Zusammenfassung:Provided is a cross-linked polyethylene composition, which is improved in dispersibility, a sweat-out phenomenon, and void occurrence and exhibits excellent electrical insulation properties. The cross-linked polyethylene composition comprises (A) 100 parts by weight of polyethylene, (B) 0.2-0.6 parts by weight of a mixture of a liquefied antioxidant of the following formula 1 and a hindered phenol- or thioester-based antioxidant, (C) 0.2-0.9 parts by weight of polyethylene glycol having a molecular weight of 5,000-70,000, and (D) 1-4 parts by weight of a cross-linking agent. The polyethylene has a density of 0.87-0.96g/cm^2, a melt index of 0.1-50g/10min, and a weight average molecular weight of 40,000-200,000.
