Abstract
There is provided an olefin resin composition for power cables which contains an olefin resin and m-(tert-butylperoxyisopropyl)-isopropylbenzene and/or p-(tert-butylperoxyisopropyl)-isopropylbenzene. A crosslinking agent of this resin composition is suitably used for at least one of layers including semiconductor layers and an insulation layer in the power cables or around conductors at a joint between the power cables, whereby the high-temperature properties of the power cables can be improved.
