Sub Merged Arc melting furnace transformers are manufactured in 3 phase system upto 12.5 MVA and Bank of 3 nos, single phase, transformers for higher than 12.5 MVA transformers.
If the secondary voltage of the Transformer is a high voltage, it is called as Power Transformer. Makpower supplies power transformers which transform energy from higher voltage levels and to distribute this energy to lower voltage substations or directly to large industrial consumers.
These are used for melting of metal however recently the secondary supply of specified voltage is directly fed to the induction furnace coil.
