Abstract
An insulator disk for supporting a flexible conductor within a flexible gas-filled outer housing consists of three identical segments which latch together to form a complete disk around the central flexible conductor of the flexible cable. The outer peripheries of the three segments form a continuous outer periphery which is pressed into engagement with the interior surface of the grounded outer housing. Each of the identical segments has an extending latch at one of their outer surface ends and a latch receiving surface at the other of their outer surface ends, wherein the extending latch of one segment latches into the latch-receiving segment of an adjacent segment.
Claims18
An insulator support disk for supporting the central conductor of a gas-insulated transmission line within an outer grounded housing which is coextensive with said central conductor;
- said insulator support disk consisting of a plurality of identical pie-shaped segments, each extending over an angle less than 180.degree. around said central conductor, and each having a central axial extending rim for gripping the central conductor of a transmission line, an axially extending outer rim for gripping the interior of the housing of a transmission line, and a central web extending between said outer rim and said central rim, and means for securing said plurality of segments to one another to define a continuous support disk.
