In addition to the retrofitting of the Transformer, the scope also provided for the study, supply and installation of 12 high voltage insulators for connection in SF6, in other 04 machines

Restoring large equipment, with very unique characteristics, originally from another major manufacturer, and further improving the project, reinforces WEG's quality and high technical capacity. In addition to the repair of the three-phase elevator transformer, the service also involved the study, supply and installation of 12 high voltage bushings, on 04 machines from the same plant.

The performance of the service ensured greater operational security for Copel (Companhia Paranaense de Energia) and also for its users. The Governador José Richa Hydroelectric Plant, also known as the Salto Caxias power plant, located in the city of Capitão Leônidas Marques - PR, where the service was performed, is one of Copel's most important, with 1,240 MW of power.

WEG competed with other important players, including the original manufacturer.  Because of this large peice of equipment, with high voltage insulated with SF6 gas, the main differential in this supply was the ability of WEG to quickly develop a manufacturer alternative for such a high voltage bushings that met both technically and commercially, thus enabling the process of reforming the transformer.

The service package, provided by WEG, included the scope of the study, supply and installation in the field of 12 high voltage RIP SF6 bushings, in the four main transformers already installed; study, adaptation and supply of 03 new high voltage RIP SF6 bushings for the spare transformer; supply of 01 new spare high voltage bushing (RIP SF6); complete overhaul of the transformer, including complete rewinding, new high voltage outputs, studies and improvements in the cooling system, structural improvements in the tank and the main cover, alteration of the pressing system of the active part and supply of a new breech to the core.

In an extremely agile and coordinated process, the WEG team, made up of Engineering, Supplies and Services, made the necessary adaptations to replace the bushings in the field possible, valuing the operational condition as much as possible and reducing the changes in the set of original coil outputs, minimizing any impact on field activities.
