Transmission line design

Studio Pietrangeli has been working in the field of transmission line design for more than 30 years.

Over 7000 km of transmission lines projects

Our transmission line design concerns high voltage from 132 to 500 kV. In our transmission line design we carefully select the grid points to connect, the voltage level, the reliability of the line route and its interferences with the protected natural area, the peak load requirement of the interconnection (eventually in accordance with the related HPP production), in line with the national grid code issues. We usually identify more than one feasible scheme or route and evaluate an indicative cost estimate. We pay special attention to capabilities and harmonization with the existing transmission facilities, minimization of power losses and reactive power issues.
