Summary: | The invention is related to a method of providing an insulated electric DC cable or DC termination or joint, the method comprising:-providing a polymer based insulation system (11,12,13) comprising a compounded polymer composition (12), characterized by the step of:-exposing the polymer based insulation system (11,12,13) to a heat treatment procedure while the outer surface of the polymer based insulation system (11,12,13) is covered by a cover (14) permeable to all the substances present in the polymer based insulation system (11,12,13) in a non-homogenous distribution, the permeable cover (14) having a melting and/or softening temperature greater than or equal to 120° C., thereby equalizing the concentration of the substances in the polymer based insulation system (11,12,13), the cable comprising a multi-wire conductor (10) that includes a central circular wire (101) that is surrounded by several layers of adjacent quadrangular wires (102). |
