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.

In one example, a cover plate may include a face plate with at least one outlet aperture, a back plate abutting the back of the face plate, an electric load between the face plate and the back plate, and at least one prong that extends from the face plate to a free end. The prong may be configured to interface with a terminal on the side of an outlet receptacle body and may include any or all of the following: an insulated portion and/or an electrical contact. The prong may resiliently deflects outward when interfacing with the terminal and may deflect with a first resistance prior to contacting a wall and with a second resistance that is greater than the first resistance when the prong contacts the wall. The cover play may also include at least one conductor electrically connecting the prong to the electric load.

Devices, systems, and methods for dissipating heat from electrical distribution assemblies and electrical switching devices are described herein. In one non-limiting embodiment, a dielectric material of relatively high thermal conductivity can be thermally coupled to electrical switching devices to act as a dielectric heat transfer window that dissipates heat. The dielectric heat transfer window includes at least a first portion thermally coupled to a heat generating component within an electrical switching device, and a second portion disposed external to the electrical distribution assembly or electrical switching device. Among other benefits, this allows heat generated within the electrical switching device to escape the interior of the electrical switching device to an environment external to the electrical switching device.

A power distribution box configured to house a plurality of electronic components is provided. The electronic components are mounted to a lower case. An upper case is mounted to the lower case and spaced apart from the lower case so as to define a storage compartment. The upper case includes a vent configured to allow heat generated by electric components to escape. In particular, the vents are registered so as to be above selective heat generating electric components.
