DEVICE LIMITING DANCING OF WIRES, GROUND WIRES OF OVERHEAD TRANSMISSION LINES AND FIBRE OPTIC CABLES OF OVERHEAD LINES, AND PASSAGE EQUIPPED WITH SUCH DEVICES (VERSIONS) Russian patent published in 2015 - IPC H02G7/14 

FIELD: electricity.

SUBSTANCE: device consists of torsion limiter installed eccentrically in regards to a wire and torsional vibrations exciter installed at the wire through a spiral protector so that its centre of mass is placed sideways from the wire longitudinal axis and located in horizontal plane. The torsion limiter is made as a closed body with guides and springs installed in it with rigidity of C=c₁, c₂, …, c_n and loads with mass of M=m₁+m₂…+m_n and shaped openings, at that the body is filled with gas or antifreeze. The torsional vibrations exciter is made as per the similar design; the exciter is placed at the distance of 1.5-5.0 m from the torsion limiter.

EFFECT: intensive torsional vibrations of a wire, ground wire or cable with torsion limiters and torsional vibrations exciters installed at them are active dampers promoting intensive aerodynamic damping of their vibrations at dancing.
