Bushing unpacking
Unpacking operation and the subsequent activities must be performed in a clean and controlled environment
ambient. A closed and confined area with a concrete floor and adequate lifting facilities is necessary for all the
preparation operation.

wooden supports and it is locked by locking belts. Additional intermediate belts support the composite insulator

The transport box can be lifted by a suitable crane.
After the opening of the crate, the visual inspection of the bushing and the removal of the locking ropes and
locking blocks, the bushing can be lifted.
For this purpose lifting hooks are placed on the central and on both the side flanges, see
Figure 6
for some
typical arrangements.
Lifting operation must be performed by qualified operators, by using adequate synthetic lifting ropes and
cranes.
