Abstract (en)

[origin: EP1873804A2] The method involves placing expanders (19-21, 26,27) between dielectric shields (11-13), and a cylindrical enclosure (1) of an electrical device e.g. vacuum bulb. The expanders exert efforts on the shields and the enclosure to position the shields with respect to the enclosure and/or locking the shields in position with respect to the enclosure by friction between the expanders and the shields, and the expanders and the shields. The expanders position and/or maintain the shields with respect to the enclosure, by welds between the shields and the expanders, and the expanders and the enclosure. Independent claims are also included for the following: (1) an electrical device comprising an element fixed on a part of the device by using an electrical device`s part fixing method (2) a vacuum bulb comprising an element fixed on a part of the device by using an electrical device`s part fixing method.
