Abstract: An insulator (100) for installation in a high-voltage switching system is described. The insulator (100) includes an electrically insulating disc-shaped carrier element (110), wherein the carrier element (110) has a first disc-shaped surface (111) including a first groove (121) configured for accommodating a first sealing element (131) and an opposing second disc-shaped surface (112) including a second groove (122) configured for accommodating a second sealing element (132), wherein at least a bottom of the first groove (121) is provided by a first metallic element (141) embedded in the carrier element (110), and wherein at least a bottom of the second groove (122) is provided by a second metallic element (142) embedded in the carrier element (110).

Abstract: The invention relates to an insulation assembly (1,1') for gas-insulated electric apparatus and a specially to the insulation assembly (1) which is constructed as an insulator body (2) inserted between connecting flanges (5,6) of the gas -insulated switching installation where the flanges (5,6) are closed by an outer metal ring (7) closing the insulating chamber (4) filled with an insulating has (8) or to the insulation assembly (1') having a cover (11) closing the insulating chamber (4') filled with an insulating has (8). The use of the insulation assembly is characterized in that the gas seal (9) has an O-ring or X-ring type shape and consists of seal core (9a) covered with a coating (9b) and the seal core ring (9a) is made from different material than the coating (9b).
