OLJEIMPREGNERAD STARKSTROMSKABEL

摘要

Provided is an oil-impregnated power cable comprising an insulation layer formed by winding a composite film of polyolefin film and insulating paper onto an electric conductor and impregnated with an impregnating oil, said impregnating oil comprising distillates within a boiling range in terms of values at normal pressure between 265 DEG C. and 360 DEG C. obtained by contacting a hydrocarbon mixture with a boiling range between 75 DEG C. and 198 DEG C. resulting from a thermal cracking of petroleum hydrocarbons at a temperature of 700 DEG C. or higher and containing monocyclic aromatics and aromatic olefins, in liquid phase with an acid catalyst.
