Abrégé
(EN)
The invention discloses a gas-insulated and metal-enclosed power transmission line comprising a number of pipeline units, wherein each pipeline unit comprises a shell body, flange plates positioned on two ends of the shell body, a conductor positioned in the shell body, an insulating support column positioned in the shell body and used for supporting the conductor and insulating compressed gas placed between the shell body and the conductor; a sealing ring adhered to outer annular surfaces and inner walls of the shell bodies is arranged between two neighboring shell bodies, two ends of the sealing ring are provided with clamping bars which protrude beyond the outer annular surfaces, and clamping grooves that are matched with the two clamping bars are arranged between the two neighboring shell bodies. Via use of the sealing ring, air-tightness between the two neighboring pipeline units can be effectively improved.
