In an arrangement for connecting a high-voltage or very-high-voltage power cable comprising an insulative external jacket to an equipment element comprising an external surface by means of an insulative layer, the insulative layer consists of a composite material resistant to traction in the longitudinal direction of the cable and attached to said external jacket and to the external surface.

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 cover assembly for covering an elongate substrate includes a resilient, elastically expandable sleeve member and a holdout device. The sleeve member defines an axially extending inner sleeve passage. The holdout device includes a generally tubular, flexible bladder sleeve mounted in the inner sleeve passage. The bladder sleeve defines a cavity and a holdout passage to receive the elongate substrate. The cavity is inflated or inflatable with an inflation gas.

An insulation termination assembly comprises an insulation tube, an annular bottom plate, and a tail assembly. The insulation tube has an inlet end, an outlet end opposite to the inlet end, and an inner space filled with an insulation liquid. The annular bottom plate is mounted at the inlet end of the insulation tube. The tail assembly comprises an insulation connection tube mounted on the annular bottom plate and a shield tail tube connected to the insulation connection tube. A cable joint of a cable is introduced into the inner space of the insulation tube from the inlet end of the insulation tube after passing through the shield tail tube and the insulation connection tube.
