CABLE IMPREGNATING COMPOUND Russian patent published in 2005 - IPC

Abstract RU 2263360 C1

FIELD: electrical engineering; impregnating compounds for paper insulation of power cables.

SUBSTANCE: proposed impregnating compound has 73 - 77 mass percent of petroleum oil and 23 - 27 mass percent of thickening agent; used as the latter is product of thermal copolymerization of C₈ - C₉ fraction of liquid hydrocarbon pyrolysis. This impregnated compound is characterized in high rheological(viscous) characteristics and high insulating properties retained upon aging in catalyst (copper) environment.

EFFECT: facilitated manufacture, enhanced insulating properties as well as oxidation and aging resistance.
