1, product fescription
In the way of high voltage overhead lines, close to the insulator on both sides of the wires are often a small hammer, the small hammer vibration hammer, is to reduce the wire for wind vibration and shame on. High voltage overhead line pole is higher, large span, when there is wind effect of conductor, vibration will happen. The wire vibration, wire hanging in the most unfavorable working conditions. Due to multiple vibration, wire for periodic bending fatigue damage will happen. When overhead line file from more than 120 meters, commonly used shock hammer shock.
T be directly installed on the opgw cables, installed with helical rods.
*calculate the installation distance, if it is within the helical rods, then installed as usual (installed on helical rods directly). If the installation position of vibration damper is outside of the helical rods, you should install helical rods. The distance between the end of the vibration damper and prot ection rods must be more than 70mm.
*the big damper weigh
t of low frequency is close to pole or tower.
*confirm the quantity per span length according to cable strength, span length and topography.
Spiral Vibration Damper
Spiral vibration dampers are motion-control products designed to eliminate wind vibration that can occur across a cable span. Made of weather and corrosion resistant plastic, these transmission line vibration dampers have large spiral shaped vibration dampening sections that fit the size of the cable. A smaller clamping section gently grips the conductor. Using the recommended number of spiral dampers minimizes bending strain and protects the cable from long-term fatigue caused by breeze vibration.
Features
Covers cable diameters from 9.1 mm to 21.0 mm, making the FL Series suitable for a broad range of OPGW (Optical Ground Wire) and ADSS (All-Dielectric Self-Supporting) cable installations.
Designed to reduce wind-induced vibrations and extend the service life of cables and accessories by minimizing mechanical fatigue.
All models feature a 300 mm grip length, ensuring uniform installation and strong holding force without damaging the cable surface.
Available in two total lengths (1350 mm and 1500 mm), the FL Series offers optimized vibration damping performance based on cable size and installation needs.
Each damper weighs less than 0.6 kg, making it lightweight for tower-top installation while maintaining strong structural integrity.
Made from high-quality aluminum alloy or galvanized steel (specify on your site), ensuring long-term durability in outdoor environments.
Spiral Vibration Damper
Spiral Vibration Damper reduces Vibration (the high frequency, low amplitude vibration caused by horizontal wind passing across the line. It is designed to be used on OPGW and conductors with an outside diameter less than 0.75".

Explanatory notes. (1) When the cable diameter is 0.461" and below, a maximum of three SVDs can be installed in one position.(2) On cables larger than 0.461" diameter, only two SVDs need to be combined in order to obtain the best damping performance.
Spiral vibration dampers, also known as helical vibration dampers, are used in the overhead transmission line industry to reduce the vibrations that occur on the conductor due to wind or other external factors. These dampers are typically made of a spiral-shaped metallic wire, which is wrapped around the conductor at regular intervals along its length.
The application of spiral vibration dampers on transmission lines helps to reduce the amplitude of conductor vibrations, which in turn reduces the stress on the line, and prevents damage and failure of the transmission system. These dampers can be installed on overhead transmission lines for both AC and DC systems.
In addition to reducing conductor vibration, spiral vibration dampers also provide protection against galloping, which is a large-amplitude, low-frequency vibration that can occur when the wind blows across the conductor. This phenomenon can cause significant damage to the transmission line and is a major concern for power companies.

Preformed Cable Fittings
1. Usage and characteristics
Spiral Vibration Damper is made of engineering plastic which is high strength,aging resistance and high elastic;it will not cause any mechanical damage to the optical fiber caber.Spiral Vibration Damper is widely used in ADSS cable installation.Each Spiral Vibration Damper is composed of a short part of grip section and a long vibration attenuation section.the grip section can affective close upon the cable to make sure the spiral vibration damper is firmly fixed on the cable; the vibration attenuation section create damping effect through mutual crash with the cable,to consume the cable vibration energy,so that the Aeolian vibration on the cable can be weaken.

1. Usage and characteristics
4D Vibration damper is composed of two different weight hammers stranded galvanization steel wire with high elasticity and high-intensity, and aluminum alloy clamp.
The 4D series Vibration dampers we provided are Stock-bridge Tuning Fork, with four resonant frequencies, the frequency range is from 3Hz to 150Hz. with wide frequency range, the 4D vibration damper can highly consume vibration energy, and effectively dissipate the energy caused by cable Aeolian vibration, reduce cable vibration horizontal, extend the cable service life.
Vibration Damper can be installed on both OPGW and ADSS cable. Armor rods are needed when it is installed on OPGW and ADSS cable.
Armor rods are also called Vibration damper hyperactive rods. Because of the concentrated stress, vibration damper will cause some damages to the cable. the armor rods provide proper stress distribution on the optical cable and protect the cable.
