Industrial & Railway Transformers
GE’s industrial and railway specialized transformers portfolio includes a wide range of rectifier transformers for electrolysis process of metal or chemical industries, as well as AC or DC Electrical Arc Furnace (EAF) transformers. With expertise in products up to the highest ratings in the world, GE’s references include rectifier transformer combinations above 80 kA DC current ratings and EAF transformers up to 300 MVA.
GE’s rectifier transformers are especially developed for industrial applications such as electrolysis process for aluminum or chemical ones for zinc, copper or chlorine. With more than 40 years of experience supplying rectifier power transformers to more than 80 industrial projects all over the world, GE has developed unique skills and experience to propose solutions adapted to specific industrial processes. We offer a complete range to for your rectifier:
Electrical Arc Furnace Transformers
GE is a leader in extra-high power EAF transformers, and the quality and performance of our products are field-tested every day at steel production sites around the world. Arc furnace transformers deliver high currents over a wide range of voltages. While power ratings between 10 and 300 MVA and secondary currents of more than 100 kA are quite common, our EAF transformers are precisely adapted to the extreme thermal, mechanical and dielectric constraints of the furnace load cycles. In order to improve the efficiency of the service currents and to maintain the system's stability, furnace series reactors may be also added, which can be housed in the same EAF transformer's tank.
Trackside transformers are railways' key components that supply power to electric rolling-stock that use either DC or single phase AC networks.
These transformers are designed to withstand the mechanical and electrical stresses due to inherent fluctuating load current characteristics and frequent short circuits conditions created by passing trains. GE's trackside transformers can reach up to 60 MVA rated power and with the HV connected to 220kV or even 400kV networks for high-speed train supplies.
