Abstract (en)

[origin: WO2009103696A1] The high-voltage insulator contains a metal armature (2), an insulating tube (1) which is joined to the metal armature and is adhesively bonded to the metal armature at an end in the form of a bearing ring (10), and an axially symmetrical adhesive-bonding joint which is guided around the axis (A) of the insulating tube. An annular groove (23) which is guided around the axis of the insulating tube and receives an end section of the bearing ring is formed in the metal armature. A respective sealing surface (24, 13) is formed in the groove (23) and in the bearing ring (10). The two sealing surfaces are arranged and formed in such a manner that they slide on one another when joining the insulating tube (1) and the metal armature (2) so as to form a seal, and the bearing ring (10) which acts as a displacement body presses adhesive (32), which has been introduced into the groove (23), into the adhesive-bonding joint before joining. The insulator and a cooling element containing this insulator are simple to produce and are distinguished by a leakage rate of less than 10-9 [bar l/s] and by great operational reliability even after many years of operation with a large mechanical, electrical, thermal and chemical load.
