OPGW Cable Spiral Stockbridge Vibration Dampers


The vibration damper in transmission line is mainly used to reduce the vibration caused by wind. High-voltage overhead lines have higher pole position and larger spacing,when the wires are subjected to winds, When the wire of transmission line will vibrate.When the wire vibrate, the working conditions are very unfavorable in the position where the wire hung. Due to vibrations,The fatigue damage of the wire will happen caused by periodic bending.When the spacing of overhead line is greater than 120 meters, the general use of vibration dampers.


Line fittings are metal parts used to connect transmission line towers, conductors, lightning wires and insulators, or protect conductors, lightning wires, insulators and so on. They are usually made of cast steel and malleable iron. The line fitting shall be of sufficient mechanical strength and shall have good electrical properties for the fittings that connect the conductor. According to its performance and use, can be broadly divided into: Suspension Clamp, Strain Clamp, Link Fitting, Splicing Fitting, Protective Fitting,Guy Wire  Fitting.
