发明名称 Mechanical tension-limiting device for protecting cables and pylons from mechanical overloads
摘要 The device comprises at least one drum 21 arranged transversely with respect to the direction of the forces exerted on the support by the cable 1 to be supported and mounted so as to be able to rotate freely with respect to two linkage rods 31, 32 both connected to one of the elements constituted by the cable 1 to be anchored and the support 4, and a deformable element 10 comprising at least one turn 13 wound around the drum 21 and a first end 11 terminated in the form of a connecting ring 12 so as to allow the connection to another of the elements constituted by the said cable 1 to be anchored and the said support 4. The deformable element 10 is suitable for being deformed plastically beyond a predetermined elastic limit and has a coefficient of elongation at break greater than approximately 20%. Application especially to conductors and supports of overhead power lines. <IMAGE>
