D-single phase,S-three phase electric arc furnace tracsformer

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.

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.
