Abstract: The crosslinked polyethylene composition according to the present invention is characterized in that the migration of additives is inhibited due to low oil content of low density polyethylene, and thus, when preparing crosslinked polyethylene using the same, stable extrusion property is exhibited, thus reducing exterior deviation of the crosslinked polyethylene.

Abstract: Disclosed is a crosslinked polyethylene resin composition. According to the present disclosure, a crosslinked polyethylene resin composition having general allowance temperature due to excellent heat resistance characteristics, enhanced long-term workability due to superior long-term aging resistance, and water tree inhibition effects similar or better than those of conventional crosslinked polyethylene (XLPE)), and a power cable manufactured from the composition may be provided.

Abstract: A cross-linked polyethylene composition for a power cable insulator including (A) 100 parts by weight of a polyethylene base resin, (B) 0.1 to 0.6 parts by weight of a hindered phenol-based antioxidant, (C) 1 to 4 parts by weight of a crosslinking agent, (D) 0.2 to 1.0 parts by weight of magnesium oxide and (E) 0.1 to 1.0 parts by weight of a scorch inhibitor, which advantageously exhibits superior resistance to water tree generated when a power cable insulator is exposed to outside water and electric field, and superior electrical insulation characteristics.
