Title (EN) MULTI-LAYERED PIPE FOR STRUCTURAL CABLE
(FR) TUYAU MULTICOUCHE POUR CÂBLE STRUCTURAL
Abstract:
(EN) The invention relates to a multi-layered pipe (1) for structural cable, a system and a method thereof, comprising a tubular shaped wall (25), the pipe (1) comprises at least a first layer (10) and a second layer (20), wherein the first layer (10) has a thermal resistance higher than the second layer (20), wherein the pipe (1) further comprises at least one heat-generated heating element (30). The present invention combines a passive and an active ice and snow removal system in order to remove ice and snow accreted on structural cables in a cost- effective and efficient manner while minimal consumption of energy is required.
(FR) L'invention concerne un tuyau multicouche (1) pour un câble structural, un système et un procédé associés, comprenant une paroi de forme tubulaire (25), le tuyau (1) comprenant au moins une première couche (10) et une seconde couche (20), la première couche (10) présentant une résistance thermique supérieure à la seconde couche (20), le tuyau (1) comprenant en outre au moins un élément chauffant généré thermiquement (30). La présente invention combine un système passif et actif de dégivrage et de déneigement afin d'éliminer l'accumulation de glace et de neige sur des câbles structuraux d'une manière rentable et efficace tout en nécessitant une consommation minimale d'énergie.
