Patent ID: 8366484

Claim:
A device for electric connection to an energy supply conductor for medium and/or high voltage comprising: a voltage-carrying element with an outer periphery; a tubular outer shell with an inner periphery, the tubular outer shell defining a longitudinal axis (x-x) and being formed by a polymer and connected to the voltage-carrying element, the voltage-carrying element extending in the axial direction of the outer shell, and along at least a part of the axial extension of the voltage-carrying element, the outer shell extends axially with a space between its inner periphery and the outer periphery of the voltage-carrying element, the outer shell being provided with an outer contact surface for connection to a wall of a container somewhere along said part of the axial extension of the voltage-carrying element, the outer shell is being adapted to separate the space from an atmosphere outside the container in which the device is connected, and at least along a section of said part of the axial extension of the voltage-carrying element the space is filled with a filler of an electrically insulating material other than that of the outer shell, the filler completely filling the space along said section; at least one guiding element for guiding the electric field produced by the voltage-carrying element, the guiding element being at least partly conductive and provided in said space, the guiding element being radially spaced from the inner periphery of the outer shell, providing a gap in the radial direction between the guiding element and the inner periphery of the outer shell, the gap being filled with the filler; and a plurality of support members are provided, each having a radial extension, and the support members are adapted to provide the gap between the guiding element and the inner periphery of the outer shell, such that the support members are integral with the guiding element.
