Special transformers for Railways

Our transformers are designed to withstand high mechanical stresses due to fluctuating load current and frequent short-circuits created by passing trains. With rated power up to 40 MVA and connection to HV up to 110kV, we can propose solutions for all situations.

To improve transmission efficiency and system regulation while reducing earth current and electromagnetic interferences, Setrans Holding proposes a full range of specific medium power transformers dedicated to railway power supply:

  • Standard Power Transformers
  • Autotransformers
  • Power Feeding Transformers

Electrical Arc Furnace

EAF Transformers operate under very severe conditions with regard to frequent overcurrents and overvoltages generated by short circuits in the furnace and the operating of HV circuit-breaker. SETRANS HOLDING compact and low-weight transformers fully comply with the customers’ specifications. They are rigorously adapted to support extreme thermal, mechanical and dielectric constraints of the furnace load cycle.

Electric Arc Furnaces (EAF) can be either of AC or DC arcfurnaces.

Rectifier Transformers

Especially designed to supply the extra-high currents required for industrial applications such as electrolysis and electrochemical processes, Setrans Holding proposes a complete offering adapted top both new or refurbished installations.

APPLICATIONS

Electro-intensive industries

  • Steel furnaces
  • Ferro-alloy furnaces with short or submerged arc
  • Smelting of other marerials
