The hermetically sealed transformer is the transformer of which inner tank is totally isolated from the outside
atmosphere,its volume changes with shrinkage and expansion of the corrugated tank sides.Moisture and
oxygen can not enter the tank from outside,thus slowing down the aging of the insulating material.

Ladle transformer is used as ladle power transformer. Using high power electric furnace, the furnace and
continuous casting and rolling refining outside "quaternary" process equipment, it is the development direction
of Chinas steel enterprises.

Series Reactors are used in Electric Arc Furnaces (EAF) to provide furnace operation with longer arcs, lower currents and lower electrode consumption. Such reactors are very useful in the first melting period. With the molten scrap, the absence of the series reactor would allow higher power transfer to the EAF, reducing the tap-to-tap cycle, thus increasing productivity.

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.
