High-tension electric cable comprising a metal sheathing; an inner coaial current-conducting core; a main insulation of compressed gas filling the space between the core and the sheathing; spaced toroidal supporting insulators for centering the core and having therein semicircular grooves in the areas of contact with the core and with the sheathing; the grooves having shielding electrodes therein which have contact with the core and with the sheathing; the generatrix of the side surfaces of the insulators coinciding with the electrostatic line of force of the cable, at any point of which the gradient of electrostatic potential is lower than the gradient on the surface of the core in the space or spaces between said insulator elements; the line of force, coinciding with the generatrix of the side surfaces, being so disposed in a longitudinal section of the cable that it begins on the surface of the core at a distance x = 1.1 r from the center of the semicircular section of the grooves which have the shielding electrodes, r being the radius of section of the grooves.
An improved high-tension cable employing an outer metal sheathing;
