In the context of the continuous development of renewable energy, the cable trench execution project in the Vifor Wind Farm - one of the implementation phases - represents a significant step toward ensuring a modern and efficient infrastructure.
Located in Luciu Commune, Pogoanele Town, Buzău County, Romania, this project was carried out during May–June 2025. The purpose of this article is to provide a detailed overview of the work performed, aimed at specialists in the solar and wind energy sectors as well as professionals interested in best practices for electrical energy infrastructure.
Execution of electric cable trenches
Works for the medium-voltage electric power collection network began with the precise marking of trench routes according to the execution plans.
Excavation was done mechanically, adapted to each circuit width - from 0.60 m to 3.30 m. In total, over 27,000 linear meters of trenches were dug, with depths in compliance with mechanical and electrical protection standards.
This stage is crucial to ensure a solid and secure foundation for the electrical infrastructure.
Trench measurements
An important aspect of this project was the accurate determination of trench lengths. The table below shows the trench widths and total lengths:
| Trench Width | Total Length | Unit |
|---|---|---|
| 0.60 m | 13,383.0 m | m |
| 0.80 m | 6,316.0 m | m |
| 1.10 m | 1,032.0 m | m |
| 2.10 m | 2,454.0 m | m |
| 2.70 m | 2,156.0 m | m |
| 3.30 m | 1,929.0 m | m |
| 0.60 m (under roads) | 350.0 m | m |
Laying of cables and protective conduits
| Underpass Type | Total Length | Unit |
|---|---|---|
| Directional drilling (under canals) | 965 m | m |
| Directional drilling (under roads) | 60 m | m |
