Abstract
The support insulator for a flexible gas-insulated transmission line is formed in two halves which can be snapped together and over the central conductor of the transmission line. The insulator halves each contain a central hub region and an outer rim region which are connected to one another by a thin connecting web of uniform thickness. The thin connecting web has axially offset regions which are connected to one another by axially extending side regions. Each of the axially offset regions has a generally pie or wedge shape and substantially increase the stiffness modulus of the insulator structure.
Claims11
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 at least first and second identical segments which fit over the central conductor of a transmission line and define a continuous disk therearound;
- each of said segments having a central axially extending rim for gripping a central conductor and an axially extending outer rim for gripping the interior of an outer housing;
- each of said segments having a central web extending between said outer rim and said central rim;
- and means for securing said at least first and second segments to one another to define a continuous support disk;
- said central web for each of said segments having at least first and second flat sections each extending between said central rim and said outer rim;
- and being displaced relative to one another in the direction of the axis of said disk, thereby to increase the stiffness modulus of said central web.
