Transformers for ore-smelting furnaces
Main | Our products | Electric-furnace transformers | Transformers for ore-smelting furnaces

Ore-smelting furnaces have the widest nomenclature among Electric units, due to a large variety of brands of commercial products manufactured as well as applied technologies (only electric resistance furnaces have a wider range of units).

Regenerative processes in the furnaces require low secondary voltages and high currents. In addition, depending on the melted material it is necessary to change the regime of the furnace, i. e., to regulate voltage and amperage in wide ranges.

The company "Electrical Machines" produces a wide range of transformers for ore-smelting furnaces for different purposes: single-phase and three-phase, at primary voltage 6-35 kV, with the regulation under load (RUL) and power range from 4000 to 29,000 KVA.
