The PFU Transformer Substations consist of a concrete monoblock-structure enclosure that houses all electrical switchgear fromMV switchgear to LV switchboards, including transformers,control devices and interconnecting equipment for the various elements.The main advantage of these Transformer Substations is thefact that both the construction, assembly and built-in equipmentcan be entirely factory-built, thus ensuring uniform quality andsignificantly minimising any on-site construction and assemblywork. In addition, the careful design of the substations allowsthe substations to be installed...

PFS Transformer Substations feature a monoblock structure andhave been designed for underground installation and can housedifferent electrical power distribution arrangements, makingthem suitable for public distribution and private installationload-centre substations.The underground installation and the easy adaptation of thesubstation area minimise any environmental impact.Depending on the ventilation system, two different versions areavailable: PFS-V (vertical grille ventilation, protruding) and PFS-H (horizontal grille ventilation, non-protruding) > 3040 200+50 29003700Concrete Slaband...

PF Transformer Substations consist of different prefabricatedconcrete elements that are assembled on-site to create a buildingthat houses all electric switchgear: from the MV switchgear to the low-voltage switchboards, including transformers, controldevices and interconnecting means for the different elements.The modular structure allows Transformer Substations to beeasily transported for installation in hard-to-access areas andpermit any arrangement of the Transformer Substation to beimplemented, including the number of access doors andtransformers required for each application....

The ORMASET is a packaged Transformer Substation that hasbeen designed for half-buried installation, incorporating MV switchgear with SF > 6 as insulation and interrupting medium( CGM/CGC ), a transformer, a LV switchboard as well asinterconnecting and auxiliary devices.Its careful outdoor design, compact size and half-buriedinstallation (visible height 1.5 m) reduces the substation visual impact, making it suitable for both industrial and residential areas.

Installation of a MINIBLOK requires digging a trench of thedimensions shown in the figure. The trench foundation should be levelled by a compacted sand layer on which the packaged substation will be placed.Installation operations consist of positioning the packagedsubstation on the dug trench and connecting the MV and LVcables and the outside earthing network. The knockout holesprovided on the enclosure should be drilled so this can be done.After bringing these cables in, the cable service entrancesshould be sealed to prevent water from entering the substation, before the trench is covered....

MINISUB-V model prevents rainfall and even surface waterfrom entering the enclosure until it reaches an approximate height of 200 mm. In the MINISUB-H model, manholes areavailable that can be coupled to the general rain water sewer to remove water that enters through the grilles, thus preventing it from entering the Transformer Substation.In addition, the use of SF > MINISUB is a compact packaged Transformer Substation thathas been designed by Ormazabal to be used for public MV distribution networks. The substation has been designed for underground installation.Inside the compact concrete...
