Underground power lines

Expansion and reconstruction of transmission systems

The energy system transformation requires the construction of efficient power lines in North-South direction to distribute electricity, generated by wind turbines, throughout the entire German territory. Due to this distribution of energy a further adaption of connection lines is necessary. Regardless of this large transformation grids and hubs have also to be levelled.

Thereby, the underground construction with extensive civil and structural engineering activities becomes more important. With regard to this sector STREICHER looks back on longterm experience and carries out conventional laying methods (open and trenchless) as well as design and routing activities.

Scope of services

  • Execution of power lines of different voltage levels by means of modern laying techniques (e.g. HDD)
  • Border detection and routing
  • Assembly and connection techniques
  • Different measuring and inspection systems
  • Digital calibration and documentation
