METHOD FOR INSTALLING A HIGH OR MEDIUM POWER CABLE IN THE GROUND

摘要

The method includes hollowing out a trench, and removing the material from the trench to a treatment unit, for example a crushing unit, and laying a conduit or assembly of three conduits in the trench, and filling up the trench with the treated material and laying in this installation, a high tension electric cable (2) in this conduit (1), on one part, and on the other part, injecting water under pressure in the installation conduit so as to utilize the water as a carrier fluid for removing heat caused by the friction between the cable and the installation conduit.
