Transformers
Transformers are one of the primary components for the transmission and distribution of electrical energy. Their design results mainly from the range of application, the construction, the rated power and the voltage level. There are also various special purpose transformers such as furnace transformers, which are basically in the range of power transformers as far as rated power and rated voltage are concerned. Furnace transformers are characterized by very high secondary currents and wide secondary voltage regulation in order to cope with the furnace needs, depending on the particular kind of cycle requested.
For many years, Electrical Arc Furnace (EAF) power transformers have been meeting very high supply needs of the steel industry's arc furnaces around the world. EAF transformers are suitable for steel furnaces, ladle furnaces (LF) and ferroalloy furnaces. They work under critical and severe conditions caused by overcurrents and overvoltages generated by short circuits in the furnaces. Arc furnace transformers are used for melting scrap metal. Usually when there is an EAF there is also an LF that is used to refine the metal melted by the arc furnace. Such kind of transformers are three phases.
We have experience in supplying the following types of transformers:
| Three phase (EAF) transformer | 90 MVA |
|---|---|
| Three phase (LF) transformer | 18 MVA |
| Three phase (LF) transformer | 13 MVA |
| Three phase (POWER) transformer | 63 MVA |
| Three phase (EAF) transformer | 45 MVA |
| Three phase (EAF) transformer | 85 MVA |
| Three phase (EAF) transformer | 130 MVA |
| Three phase (POWER) transformer | 160 MVA |
| Three phase (LF) transformer | 24 MVA |
