Product Description
Description:

The spiral vibration isolator is mounted on a small diameter wire or ground wire to reduce the wire or ground breeze vibration.

The spiral vibration damper consists of a relatively short grip section and a relatively long damper section. The gripping section can effectively hold the cable, and the spiral anti-vibrator is firmly fixed on the cable; the anti-vibration section beeps and the thread-by-wire collision, and the breeze vibration on the body line is strong. The material uses a solid to be hydrogen 7 ene.

4D series sound and anti-vibration damper, with high frequency coverage, 3Hz~150Hz, four anti-vibration frequencies, providing complete frequency protection and perfect characteristic performance

Features:

1. The spiral anti-vibration device has good anti-vibration effect for suppressing high-frequency breeze vibration of the wire.

2. The 4D series anti-vibration damper provided by chinet Company is designed by Stoke Bridge sound and multi-resonance sound damping device, which is mainly used to weaken and disperse the lightning energy generated by the breeze vibration to the cable.

3. Easy to install: no need for any special tools, free and easy to install on-site, one person can complete.

Notes:

1. The grip part of the spiral vibration isolator should be installed at a distance (30cm) from the guard line or other fittings.

2. The anti-vibration device can be reused in the case of good appearance.

3. Anti-vibration damper installation damper head orientation: the damper head toward the iron tower.

Consider two factors when selecting the model. One is the damper head and the other is the diameter of the installation wire.

Considering the main technical parameters of the guide/ground line, such as tension, wind speed, topography and other factors, determine the anti-vibration damper.
