User Manual
TRANSPORT AND HANDLING
STORAGE/
The storage area must maintain the necessary cleanliness and
safety conditions so as to avoid damage to the transformer.
Follow the safety markings on the packaging at all times.
›
Storage in vertical position
: The transformers can be stored in
an upright position after unpacking and must always be firmly
anchored to the ground without any time restriction.
›
Storage in horizontal position
: The transformers can be stored
upright in their original packaging, which was designed to
this end, for a of limited period of time. We recommend not
keeping them in this position for more than 6 months if stored
outdoors, or 12 months if sheltered from bad weather. In any
case, they should be placed on firm, horizontal ground.
The final holder will be responsible for delivering the used
packaging or its waste for environmental management according
to the legislation in force in their country.
Unpacking
: Remove the top and sides of the box, if any, to allow
free handling of the unit.
Annex I,
contains the figures mentioned below.
If the transformer is in a horizontal position, to place it in a vertical
position, proceed as indicated in Fig. 1 and Fig. 2. During the lifting
process, the slings must always be kept in an upright position.
When the device is in a vertical position, movements can be
made:
› If the tank is
not equipped
with lifting eyes, as shown in Fig. 3.
› If the tank
is equipped
with lifting eyes, as shown in Fig. 4.
Once the equipment has been placed in an upright position, a
visual inspection is suggested so as to detect possible damage.
Precautions will be taken throughout the process to avoid
damaging the sheds of the synthetic insulator.
TRANSPORT/
ARTECHE’s packaging guarantees a correct transport to
destination.
These transformers can be transported both horizontally and
vertically. For transport, the transformer should be properly
attached to the packaging so as to avoid movement.
› Load and unload the transformer slowly and avoid sudden
movements.
› It must be secured to the truck to avoid movement.
› Keep truck acceleration under 5G, and the speed under:
• Unpaved road ___________ Max. 30 km/hour
• Secondary roads ___________ Max. 60 km/hour
• Highway (motorway) ___________ Max. 90 km/hour
DANGER
INJURIES from falls and tipping
› Do not place the equipment upside down or on its side

RECEIPT/
After receipt, check the packages for signs of shock, tampering,
etc. Any anomaly must be indicated on the transport
company’s receipt sheet and communicated to ARTECHE or
the equipment supplier.
Once the transformer has been unpacked, check that none of
the screws holding the insulator have become loose during
transport. If they have, tighten them according to the torque
indicated in
Annex II
. If any other type of anomaly appears,
inform ARTECHE or the supplier of the equipment.
Attach photos of the damaged transformers to the report.
