Transmission system expansion along the highways

Transmission system expansion along the highways

The Energy Technology Society VDE Industry Association proposes to use increased highway and rail routes in order to lay new power lines.

"The discussion is currently limited to one side to the question whether one should simply replace overhead lines with underground cables, which is not always technically possible," the chairman of the company said in an interview with Jochen Kreusel Technology Review. "We pledge to join the infrastructure to alleviate the concern of citizens. These include highways, railways, rivers, canals and pipelines. Until now, any infrastructure planned for himself." Along existing or newly constructed lines, a system of walk-in tunnels or tubes to be built, in which one could, for example, install electricity and telecommunications cables.

Cheap this solution would not, but it could minimize the political opposition, which at the moment in Germany slows the expansion of electricity networks formed everywhere, there is resistance against the approximately 3,600 kilometers of power lines, which by 2020 must be built between coastal and alpine as the German have calculated Energy Agency (dena) and the power company in late 2010 released their Grid Study II. A preliminary analysis of 2005 had already shown a need of 850 kilometers were completed of which 100 km still miserable.

The favored solution of many citizens' initiatives, the underground cables are not as free of side effects, such as the activists are the hope. Be defeated because of the depth of two meters in pipelines must be buried a 40-meter-wide swath through the landscape. Once the work is a path 15-35 feet visible. This tape may not grow trees whose roots may damage the cable. Poles need not land lines, but no above-ground structures are not from them, too. For transport, the cable that is wound on reels and loaded onto a truck that can carry up to 800 meters of cable. The individual cable sections are connected by joints so that will be housed in garage-sized containers. Every 30 to 50 kilometers are also known as reactive power compensation devices to maintain the voltage at a constant value.
