General Instructions
ormaset
Kiosk-type prefabricated transformer substation
Storage
8. Storage
Storage of
ormaset
must be carried out so as to avoid any
rainfall or sunlight falling directly on the internal electrical
equipment. Store in a non-aggressive environment.
The recommended conditions are as follows:
1.
Environmental air temperature should not exceed
55 ºC and its mean value, measured in a period of
24 hours, should not exceed 35 ºC.
2.
The environmental air temperature should not drop
below - 15 ºC.
3.
The switchgear must be protected from direct solar
radiation.
4.
Maximum altitude is 1000 m.
5.
The environmental air must not have any significant
contamination from dust, smoke, corrosive and/or
inflammable gases, vapours or salt.
6.
The switchgear must be protected from the rain, and
the humidity conditions should be as follows:
a.
The mean relative humidity value, measured over a
period of 24 hours, must not exceed 95%.
b.
The mean water steam pressure value, measured
over a period of 24 hours, must not exceed 2.2 kPa.
c.
The mean relative humidity value, measured over a
period of one month, must not exceed 90%.
d.
The mean water steam pressure value, measured
over a period of one month, must not exceed
1.8 kPa.
7.
During transport, vibrations caused by external factors
or seismic movements must be insignificant.
Any other conditions must be notified beforehand,
since the equipment must be factory-adjusted to the
environmental pressure at the final destination or
during transport. If this is not the case, the manometer
needle of the medium voltage switchgear may indicate
an incorrect value, even if the equipment's internal gas
pressure is correct.
