PROCESS AND TOOL FOR PLACING ON THE SOIL AN OVERHEAD ELECTRICAL LINE WIRE-SPACER, AND SPACER THEREFOR

摘要

The spacer (4) comprises an elongate body (8) terminated by two heads (9a, 9b) having grooves (13a, 13b, 13c) for the electrical conductors. These grooves may be closed by retention components (18a, 18b) which can slide with a significant friction inside openings (14). The tool (6) comprises dish-shaped elements (42a, 42b) for positioning the heads (9a, 9b), a component (44) for locking the spacer (4) onto the dish-shaped elements (42a, 42b), levers (53a, 53b) detachably coupled to the retention components (18a, 18b) and to traction cables (57) running alongside a pole (7) in order to enable the retention components to be actuated from the base of the pole, and a ratchet (48) controlled by a cable (52) in order to enable the locking component (44) to be returned by its spring (47) when, after placing the spacer onto the conductors, it is required to separate the tool from the spacer. At one of its ends, the spacer comprises a groove (13b) to be used when the electrical conductors have a tendency to move apart and a groove (13c) when the opposite is the case. Use for easy and safe placing from the ground.
