The highest voltage level of dry-type transformer, whether there is 110kV and above dry-type transformer

1, the highest voltage level of dry-type transformer, whether there is 110kV and above dry-type transformer.

Dry-type transformer is usually the highest level is 35kV, but there are domestic manufacturers have produced 110kV dry-type transformer (more than a decade ago, Shandong Jinmank has produced, Huapeng seems to have produced 110kV dry-type transformer, but the application of very few)

2, whether there is more than 100kV amorphous alloy transformer? Amorphous alloy transformer has a lot of traditional silicon steel transformer does not have the benefits, why not promote the use?

Amorphous alloy transformer due to the special core material is not possible to produce large power transformers. The advantages of amorphous alloy transformer is its very low control loss (can be compared to ordinary silicon steel sheet core transformer air loss down 60 to 70%). But because of its material is very thin, and brittle, processing difficulties, can not be used for the production of large-scale power transformers, at present only in the field of distribution transformers have certain applications. And its cost compared to ordinary silicon steel sheet core transformer is quite high. Usually more than ten years to recover the cost difference.
