vibration damper

This is a pre twisted wire type seismic hammer designed specifically for overhead conductors, mainly used to prevent the slight wind vibration generated by the conductors under wind excitation. The vibration energy is dissipated through the inertia damping effect of the heavy hammer, protecting the conductors and fittings from fatigue damage. It is a key protective component of high-voltage transmission lines.

Core strengths

Pre twisted wire fixation for more uniform force distribution

The spiral structure of the pre twisted wire can tightly adhere to the surface of the wire, evenly distributing the load of the fixed point over a longer contact section, avoiding stress concentration caused by traditional fixtures, and effectively protecting the wire from damage.

Double damping vibration damping, effective

By utilizing the inertial motion of the heavy hammer and the damping effect of the steel strand, the vibration energy of the wire is doubly absorbed, significantly reducing the vibration amplitude and preventing fatigue breakage of the wire due to repeated bending.

Hot dip galvanized anti-corrosion (based on actual reports), with a relatively long service life

The metal parts are treated with hot-dip galvanizing, and the pre twisted wire is made of aluminum alloy material, which has excellent corrosion resistance. The service life can reach more than 20 years in outdoor humid, salt spray and dust environments.

Easy installation effect

Installation can be completed by manually winding pre twisted wires without the need for complex tools, greatly reducing construction time and lowering the risk of high-altitude operations.
