Abstract
A gas-insulated high-tension three-phase electricity line which includes a cylindrical steel case and three conductors disposed parallel to the axis of the case, and a magnetic screen constituted by a cylindrical aluminum case placed inside the steel case and very close thereto. The conductors are held by a plurality of sets of three insulating arms secured to one another, the conductors being free to slide through openings formed in the arms, the aluminum case being separated from the steel case by strips of plastics material or of filled polymer having a low coefficient of friction.
