A crosslinkable resin composition of the present invention contains 100 parts by mass of an ethylene-based resin (A), a stabilizer (B) containing 0.001 to 0.5 parts by mass of a hindered amine light stabilizer (B3), and 0.5 to 3.0 parts by mass of an organic peroxide (C). The hindered amine light stabilizer (B3) is a mixture of a low-molecular-weight hindered amine compound having a molecular weight of 100 to 1,000 and a high-molecular-weight hindered amine compound having a molecular weight of 1,500 to 5,000. The hindered amine light stabilizer (B3) has a reduced viscosity of 3.5 to 5.5 cm 3 /g (40°C) and a reduced viscosity of 2.0 to 3.5 cm 3 /g (110°C).

摘要： Provided is an insulating resin composition for a DC power cable, which insulating resin composition has excellent extrudability, is unlikely to experience sagging, has good scorch resistance, generates a smaller amount of secondary decomposition water, can form an insulating layer that stably exhibits good DC electrical properties, and has high extrusion stability. The insulating resin composition for a DC power cable according to the present invention includes (A) a low-density polyethylene having a complex viscosity η* 100 , which is measured at 130°C and a frequency of 100 rad/s, of 600 to 1,300 Pa·s, wherein a ratio (η* 0.1 /η* 100 ) of a complex viscosity η* 0.1 , which is measured at 130°C and a frequency of 0.1 rad/s, to the complex viscosity η* 100 is 4 or more; (B) a modified polyethylene; and (C) a stabilizer including a mixture of a hindered phenol antioxidant and a thioether antioxidant. The amount of carbonyl groups introduced into the resin composition through the component (B) is 7 × 10 -6 to 1.3 × 10 -5 mol/g relative to the total mass of the component (A), the component (B), and the component (C).
