1. A device for transporting a medium, comprising:
a first potential equalization conductor:
an electrically conductive inner envelope configured to enclose a channel which extends in an axial direction for passage of a medium, said inner envelope being connected to the first potential equalization conductor;
an outer casing configured to be electrically conductive;
an electrically conductive second potential equalization conductor;
an electrically conductive outer envelope provided between the channel and the outer casino and connected to the second potential equalization conductor:
an electrically insulating intermediate layer arranged between the channel and the outer envelope and produced from heat-insulating material,
an end piece and an electrically conductive cap placed upon the end piece, and
an electrically conductive shrink tube applied to the electrically conductive cap and to at least one area of the outer casing to secure the cap and to electrically conductively connect the electrically conductive cap to the outer casing.
