Furnace Transformer Main Functions and Features 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 on-load-tap-changing Arc Furnace Transformers Technical Parameters Rated power (KVA) Primary Voltage (KV) Secondary Voltage (V) Secondary Step Voltage (V) Rated Secondary Current (A) Regulation Voltage Step Connection symbol short-circuit Impendance(%) Cooling Method Invariablenes Power Invariablenes Current10000 35 66 280 240 240 100 10 24 056 5 Steps Invariablenes Power, 14 Steps Invariablenes Current Ddo Yd11 Ynd11 7 8 OFWF OR OFAF 12500 314 270 270 116 11 26 729 16000 353 305 305 137 12 30 287 20000 35 66 110 392 340 340 158 13 33 962 6 7 (35KV) 7.5 8.5 66110KV 25000 436 380 380 184 14 37 984 31500 489 425 425 201 16 42 792 40000 547 475 475 223 18 48 619 50000 610 530 530 250 20 54 467 63000 673 585 585 277 22 62 176 80000 760 660 660 310 25 69 982
