MFM – Multi Functional Module
MFM Modules 72.5 kV - 170 kV
MFM is the new modularity for building
substations. A range of modules fully
assembled and tested in the factory and
designed for easy transportation and
installation.
Multi Functional Modules 72.5 kV - 170 kV, 40 MVA
MFM 00 and MFM 0 are the most compact and complete
Multi Functional Modules available. They are an excellent
solution for permanent or temporary electricity distribution or
generation installations.
The use of MFM modules enables a considerable reduction in
installation times and requires minimal civil works.
The compact dimensions allows for transportation with normal
semi-trailers.
The ease of loading/unloading from the semi-trailer facilitates
positioning of the modules even in the small clearance areas
of the high voltage line.
The MFM modules may be customised by means of
software and hardware applications, they may be fitted with
accessories such as wheels for road transport, lifting and
levelling systems, monitoring and remote control systems, etc.
Multi Functional Modules 72.5/12 (17.5) kV, 40 MVA
This type of module is fitted with surge arresters on the
high voltage side and it is set up for connection to the
electrical network by means of aluminium cables. It is also
available with MV switchgear with a rated voltage of up to
24 kV, thereby forming a complete and autonomous HV/MV
transformer station in a very small space.

Transportability
The MFM modules offer excellent transportability. The overall
dimensions are such that the modules may be transported by
normal commercial vehicles and, thanks to the provision of a
lifting system, the operations for the loading, unloading and
positioning on site can be carried out without the need for a
crane or lifting gear.
Mobile Substations
The lifting system allows the MFM module to be positioned on
the trailer, thereby forming a mobile substation.

Application examples
Substation example for distribution or generation
networks
The figure below shows how a connection may be made to a
HV electrical network by using a SCRI(*) module in an IN-OUT
configuration and a MFM module.
The SCRI module is positioned in the clearance areas of the
HV line and connected in series to the line itself. The MFM
module achieves the MV transformation and distribution.

The modules are complete with a protection and control
system. In the same way, it is possible to connect “dispersed”
type generation systems (e.g. on-shore wind farms and
photovoltaic systems) directly to the HV line.
(*) The SCRI modules are Substations for Connection with Rapid Installation
which drastically reduce the time necessary for connection to the HV network, do
not require building works for installation, are very compact, transportable without
escorts and offer enormous flexibility of use in the case of both emergency and
permanent installations.
