4.3.2 Oil-filling of the bushing for horizontal installation

Overview
• This procedure applies to bushings that will be oil-filled with an atmospheric process.
• This procedure does NOT apply when the bushing will be oil-filled with the vacuum process, refer to
Horizontal installation of the bushing on the transformer, page 24.
This procedure must be done immediately before installation of the bushing on the transformer, because there
is no expansion space for the oil after this procedure is completed. Thus, changes in the ambient temperature
will cause the oil to expand or contract, this will cause damage to the seals in the bushing.
CAUTION!
Do not leave the bushing fully filled with oil.
Installation must be done immediately after the bushing is sealed. If not, changes in the ambient
temperature will cause damage to the seals in the bushing.

CAUTION!
Make sure that the bushing does not rotate.
