Abstract
The end flange (16) of the first encasing part (10) of the gas-insulated high-tension installation is an outer flange and includes through bores (34). A first securing ring (18) is provided on the end-face side of the end flange (16). The securing ring holds a first insulator (28). The first securing ring (18) includes through bores (36) which are in alignment with the through bores (34) and which have a stepped configuration. The step forms, in each instance, a counterabutment (42), which cooperates with the abutment (44) of the respective threaded bolt (38). To secure the first securing ring (18) on the first encasing part (10), the abutment (44) rests on the counterabutment (42) and, on the other side, the threaded bolt (38) is supported by the nut (48) on the end flange (16). To secure the assembly (52) on the second securing ring (20) secured to the second encasing part (12), the nut ( 48) is released, the threaded bolt (38) is screwed, by its thread (46), into the threaded bore (36') of the second securing ring (20) and then the nut (48) is tightened again.
