3.6. ASSEMBLING TOOLS
Proper assembly of the PF Modular Transformer Substations requires the following elements
to be available:
PF Assembling Prop (
reference 160028
)
The number of required props depends on the number of modules forming the
enclosure. PF-203 requires 3 props; PF-304 requires 4 props; PF-305 requires 5
props, etc.; therefore, the number of required props equals the number of modules
making up the enclosure.
1 ratchet wrench set
1 low-profile ratchet wrench (
reference 394253-31
, ‘PF Assembling Ratchet’)
2
ladders
1
brush
1 set of spanners and screwdrivers
Painting utensils, for painting the transformer substation or for retouching painted
panels.
For correct assembly of the panels, the enclosure foundations must be levelled with the
greatest care according to the instructions in section 3.4.
3.7. PF ENCLOSURE ASSEMBLY PROCESS
By way of example, the assembly process for a PF-205 enclosure with 2 transformers and
1 personnel access door is explained below.
The panels used to assemble the PF Modular Transformer Substations are grouped into two
classes,
according to how they are assembled
:
a)
Horizontally-assembled panels:
These are the bottom plates, floor plates and

b)
Vertically-assembled panels:
