5. Dispatch and storage
5.1 Packing and transport
WARNING
Follow the symbols and instructions shown on the
packaging carefully.
For shipping reasons, the switchgear is usually
dispatched in 1000 mm-long sections.
In case of switchgear lengths exceeding 1000 mm,
several sections must be provided and the cubicles
must be coupled in the installation room. No special
devices are required, as assembly is carried out by
aligning all the relevant sections. In order to prevent
any damage during transport, the most fragile
auxiliary equipment (protection and control relays and
measurement instruments) can be removed and
packed separately.
This equipment must be carefully checked on receipt,
packed again and properly stored until final
installation. Please refer to the relevant apparatus
documentation for correct installation.
Each switchgear section (or unit group) is packed
according to the customer’s shipping and storage
requirements. Each group is protected by a plastic
wrap so as to avoid any water infiltration while loading
and unloading and to protect each component from
dust while stored.
The vehicle for transporting a unit group must be fitted
with an anti-slip, friction-resistant loading platform no
higher than 1.5 m and the total vehicle height must not
exceed four metres.
The compartment groups must stand back to back and
their rear parts must be separated by insulating,
compression-resistant materials so as to avoid any
direct contact between the surfaces of the different
units. Moreover, each group must be separated by
means of frames so as to avoid any movement during
transport.
The groups must be fixed to the vehicle by means of
ropes so as to avoid any violent impact or tilting over
in the case of sharp turns or sudden stops. Moreover,
the vehicle must be fitted with a canvas covering the
whole load. The load capacity of the lifting equipment
must guarantee proper weight distribution.
If the apparatus is unloaded in the warehouse or in
the installation room, the area must be at least 3 x 2
m wide with another area at the same level. See par.
for handling. Small differences in level can be
compensated with temporary structures made using
wooden boards.
Unloading must be carried out with the utmost care
using suitable lifting equipment for the weight of each
unit group, especially in the presence of energised
overhead lines.
5.2 Control on receipt
WARNING
Do not put stress on the insulating parts while
handling the cubicles.
Before performing any operation, make sure that
the operating device springs are discharged and
that the apparatus is in the open position.
On receipt, immediately check the packing and
apparatus conditions.
Open the packing as shown in par. , handling with
care, and check that no damage has occurred during
transport and make sure that the nameplate
data(Figure 47) correspond to those listed in the ABB
order acknowledgement and on the freight bill.
Should any damage or imperfection in the supply be
noticed, report this immediately to ABB (directly or
thorough the agent or the supplier) and to the carrier
who delivered the goods. Notification of any possible
irregularity, even after receipt, must indicate the
switchgear construction year and the relevant order
acknowledgement number, which are indicated on the
switchgear nameplate.
The switchgear is supplied complete with the
accessories as specified in the order form and
confirmed in the order acknowledgement sent by ABB.
The documents enclosed in the packing are:
adhesive labels showing the addresses and
product type
this instruction manual
the test report
the electrical diagram
Note: For identification of substation one nameplate is
located on the cable cover of the first unit on the left
side.
5.2.1. Switchgear nameplate
Note: Each panel is fitted with one switchgear
nameplate which is located on the upper left side of
front panel.
