Abstract: A tensioning device includes a circular spring, and a pulley rotatably connected to the circular spring. The pulley includes a circumferential groove, which has a V-shaped cross-section defined by two lateral converging walls. The pulley also includes a flexible rope having a variable cross section, extending between a first end connected to the pulley and a second end intended to be connected to the cable. The pulley is rotatably movable around an axis, between a first position in which the flexible rope is arranged in the circumferential groove around the axis, and a second position in which the flexible rope is unwound.

Abstract: A clamp for a wire of an overhead line comprising a main body has a groove for hosting the wire, a first and a second tapered region located in respective ends of the groove, and a first and a second spring placed in respective holes on opposite sides of the groove. The first and second springs are located in a central portion of the groove and are arranged for pushing respective wedges into the tapered regions in opposite directions. The wedges are arranged for tightening the wire by blocking between the wire itself and a wall of the respective first and second tapered region.
