Abstract
High voltage electrical cable comprising an inner elongated conductive member, a corrugated metallic tubular member positioned about such inner member, and a plurality of nonconductive spacers each positioned along the longitudinal axis of the electrical cable and extending between said members through a nonconductive environment comprising, for example, a gaseous, foam or liquid insulator. To avoid premature insulation breakdown or sparkover in the vicinity of the spacers, such spacers are so configurated and positioned that their end portions coming into engagement with the corrugations of the surrounding tubular member follow the profile of the engaged corrugations so as to extend into the corrugation troughs thereof.
