Abstract

A polymer composition includes a crosslinked polyolefin with improved DC electrical properties. Prior to crosslinking, the polymer composition includes a polyolefin and peroxide, in which the peroxide is in an amount of less than 35 mmol —O—O— per kilogram of the polymer composition. A cable can be surrounded by at least one layer including the polymer composition.
