Transformer Substation + 33 kV Overhead Line
Develop a transformer substation with a 33 kV overhead line for plant supply, integrating the yard, medium-voltage switching, and line routing in a single project.
INELCO executed the assembly of the transformer substation and the 33 kV generation yard for the energy supply of a water injection plant, including the provision and assembly of Schneider 13 kV and ABB 33 kV disconnectors, measurement boxes, transformers, switchgear, and medium-voltage protections.
The scope also included the manufacturing, supply, and laying of low-voltage control and command cables from the shelter to the electrical yard, ensuring continuity between instrumentation, switching, and field operation.
Regarding the line front, 40 km of 33 kV mixed overhead line were built using Canadian suspensions, strain structures, and concrete poles, along with medium-voltage undergrounding, splices, terminal connectors, and the laying of shield wire with fiber optics to complete the associated infrastructure.
Medium Voltage Cell Replacement + 33 kV Underground Line
Renew medium-voltage cells and link a 33 kV underground line while minimizing critical interventions on the transformer substation.
INELCO executed the replacement of medium-voltage cells at the transformer substation with the latest Schneider line, incorporating the manufacturing of terminal connectors, laying of underground conductors between the yard and the cell room, manufacturing of gas exhaust ducts, and commissioning of the entire set.
The project was complemented by the assembly of 19 km of two 33 kV circuits from the transformer substation, the manufacturing of bases for concrete poles in overhead diversions, new terminal connectors, and the full commissioning of the underground link.
