27 Jun We continue to advance as Technical Works Supervision
As Technical Works supervisors we continue to advance in IM3, in expansion of Nueva Valdivia 220 kV power substation project, owned by @Transelec, which consists of the following steps:
➡ The first consists of the installation of a 220/23 kV, 60 MVA power transformer, with its respective connecting bays at both voltage levels, and the construction of a 23 kV switchyard with a busbar sized for at least 8 feeders and their underground outgoing. This stage contemplates leaving the space for a future second 23 kV busbar with the same characteristics.
➡ The second stage consists of the construction of a 66 kV switchyard in a main and transfer busbars configuration, with space for at least 5 additional bays, the installation of a 220/66 kV, 60 MVA power transformer with their respective connection bays at both voltage levels, and the underground outgoing of a 66 kV line. The new transformation equipment cannot share the same bay in the 220 kV breaker-and-a-half switchyard, thus connecting through the incorporation of two additional half-bays.
The work carried out at the Nueva Valdivia power Substation is located more than 800 km south of the Metropolitan Region of Chile, in the Los Ríos Region with a rainy climate.
