Standards/regulations that the transformers almost certainly don't meet, produced in factories that don't follow any standards or regulations, and then add in the cost and delay in shipping something like that.
replyMaybe.

If I were to desperately need a power transformer, I'd consider going down this route in parallel to waiting for years for a "blessed" one.
China has the most sophisticated grid in the world, and is spending $100B a year on expanding and upgrading. They have a uniquely high share generated by renewables. It runs 800kV and will go higher after the upgrade. The first Small Modular Reactor will come online this year. If you think that’s all just being built in random factories without standards you’re very much mistaken.
replyChina's energy generation mix is not uniquely high in renewables! Where on earth did you get that idea from? China has about the same % renewable generation as Australia, about 1/3rd. Brazil has 80%, Norway 90%, some have near 100%.
replyWhat China does have is a very high carbon emission intensity of electricity generation thanks to over half capacity coming from coal.
How does the carbon intensity affect transformer operation or are you just adding non sequiteurs?
replyI was replying to a comment that brought up renewables. I can be of further assistance to help you follow the chain of comments if you let me know what part you're struggling with exactly.
replyAnd yet somehow the biggest electric grid in the world is running on them just fine.
