Antivibration power fitting
1.Preformed armour rod:
In order to achieve the purpose of anti-vibration,choose the wire with strong corrosion property is selected, which is preformed into spiral shape, and tightly wound in the outer layer of the wire to improve the rigidity of the wire.
2.vibration damper
The right chosen vibration damper can reduce more than 90% vibration force of overhead wires generally.Therefore,the following should be considered when choose vibration damper:
(1)wind speed,wind energy,temperature and landscape;
(2)Self-damping property of wire;
(3)relationship between vibration level and strain;
(4)balance of power.
