1500kva Electric Arc Furnace Transformer •Main function and features Furnace transformers are separated with normal power transformer with its characteristic of massive secondary currents which are the main products of yuanguang Electric with many advantages both on quality and price. As an example a 30MVA unit at 150V would result in a secondary current of 115 kilo ampere. For these high secondary currents special bushings are required to be connected to the bus-bars. These bushings are specified with very specific arrangements to suit the bus-bar arrangement and cooling system. Furnace bus-bar are mostly water-cooled. The cooler are either of the oil forced (OFAF) or Oil forced water OFWF). yuanguang electric is renowned and appreciated by its reliable products performance and integrated services. Brief specification: 1) Voltage class: 6~110 KV 2) Capacity : 630 KVA to 120,000 KVA 3) Short-circuit impedance : 4.5~21% 4) Losses : No-load losses is fully comply with IEC standard requirements 35kV Arc Furnace Transformer Technical Parameters
