Abstract An encapsulated gas-insulated high-voltage line for three-phase alternating-current energy transmission which is of the type incorporating a plurality of assembled longitudinal elements for each phase. Each such longitudinal element possesses an internally arranged conductor surrounded by a substantially tubular jacket formed of an insulator and filled with an insulating gas. Further, insulating support means serve to secure the internally arranged conductor within each associated tubular jacket. A ground wire is arranged parallel to the aforesaid longitudinal elements along the entire length of the high-voltage line. The invention further contemplates that at least one lining means formed of electrically conductive material and enclosed by an insulating material is embedded in the entire wall of each tubular jacket, this lining means being galvanically connected at least at one location with the ground wire.
