Construction of a Twin Installation with Two Rotating Phase Shifters
Construction of a Twin Installation with Two Rotating Phase Shifters
For our clients Kraftanlagen Energies & Services and Amprion, we delivered the construction of a complex twin installation. Rotating phase shifters are specialized machines that help stabilize the power grid by regulating voltage and power flow.
The project included extensive earthworks, concrete and reinforced‑concrete works, as well as the installation of drainage systems and asphalt surfaces. With approximately 16,000 m³ of excavation, a high‑quality façade, and large‑scale asphalt works, the facility was completed on schedule.
