Abstract

1395221 Gas filled cables GOSUDARSTVENNY NAUCHNO-ISSLEDOVATELSKY ENERGETICHESKY INSTITUT IMENI G M KRZHIZHANOVSKOGO 1 Aug 1972 35839/72 Heading H1A [Also in Division H2] A high tension coaxial compressed gas filled (e.g. nitrogen, sulphur, hexofluoride) cable comprises a conducting core 1, and enclosing metal sheath 2 and is provided with supporting toroidal insulator elements 3 of insulating material, e.g. porcelain, epoxy compound, ceramics, each of which is provided with circular grooves 4 which may have metal deposited thereon or be filled with metal to form electrodes 5. The grooves may be on the insulator surface disposed against the sheath 2 and cable 1, Fig. 1 (and Fig. 2, not shown) or only against the core surface, (Figs. 3 and 4, not shown). To maintain the voltage gradient at the insulator surface below the voltage gradient in the space 6 the lateral surface of insulator 3 is shaped according to a formula disclosed. In other embodiments (Figs. 2 3, 4, not shown) the groove space may be filled with an insulator (7).
