Vibration Damper
Introduction of Vibration damper:
Vibration damper is kind of protection fitting for high voltage overhead lines, it protects the condutor which is suspend by the insulator or high voltage insulator string. Vibration damper has three kinds of specification,One is stockbridge vibration damper, another is multifrequency vibration damper, Other is ring damper.
Vibration damper by a certain weight, the size of the hammer, high elasticity, high strength galvanized steel wire and high strength aluminum alloy clamp, etc.Parts. Cover wide frequency range, high power dissipation of energy, can effectively lead breeze vibration of dissipation of energy, reduce the vibration levels of lead, extend long wire life. Can be directly installed on the wire, when installed in the overhead ground wire composite (OPGW) on, the need to install the damper on the special care lines.
stockbridge vibration damper vibration damper for overhead power line
stockbridge vibration damper function:
Vibration damper can generate four resonance frequencies which can cover actual OPGW cable vibration range ;After installing Vibration damper, the vibration amplitude of cable reduce syntony so as to suppress the conductor vibrations and ensure lifespan of cable, with satisfactory in vibration.
Vibration damper structure:
Vibration damper is used to protect OPGW cable directly in wind.Vibration damper cannot be installed to OPGW When the installation place of damper is beyond armour rod pre-formed wire, each set of damper should be equipped with one set of armour.
Customer need choose vibration damper according to cable diameter. For the installed Vibration damper, its head at low frequency should toward tower. According to operation strain of cable, spacing and determine the quantity for each spacing.
