Abstract

Procédé de protection d'un équipement électrique souterrain contre l'emballement thermique. Il consiste à déposer l'équipement dans une tranchée creusée à cet effet qui est remblayée ensuite avec un matériau constitué de la terre enlevée au moment du creusement de la tranchée dans laquelle sont dispersées des particules absorbantes imprégnées deau d'une matière susceptible d'absorber au moins 10 fois son poids d'eau et qui peuvent être revêtues d'une pellicule imperméable à l'eau. Application à la protection des câbles et transformateurs enterrés.
