Description
Feature
An electric furnace transformer is used to supply power to an electric furnace, which lowers the high voltage to the furnace-required lower voltage.
Its type varies with the type of electric furnace, so the transformer has many types. Currently we manufacture following types: Arc furnace transformers used for steel-smelting (including load-ratio voltage regulator type, no-load voltage regulator type, and built-in reactor type); Blast furnace transformers used for smelting of iron alloy, silicides, calcium carbide (single phase, three phase, load ratio voltage regulator and no-load voltage regulator). All are energy-saving products with low power loss. The cooling modes are self-cooling mode, forced water cooling mode, etc.And we can also provide the special transformer by the customer's demands.
