<p>A method for providing an insulated electric high voltage DC cable or a high voltage DC termination or joint comprises the steps of providing (21) a polymer based insulation system comprising a compounded polymer composition (12); and subsequently exposing (25) the polymer based insulation system to a heat treatment procedure while the outer surface of the polymer based insulation system is covered (24) by a cover impermeable to a substance present in the polymer based insulation system in a non-homogenous distribution, thereby equalizing the concentration of the substance in the polymer based insulation system.</p> |
