Patent ID: 8134089

Claim:
A device for electric connection to an energy supply conductor for medium and high voltage, comprising: a voltage-carrying element, a tubular outer shell formed by a thermoplastic polymer and connected to the voltage-carrying element, wherein the voltage-carrying element extends in a longitudinal direction of said tubular shell, and wherein, at least along a part of the length of the voltage-carrying element, the outer shell extends in said longitudinal direction with a space between its inner periphery and an outer periphery of the voltage-carrying element, said outer shell being provided with an outer contact surface to be connected to a wall of a container somewhere along said part of the length of the voltage-carrying element, wherein said outer shell is arranged to separate said space from an atmosphere outside a container to which said device may be connected, characterised in that, at least along a section of said part of the length of the voltage-carrying element said space is filled with a solid or liquid filler of an electrically insulating material other than that of the outer shell, said filler completely filling said space along said section.
