Multifunctional Modules (MFM) for 72.5 - 420 kV

Customized, factory assembled substation equipment for permanent or temporary electrification

Multifunctional Modules (MFM) are capable of combining various functions in a single product application, such as:

  • High-voltage switchgear
  • Power transformer
  • Medium-voltage switchgear
  • Control and protection

MFMs cover a range of equipment for electrical installations, completely assembled and tested at the factory, easy to transport and install. Combining the modules makes it possible to create any type of mobile or fixed station.


  • Integration of renewable power to the grid
  • Rapid or temporary substation applications
  • Power supply
  • Power generation

Why Hitachi Energy?

  • The MFM concept enables significant reduction in construction and engineering time for substations
  • The compact design allows for transport with conventional methods
