The invention concerns a method for setting medium or high power electric cables (2) in the ground, which consists in digging a trench (14), evacuating the materials derived from the trench (14) towards a treatment device, for example by crushing, depositing at least a duct or an assembly of three installation ducts in the trench (14), backfilling the trench (14) with the treated materials and setting in said installation duct (1), at least a medium or high power electric cable (2) by pushing it while injecting water (6a) under pressure into the installation duct (1) so as to use the water (6a) as carrier and discharge fluid for the heat energy resulting from friction between the cable (2) and the installation duct (1).

La présente invention concerne un procédé pour disposer des câbles électriques (2) de moyenne et forte puissance dans le sol, consistant ô creuser une tranchée (14), ô évacuer les matériaux issus de la tranchée (14)vers un dispositif de traitement, par exemple par concassage, ô déposer au moins un conduit ou un assemblage de trois conduits d'installation dans la tranchée (14), ô remblayer la tranchée (14) avec les matériaux traités et ô installer dans ledit conduit d'installation (1), au moins un câble électrique (2) de moyenne ou forte puissance d'une part en le poussant, et d'autre part, en injectant de l'eau (6a) sous pression dans le conduit d'installation (1) de manière ô utiliser l'eau (6a) comme fluide de portage et d'évacuation de l'énergie thermique résultant des frottement entre le câble (2) et le conduit d'installation (1).
