Dear Readers,
At the beginning of the year, I would like to reflect on the main market information related to the shortage of transformers. Obviously, 2023 was an exceptionally good business year for manufacturers of transformers, materials, components, etc. Most factories are filled with orders for the next two to three years or even longer, which is significant progress after 15 challenging years, although the situation is not the same in all parts of the world.
