Abstract

L'invention concerne des dispositifs d'extinction d'incendies et peut s'utiliser pour protéger des objets allongés tels que câbles ou goulotte de câblage. Le résultat technique de la solution proposée consiste à pouvoir supprimer efficacement l'incendie d'objets allongés lors de l'apparition de feu sur un segment limité. Ce résultat est réalisé grâce au fait que le dispositif d'extinction d'incendies autonome pour objet allongés est réalisé sur la base d'une corde combustible d'extinction d'incendie recouvert d'une enveloppe ignifuge ou partiellement ignifuge non conductrice et étanche aux gaz, et se distingue en ce que la corde combustible d'extinction d'incendie comporte des pièces insérées non combustibles.
