as the seller says they are in working condition.
You would also have 100 gallons of mineral oil to sell...waste oil is used by some as shop heat or conversion to biodiesel but I don't know if any of that kind of use is even legal in Ca.
Good luck,
Jon.
man I have a lot of experience in this. My uncle became a millionaire scrapping those (like u picture). Don't worry about pcbs, there are plenty of places that will buy the oil. Just make sure u drain it into 55 gal drum for them to pump from. Next thing is this- in the late 90's they started winding transformers with aluminum wire to save money (resulted in massive black-outs), but most before or since are wound with copper. there are brass bushings inside most that make up a lot of their weight (which is what copper/aluminum is attached to). If not totally damaged, the tanks can be resold to local transformer companies. Its very valuable if u do it right. But; do it wrong and you'll be hit with $1m cleanup fine from EPA. just contain all oil and let highest payer (usually $.025 per gal) come haul it off. there are plenty of oil buyers. just Google "used oil buyers". Hope I was able to help. Arky
BTW, the standard for profit on transformers is $.50-$1.00 per Iva. I just realized u have 3 50kva's. Wow! What a find. You should definately NOT bid above $1 per kva. unless u can secure deal with local transformer manufacturer to buy them. maybe pm me? I have relatives in that business. Arky
arkansasjunkman:
Thank you for the knowledge drop. I doubt that I am going to purchase them. I have no way of transporting them let alone storing them to work on.
At least for the time being. However, I was immensely curious if hypothetically I was going to purchase them.
Thank you again.
They have a manufacturing date of April 1998. PCB's were banned in 1979, I would not worry about them.
There are also big stickers on those that say "no PCB's". :)
