New construction of a solar park on the former air base
Pütnitz in Ribnitz-Damgarten - SOLAR WORLD AG

On the former air base in Pütnitz, the solar module manufacturer Solarworld AG installed a new solar power plant with 88,000 modules. To connect the power plant to the existing grid, crossing the Saaler Bodden proved to be the most effective route choice. For this purpose, the Bodden had to be crossed by horizontal directional drilling over a length of approx. 1,600 metres and at a depth of up to 30 metres. For the 6 high-voltage cables to be laid, 2 bundles of 3 protective pipes each were planned in two self-sufficient routes. Due to difficult ground conditions, it was decided to stabilise the drilled channels with one steel protection pipe each and to pull the actual cable protection pipes into them. High-temperature resistant, polymeric protective pipes of the Gerodur EMDS protective pipe system of the high-performance class LHT^® were chosen as direct protection for the 110kV cables, the time and cost advantages of which could already be used when laying the pipes. The protective function for high-voltage cables can be maintained over the full service life function. In addition, an intact protective conduit system is available even after the useful life of the installed cables has expired, which is adequate for a renewed move-in of new high-voltage cables.
