  1. 1. Polyethylene Blends, a Material Concept for Future HVDC-cable Insulation

    Författare :Mattias Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer blends; nanocomposites; polyethylene; conductivity; thermomechanical properties; High-voltage insulation; tie-chain;

    Sammanfattning : High-voltage cables are a critical component of tomorrow’s power grids that seamlessly integrate hydro, wind and solar power. Further improvements in transmission capacity of both high-voltage alternating- and direct-current, HVAC and HVDC, cables are likely reached through improved insulation materials. LÄS MER
