FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, namely to transmission of electric energy via high-voltage cables with gas, liquid or vacuum insulation. High-voltage cable containing a metal sheath with a gas, liquid or vacuum insulating medium and the inner conductor coated with a semiconductor or dielectric material, insulating extensions of rod type with lugs, contains at least two internal hollow conductors filled with gas, liquid or vacuum insulating medium, which are fixed on intermediate holders made of insulating material, centered relative to the shell using insulating stretch marks.
EFFECT: technical result is an increase in electrical strength and a decrease in the electrical capacity of the cable insulation while simplifying its design and installation.
