A power cable termination device for a high voltage direct current gas-insulated switchgear including: an outer housing made of an electrically conducting material, connectable to the switchgear; a terminal portion of a power cable, the power cable including an electrical conductor, a circumferential electrically insulating layer, and a circumferential conductive shield which is stripped off along a first part of the power cable; an electric field grading system including a resistive field grading material layer arranged circumferentially around the power cable to axially cover the edge of the conductive shield where the conductive shield is terminated, the resistive field grading material layer being in electrical contact therewith, and a connection device connectable to the gas-insulated switchgear and arranged to provide mechanical support and electrical contact with the gas-insulated switchgear.

Power cable termination device for gas-insulated switchgear

A method for determining conductivity of cable insulation of a cable including at least one conductor that determines the central axis of the cable and insulation layer surrounding the conductor longitudinally and radially includes steps of retrieving a cable sample from a cable, which sample includes a length of at least one insulation layer and preparing an insulation sample from the cable sample. The insulation sample is prepared from cable sample by cutting a circular layer having a set thickness at desired radius from the central axis of the cable.
