Abstract

Foreliggende oppfinnelse vedrører elektrisk isolerende oljebaserte sammensetninger omfattende mineraloljer og oljeløselig syntetisk blokk-kopolymer av polystyren og syntetisk gummi med en molekylvekt fra 50.000-1.000.000. Oljekomponenten har fortrinnsvis et innhold av aromater på 5-30 vekt%. Forbindelsen har høy viskositet ved lav temperatur og er en tynn væske ved 40-80°C. Gassabsorpsjonskapasiteten til sammensetningen er høy og de er spesielt anvendelige som isolasjonskomponent i papirviklede kabler som høy- spenningskraftkabler for likestrøm (HVDC).The present invention relates to electrically insulating oil-based compositions comprising mineral oils and oil-soluble synthetic block copolymers of polystyrene and synthetic rubber having a molecular weight of 50,000-1,000,000. The oil component preferably has a content of aromatics of 5-30% by weight. The compound has high viscosity at low temperature and is a thin liquid at 40-80 ° C. The gas absorption capacity of the composition is high and they are particularly useful as an insulation component in paper-wrapped cables such as high voltage direct current (HVDC) cables.
