Abstract

La présente invention concerne un dispositif de connexion de câble et un procédé de distribution d'énergie sans coupure et, plus spécifiquement, un dispositif de connexion de serre-câble ayant une fonction de levage isolante et un procédé de distribution d'énergie sans coupure à fil sous tension indirect utilisant le dispositif. Le procédé de distribution d'énergie sans coupure permet à un serre-câble de construction d'être remorqué et soulevé par une opération mécanique provoquée par une faible force d'un électricien en fil sous tension, contrairement à un procédé de distribution d'énergie sans coupure classique dans lequel, jusqu'à présent, un serre-câble de construction lourd était connecté et retiré en se basant sur la résistance physique d'un électricien en fil sous tension ; et, à la différence d'un processus, dans le procédé classique, dans lequel un support de câble temporaire est disposé séparément de façon à permettre à un câble de construction d'être monté et ensuite d'être à nouveau connecté à un fil électrique extra-haute tension, il permet à un serre-câble d'être monté, avec une courroie de remorquage isolante, dans le dispositif de connexion de serre-câble ayant une fonction de levage isolante, sans utiliser de support de câble temporaire et permet au serre-câble de construction d'être immédiatement et directement connecté à une ligne électrique extra-haute tension dans l'état de montage dans un processus requis, ce qui simplifie un processus de travail de façon à réduire le temps de travail, permettant une connexion électrique plus complète du serre-câble de construction par l'intermédiaire d'une simple opération mécanique plutôt que de se baser sur la résistance physique de l'électricien en fil sous tension, et réduisant de manière remarquable la charge de travail d'un ouvrier, etc., de telle sorte que l'utilisation sur site, la faisabilité économique et la sécurité peuvent être augmentées.
