SüdOstLink: Construction progress in Bördeland visible!

The construction of the SüdOstLink in the Salzland district is making great strides, and that is pleasing to everyone who is counting on tomorrow's electricity supply. The section between Welsleben, Biere and Eickendorf is currently being intensively worked on. Loud People's voice The experts at the transmission system operator 50Hertz have made impressive progress in the last few months. Around 3.8 kilometers of the 7.8 kilometer long route in the municipality of Bördeland are now equipped with cable protection pipes and the trenches have already been backfilled. Cable pulling is in full swing, which is a good sign that it will be completed soon.

A crucial aspect of the SüdOstLink is the technology behind it. With two line connections, each capable of transporting an output of 2,000 megawatts, this corresponds to around 1,400 wind turbines at full load. Each of these connections uses two plastic-insulated underground cables that are rated for a voltage of 525 kilovolts. Modern high-voltage direct current (HVDC) transmission systems are used, which are loud 50Hertz enable low-loss and targeted transport over long distances.

Technical details and advantages of HVDC

The use of HVDC technology brings with it several advantages. This technology only requires two conductors instead of the usual three and therefore enables a lower loss rate than conventional three-phase cables. Converters are required at both ends of the HVDC link to convert alternating current into direct current and vice versa. This is important to ensure stable network management, especially when it comes to integrating renewable energies. A corresponding power converter will be installed at the Wolmirstedt substation in order to make optimal use of the technology, explains BfS.

Another advantage of this design is the way electric fields and associated magnetic fields work. Weak magnetic fields occur near HVDC lines and do not pose any health risks, explains the BfS. These fields are comparable to the earth's natural magnetic field. The use of underground cables also ensures that the electrical fields are shielded, so that no significant disturbances can be expected on the earth's surface.

Environmental and health effects

Of course, environmental protection also plays a major role in such large-scale projects. The construction of HVDC systems is carried out under strict legal frameworks that take potential health effects into account. According to the BfS For example, limit values ​​for static and low-frequency fields are set in order to protect both people and animals.

Overall, it is clear that the SüdOstLink is a promising project that not only ensures the stability of the power supply, but also serves as an example of the integration of modern technologies and environmentally conscious construction. The progress in the past few months is a good indication that the project is about to be successfully completed.
