Richard and All: 

Attached are the Howard Ind. comments related to the use of Amorphous Metal being used in 

liquid immersed distribution transformers. 

We manufacture both the silicon core transformers and the amorphous metal core transformers, 

both are liquid immersed units. Hopefully these comments will be informative and helpful to 

some of the members of our committee. (See Attachment)
