132/33 kV power increase
Expand the capacity of a 132/33 kV infrastructure by integrating switching, protections, and new transformation outputs without compromising system reliability.
INELCO developed the assembly of 33 kV cells, the manufacturing of a gantry connected to three 30 MVA transformer outputs, and the undergrounding of medium-voltage circuits in 33 kV and 13 kV to support the system's power expansion.
The project was completed with the manufacturing of LVDPs for protection, monitoring, and commands, integrating RTUs and battery banks for supervision and service backup in switching and control.
A set of splices, terminal connectors, Cu tubular bars, connectors, and current and voltage measurement cabinets was also manufactured to complete the electrical connection with high availability criteria.
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.
