Abstract

L'invention porte sur un manchon de sertissage (également dénommé étrier) utilisé avec une ligne de transmission et de distribution. Ledit manchon de sertissage comprend une base cylindrique et une plaque de couverture qui présentent toutes deux des sections transversales dont l'évasement est de 8, H ou C. La base et la plaque de couverture sont apposées de manière à former deux gorges de câble dont la configuration est un orifice passant, les deux gorges étant en contact avec le câble. Sur la surface interne et sur la surface externe de la base et de la plaque de couverture, sont pratiqués des évasement concaves et/ou convexes de verrouillage ou encore des gorges de verrouillage et/ou des cannelures de verrouillage dans l'alignement de points. Soumis à une pression, les gorges de verrouillage, les cannelures de verrouillage, les parties concaves de verrouillage et les parties convexes de verrouillage peuvent réduire la contrainte exercée sur des surfaces interne et externe de l'étrier et ce de manière efficace grâce aux caractéristiques structurales de la forme susmentionnée du manchon de sertissage. De plus, l'invention permet d'assembler des câbles fermement. Il est possible d'améliorer la capacité anti-tension après le câble de serrage et de réduire la résistance à l'étanchéité et l'augmentation de température de l'étrier. Par ailleurs, l'invention permet d'augmenter la qualité d'étanchéité du câble et de réduire les risques d'accident causé par une coupure de courant de la ligne électrique. De même, il est possible d'économiser de l'énergie et d'élargir le champ d'application de l'étrier sans qu'il soit nécessaire d'utiliser un grand nombre d'étriers.
