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.
