Abstract
(EN)
Devices forming a stiffly flexible framework, preferably formed of multiple lengths of stranded metal cable, are disclosed. These devices space conductors (such as those of transmission lines). Where stranded metal cable is used interstrand friction dampens vibrations in, and relative motion between, the conductors. Unlike conventional dampers, those described herein avoid the need to use both elastomeric bushes and internal bolts to dissipate vibration energy.
(FR)
Ces dispositifs sont formés à l'aide d'une structure flexible de façon rigide, réalisée préférablement à partir de plusieurs longueurs de câble métallique toronné, et servent à maintenir un certain espacement entre des conducteurs (tels que ceux utilisés dans les lignes de transmission). Aux endroits où l'on utilise un câble métallique toronné, la friction entre les brins du câble amortit les vibrations des conducteurs ainsi que le déplacement relatif entre ceux-ci. A la différence des dispositifs d'amortissement classiques, les dispositifs décrits ici ne nécessitent l'utilisation ni de traversées isolantes élastomères ni de boulons internes pour dissiper l'énergie vibratoire.
