FIELD: securing multi-wire conductors of aerial power lines suspended from cross-members of power line towers forming spans. SUBSTANCE: at least one multi-wire conductor runs rectilinearly; it is secured by means of bracing strut articulated to corner points of equilateral triangular frame, with top of clamp directed downward. Triangular frame is connected with insulator by means of holding bracing strut articulated to lower corner point. Holding bracing strut is connected with upper corner points of triangular frame by means of vibration damper. EFFECT: enhanced reliability. 6 cl, 4 dwg
