cgm.3 system
Fully SF6 gas insulated medium voltage switchgear up to 40.5 kV in accordance with IEC Standards
2 Handling and transport
Important: During transport, the switchgear
must be perfectly seated and xed so that it
cannot move about and possibly damage the
equipment.
2.1 Lifting means
The switchgear must always be kept upright, directly
on the ground or on a pallet depending on the type of
handling involved.
To handle assemblies of up to 4 cgm.3 functional units,
one of the following methods must be used:
1. Using a forklift truck or pallet-jack
[5]
.
Figure 2.1 Lifting a cgm.3 modular cubicle using a fork-lift
truck.
2. Lifting using slings or chains fixed to the lifting
supports on the sides of the top of the cubicle. The
angle of pull should be as vertical as possible (with an
angle greater than 60º from the horizontal).
Figure 2.2 Lifting a cgm.3 modular cubicle with chains.
3. If it is not possible to use the aforementioned methods,
rollers may be used underneath the switchgear.
Another option is to slide the cubicles over rods
(these same rods can be used to help get over the
cable trench).
4. To handle sets of 5 functional cgm.3 units (consisting
of either coupled modules or compact assemblies
associated with modules), use lifting systems (slings,
lifting beam, etc.) with a pull angle greater than
65º and less than 115º in order to prevent possible
damage to the cubicles during hoisting.
[5]
Position the rear of the cubicle facing the driver, to avoid damaging the front.
