MFM – Multi Functional ModuleMFM 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 MVAMFM 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 MVAThis 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 SubstationsThe lifting system allows the MFM module to be positioned on the trailer, thereby forming a mobile substation.

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.

Application examples

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.
