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.

A cable accessory device (2) comprises an outer body (6) having a first side (8), a second side (10), and an interior space (12); a stress controlling element (14), and an inner layer (28). At least the first side (8) is configured to feed an end of a high voltage cable (4) into the interior space (12). The stress controlling element (14) is configured to be arranged on the cable (4). The inner layer (28) is configured to be arranged around the cable (4) under tension. At least one pressure alleviating component (20) having a first end (24) and a second end (26) is configured to be placed around the cable (4) at the stress controlling element (14) or the inner layer (28) to exert a radially inwards directed force onto the cable (4), the force decreasing from the first end (24) to the second end (26).

A cable gland system for an armored cable is disclosed. The system may include a housing, a first insulating layer, a second insulating layer and an elastomer gland. The housing may include a first portion and a second portion. The first insulating layer may be disposed in the first portion, and the second insulating layer may be disposed in the second portion. The elastomer gland may be disposed in the housing between the first insulating layer and the second insulating layer. The first insulating layer, the elastomer gland and the second insulating layer may receive a unified insulated conductor of the armored cable. Further, the elastomer gland may secure the unified insulated conductor via an interference fit in an elastomer gland interior portion.
