Product Description

Product Detail

1. Product Display

Electric furnace transformers are transformers which supply power to the electric furnaces.
It can drop high voltage to the working voltage the electric furnaces need.
There are many kinds of electric furnaces,so there are many kinds of electric furnace transformers cooperating with them.
Now,our company manufactures following electric furnace transformers:

1 electric furnace transformers used in steelelectric furnaces(including on-laod,no-load and enclosed reactor) ;
2 mineral hot furnace transformers used to smelt kinds of iron alloys,hydrosilicons,carbides,etc(single phase,three phases on-load and no-load tap changer).
They are low loss and energy-saving products.Cooling methods are self-cooling, forced oil water cooling, etc.It can be designed specially according with customers' requirements.
