摘要： An object is to provide a crosslinkable resin composition which does not easily cause an increase in the pressure and a discharge variation in an extruder charged with the crosslinkable resin composition, with which an insulating coating layer can be continuously and stably formed by extrusion molding for a long time, thereby realizing an increase in the production unit of an electric wire/cable.
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).
