Program:
Moderator: Leif Asp, Co-Director Chalmers Area of Advance Materials Science
Development of Next Generation Insulation Materials for High Voltage Power Cables, Christian Müller, Professor at the Department of Chemistry and Chemical Engineering, Chalmers University of Technology.
High Voltage Power Cables Insulated with the Next Generation of Crosslinked Polyethylene, Per-Ola Hagstrand, Expert at Borealis Innovation Centre. Adjunct Professor at Applied Chemistry, Chalmers University of Technology
Per-Ola Hagstrand, Innovation & Technology, Borealis AB.
Polyolefin materials can and will play a vital role in the transition towards a more sustainable society. For example, Germany will use high voltage direct-current (HVDC) power cables insulated with next generation cross-linked low density polyethylene (XLPE) to transfer a vast amount of renewable energy from north to south with minimal losses. This will facilitate Germany’s green-energy transition (“Energiewende”). The presentation will give an overview of the development of next generation XLPE-based insulation material, which can be used up to a world record operating voltage of 640 kilovolt (kV).
Christian Müller, Chemistry and Chemical Engineering, Chalmers.
High-voltage direct-current (HVDC) cables are a critical component of tomorrow’s power grids that seamlessly integrate hydro, wind and solar power. This presentation will discuss academic research efforts that aim to develop new materials concepts for the next generation of HVDC cable insulation. In particular, new crosslinking concepts based on polyethylene copolymers, the use of thermoplastic polyolefin blends as well as additives that allow to reduce the electrical conductivity of the insulation material will be explored. Finally, the presentation will reflect on sustainability aspects, which play an increasing role in the development of new HVDC insulation materials.
