Top Comments of this video!! :3
Until watching this video, I didn't realize that the insulators (bushings) on modern transformers are made out of plastic instead of porcelain. What is truly amazing about these pole transformers is that they are so reliable that they will easily keep working for decades without any servicing or maintenance. The really old pole transformers found in many US cities have long outlived the people who made and installed them!!

Thanks for posting, I never realised that so little material was used in these transformers.

LOL I'm the one who sent in the request to see this on the "How It's Made" website. :) Was awesome to see it make air. :)
|
Neat, I always thought they were wound in an almost cylindrical kinda shape that matched the shape of the tank, and a round iron core... Never would have thought its your "standard looking" transformer in a tank like that..

This is our favorite TV show!
|
Thanks for shareing this.. I have always wanted to see the details on one of these pole pigs, and how they are built
|
I use to work in the industrial power field (mainly reclosers) and have serviced several transformers. I've never seen thermoplastic busings on a transformer before. I'm fairly certain the the busings seen in this video were ceramic bushings, at least the primary was, couldn't see the secondaries very well.

When the assembly is baked and the glues sets, the winding are bonded together achieving very high strength. This is important, because in power distribution systems the amount of power and prospective fault current is typically thousands to tens of thousands of amps, if a short circuit appears on the secondary of a transformer the magnetic forces applied on the windings within the transformer can physically rip the windings apart. So the high strength glue stops this from happening.

was hoping I'd see this again after seeing it on tv

Very enlightening; thanks for posting.

This is small single phase primary to split phase secondary may be 25KVA@2% . This video has been handy and now I use aluminium sheet coil for my low voltage secondaries as it way cheaper than copper. The core steel sheet material that ABB are using is a high quality material that can run at a high flux levels like 1.5 Teslas with very low core power loss, meaning you get more volts per turn, so less turns of wire are needed, better regulation.

Don Smith had the whole setup from generation to your wall socket on a kitchen table running.

I work at a transformer factory in Norway which was owned by ABB and I've always wondered how these small transformers were made.
|
i love this video, we always wonder how these transformers work,
i have seen some blow up, those are the best ones on youtube,
thanks for posting your video, KaBooooooom , because Stephen said so
|
cool video.
|
The primary carries high voltage, low current, so it is the many turns of relatively small wire. The secondary is lower voltage, higher current, so it is the aluminum sheet. You can also tell because the lead wire is connected to the high voltage bushing on top of the transformer can.

Oh it is attached to the case of the transformer. Different design than I have seen. thx
|
Interesting vid, I like the aluminium sheet secondaries! There's barely any turns of those, but then it is a big stepdown ratio, probably 16kv to 110v? Some comments in the voice over are a bit odd though, "high voltage current" and "electrical steel"?!
|
Excellent!

Since I was a teenager I have always wondered what was inside of the transformers. Thank goodness for videos on YouTube 22 years later for a thorough presentation of the inner workings of a pole transformer. π
