VIBRATION DAMPER


Vibration dampers

Dampers are installed on the wires and cables of power lines to prevent them from damaging the fatigue stresses caused by vibration.

For installation on overhead wires are used vibration dampers such as hepatitis GV, GVN or GPG. To install on wires big transitions - such as dampers GPG with a "blind" attachment or vibration dampers such as GPS reset.

Vibration dampers are equipped with all types of dies with lower magnetic losses. Place of installation of vibration dampers, their brand and number are determined by the "Guidelines for the Protection of the type of vibration ..." developed VNIIE.


 Vibration dampers type GV

 


   

Vibration with a blind attachment to the cable (ground wire) is for vibration damping of non-metallic optical cables and cables embedded in the ground wire of overhead power lines big hits.
Dampers meet the requirements of GOST 13276.
