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.

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.

Product Description :
Bitumen is widely used in the construction of asphalt roads and bituminous membrane products. Bitumen is commonly used to build highways, motorways and rail networks. Bitumen has excellent water-proofing properties and is widely used for making roofing products along with a range of other household and industrial applications, from emulsion paints to sound-proofing. Penetration Bitumen and Bitumen Emulsions are used for the construction of railway tracks and by using special types of bitumen such as Polymer Modified Bitumen, the vibration and noise levels are reduced due to a dampening effect. Bitumen has been proven to be effective on both high-speed railway tracks and heavy load railway tracks. Bitumen is also used for surfacing airfield runways and air strips (PMB is preffered due to its fuel resistant properties) and taxi ways. For the Marine construction industry bitumen is used for hydraulic applications such as canal lining, underwater tunnels, river bank protection, dam construction and sea defences. There are also numerous industrial applications like roofing felt material, printing inks, packaging paper, linoleum, electrical cable / Junction box insulation, mastic for roofing of terraces, and duplex paper manufacture.

Hollow Section steel Tube is the general name for the steel pipe other than thecircular steel pipe. Such as square, rectangle, oval,elliptical, cone, trapezoidal, spiral, etc. Different steel pipe can more adapt to the particularity of use conditions, save metal and improve the labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, light textile and boiler manufacturing. The methods of producing different pipes are cold pulling, electric welding, extrusion and hot rolling, etc. Compared with the round tube, the different tubes generally have a larger moment of inertia and cross section modulus, and have a large bending resistance and torsion resistance, which can greatly reduce the structural weight and save steel.
Stainless steel tube is a hollow long strip steel made of stainless-steel material. Because of its excellent corrosion resistance, it is mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transportation pipelines and mechanical structural components. In addition, when the bending and torsion strength are the same, the weight is light, so it is also widely used in manufacturing mechanical parts and engineering structures, but also commonly used in the field of furniture decoration.
Stainless steel pipe is divided into seamless pipe and welding pipe according to the production mode, seamless steel pipe can be divided into hot rolling pipe, cold rolling pipe, cold pulling pipe and extrusion pipe, etc., cold pulling and cold rolling is the secondary processing of steel pipe; welding pipe is divided into straight welding pipe and spiral welding pipe.
Stainless steel pipes can be divided into round tubes and different tubes according to the cross-sectional shape. The form tubes have rectangular tubes, rhomboid tubes, ellipse tubes, hexagonal tubes, octagonal tubes and various cross-sectional asymmetric tubes.
It can be divided into Austenitic Stainless Steel Tube Ferritic Stainless Steel Tube Martensitic Stainless Steel Tube and Duplex Stainless Steel Tube by the type of stainless steel.

Cast Iron and Ductile Iron tube and fittings PL739
Cast Iron and Ductile Iron tube and fittings can be offered by our comapny to meet different engineering needs.
The difference between ductile iron and gray iron
1. Different chemical composition
Nodular cast iron contains nodular graphite, which can improve its toughness and strength, while reducing brittleness. Gray cast iron contains a lot of carbon, so that its hardness and wear resistance is high, but the toughness is poor.
2. Different organizational structures
The structure of nodular cast iron contains nodular and ferrite, and the distribution of nodular is uniform. While the structure of gray cast iron is mainly ferrite and pearlite, and the distribution of pearlite is uneven.
3. Different performance
Ductile iron has high strength and toughness, and has good corrosion resistance. It is uitable for the manufacture of high load and high pressure parts. The hardness and wear resistance of gray cast iron are high. It is suitable for the manufacture of friction and wear parts.
Application field
Cast iron : because of its low strength and good vibration resistance. It is often used in the production of parts under compressive stress, such as box, base, etc.
Ductile iron : because of its high strength and good toughness. It is often used in the manufacture of parts requiring high strength and toughness, such as crankshaft, connecting rod and so on.
