138 kV Link San Rafael - Ananea Derivation, extensions and associated substations (ITC Project)

Description: The project includes the construction of the following facilities: Construction of new San Rafael 138 kV Derivation substation. Expansion of the Ananea substation at the 138 kV and 60 kV levels to obtain 138/60 kV transformation capacity. 138 kV transmission line San Rafael – Ananea Derivation, double-stranded, 120 MVA design power and 104.7 km in total length. Connection link at 138 kV Derivación San Rafael – San Rafael, with a double triple and 1.43 km in length, which starts from the Derivación San Rafael substation to a sectioning point of the lines San Rafael – El Ángel (L-1051) and San Rafael – Azángaro (L-1009), with the same driver. Connection link at 138 kV San Rafael Derivation to the sectioning point of the lines San Gabán II - Azángaro (L-1010) and San Rafael to El Ángel (L-1051), of double triple and 0.56 km in length, which starts from the San Rafael Derivation substation to a sectioning point of the aforementioned lines L-1010/L-1051, with the same conductor. Connection link at 138 kV San Rafael Derivation to the sectioning point of the San Rafael – Azángaro lines (L-1009) and San Gabán II – Azángaro lines (L-1010), with double triples and 1.31 km in length, which starts from the San Rafael Derivation substation to a sectioning point of the aforementioned lines LT 1009/1010, with the same conductor. The project, located in the department of Puno, aims to improve the reliability of the transmission system in the area served at the 60 kV level by the Azángaro and Ananea substations of the Ananea Electric System. Likewise, operating conditions are improved at the 138 kV level, in the current 138 kV San Gabán II-San Rafael-Azángaro transmission axis.
