Nya isolationsmaterial för nästa generation av HVDC-kabel
Research Project , 2012 – 2015

The important goal of this project to provide concepts for novel insulation materials for high-voltage direct current (HVDC) cables that allows a more efficient long-distance transmission of electric energy from distant and carbon dioxide neutral energy sources (solar, wind and hydro) driven by the demands of a cost-effective and environmentally responsible power solution. The HVDC cable solution is the most feasible in view of geography (transmission across sea is required) and the unfeasibility to expand the overhead transmission network in Europe. The operating voltage has to be increased from todays 320 to 800 kV keeping todays cable geometry unchanged to meet the demands. From a Swedish industrial perspective such a major step would be of enormous importance. ABB and Borealis are world-leading companies in the involved branches. We are a group of scientists (chemists, material scientists, physicists and electrical engineers) that are approaching this difficult problem based on earlier own observations and indications reported in the scientific literature. Six different approaches are suggested, based on nanotechnology, tailoring the giant internal surfaces of polymer nanocomposites with functional groups to enhance stability towards high-energy electrons and other reactive species and also by promoting self-healing of flaws. The success of this project albeit having a clear technical goal require a strong scientific development of each of the included discipline areas.
