Product Description
Electric furnace transformer
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 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.
The model of the electric furnace transformer is expressed as follows:
Meaning: H-steel smelting arc furnace, HJ-ladle fining furnace, HZ-electroslag furnace, HC-calcium carbide furnace, HK-blast furnace, HG-industrial furnace
Number of phase: D-single phases, S-three phases
Type of cooling devices: oil immersed self-coiling- air cooling F, water cooling S
Way of oil circulation: natural circulation, forced oil circulation P
Way of voltage regulation: non-excitation voltage regulation, load ratio voltage regulation
Built-in accessories: flux leakage changing group-,built in reactor K
Rated capacity: kVA
Voltage class: KV
