Novel crosslinked polymer composition, power cable insulation and power cable

摘要

PROBLEM TO BE SOLVED: To provide a crosslinked polymer composition, a power cable insulation and a power cable which are particularly useful in a high voltage direct current (HVDC) application and an ultra high voltage direct current (EHVDC) application. A cross-linked polymer composition obtained by cross-linking a polymer composition comprising a polyolefin, a peroxide and a sulfur-containing antioxidant, wherein the cross-linked polymer composition has a Z content. And a peroxide by-product in an amount corresponding to Wppm, wherein Z
