That's a good point. The AI slop video is inaccurate, but entertaining.
For comparison, here's the real deal - transformer winding at Virginia Transformer in the US.[1]
That video provides a good sense of why these things take so long to make.
All those wooden parts. All that slowly and carefully hand wound heavy wire. As they point out, if that wire can move at all, as the magnetic fields pushes and pulls on it, the vibration will, over time, wear out the transformer. It's a very fussy job to get the position and tension right, with wire firmly supported against movement in all directions. That's the difference between a lifetime of a few years and many decades.
It's a boring video.
Here's the whole manufacturing process at ETD in the Czech Republic.[2]
This shows roughly the same sequence of steps as the fake video, but it's real.
Big industrial bay with lots of transformers and overhead cranes. Sheets of lamination steel.
Winding. The moving and shipping of the big transformer.
All that is in both the real video and the AI slop.
This is the real video from the manufacturer, and it assumes that if you're watching, you know what you're looking at. There's little narration.
It's a confusing video.
Here's a small open frame transformer.[3] If you've done much electrical or electronics work, you've seen one, and may have replaced or installed one. When you see the big ones being built, the process makes sense. Same concept, with a laminated core, windings, insulation, and lead wires. The big ones have the same key parts, just much bigger. But if you don't know a transformer from a transistor, the manufacturer videos are just wallpaper.
And there's the problem. The AI slop version will give the average viewer a general idea of the process. The accurate videos from manufacturers require more background knowledge to comprehend.
The target audience is different. The manufacturers don't make those videos for the general public.
