Especially transformer fires are extremly compli-
cated to extinguish. In the majority of cases, the
transformers cannot be accessed from the outside
and the burning transformer oil bears a high safety
risk for the firefighters.
A precise firefighting requires on the one hand
an efficient extinguishing agent and on the other
hand an at least pre-assembled possibility for foam
injection.
With the innovative One Seven® system Gimaex has
a highly efficient and safe extinguishing system
which is approved for electrically plants.
Moreover, the know-how for stationary or half-stati-
onary compressed air foam applications is provided.
This is the solution for a successful and fast firefigh-
ting of such complicated fires and therefore it avoids
long downtimes.

One Seven® - Dry Foam
Test procedure according to European standard
EN 3-2/1999
The following values have been determined:
35 kV/50 Hz 99,6 µA at Dry Foam
35 kV/50 Hz 1247,0 µA at Wet Foam
The application of a One Seven® 1.5" (C) nozzle
with One Seven® Dry and Wet Foam in electrically
plants of up to 35 kV had been tested and certified
by the accredited laboratory "VEIKI-VNL Villamos
Nagylaboratóriumok Kft. Tanúsitási iroda".
When applying One Seven® at electrically
plants with a voltage of up to 35 kV, a minimum
distance of 4 m must be kept.
One Seven® Wet Foam
A foam spaying nozzle system has to be installed for the application in transformers stations to provide a gapless covering with One Seven® Wet Foam for efficient and sustaining extinguishing of the burning transformers oil in shortest time.

Protection target:
The transformer stations are located inside the
production building at different floors. Due to the
appropriate design of the extinguishing sectors it is
possible to effectively protect all substations from
the control station.
One Seven® flat jet nozzles will be used as discharge
installations for optimum compressed air foam
covering.
