Abstract: A method is provided for applying a field grading layer to a power cable includes preparing a polymer composition having a polymer matrix, at least one conductive filler different from a non-linear conductive organic filler, and at least one crosslinking agent. The method includes extruding the polymer composition into a crosslinkable field grading tape and winding the crosslinkable field grading tape onto a section of power cable in need of field grading. The crosslinkable tape is crosslinked to obtain a field grading layer.

Abstract: A method for preparing an HVDC cable for jointing or termination includes the step of providing a section of an HVDC cable comprising a conductor surrounded by a first semiconducting layer, and at least one insulation layer of a first polymer material surrounding the first semiconducting layer, where the insulation layer comprises conductive volatile by-products. A tape of a second polymer material is provided, where the additional layer comprises conductive volatile by-products. The tape is lapped onto the insulation layer thereby forming an additional layer. Heat is applied to crosslink the additional layer and redistribute the conductive volatile by-products.
