Metallic sealing tube
2.5 Transport, storage and handling
The bushing may be transported and stored at any angle.
Carefully inspect the bushing when received with regard to
shipping damage. Please note that the bushing has been
routine tested in oil and some oil may remain. Vaseline is
used for lubrication of threads, and at some temperatures
the vaseline may appear as oil.
When removing the sealing tube, be careful not to damage
the tube gasket. The sealing tube, with the gasket, drying
agent and fasteners should be reassembled after the
transformer test at a torque 50 Nm.
The metallic sealing tube on the oil side, shown in
Fig. 5, must be mounted on the bushing during
long-term storage (>1 year).
Protect the bushing from water when stored
outdoors. The crate must not be stored at a location
where the ground can become wet and muddy
during heavy rain. Shelter the crate from rain and
snow with a tarpaulin or roofing.
