Local Content
Marine and Oil & Gas industries demands higher local content rate at equipment
to be installed in oil rigs and offshore support vessels.
Looking in this direction, WEG support the customers to achieve the requested
local content rate by supplying products with high level of nationalization.
Using a completely national workforce and with the main component parts of
these alternators manufactured at WEG, the AN10 line of alternators reaches high
levels of local content.

WEG Original
Parts and Pieces
After years in operation, in addition to the periodic checkups
described in the maintenance plan, the alternators need
restoration in order to keep working properly.
For this restoration, we recommend that you use original
spare parts supplied by the manufacturer.
WEG team is available to promptly assist you in the correct
identification of the component parts.
