ADSS Spiral Vibration Damper ,
Features：
Spiral Vibration Dampers using its anti-vibration part to produce antihunt action to the wind vibration, consuming the vibration energy that produced by the cable running under the action of laminar wind,to prevent the destruction of gold tool and fiber optic cable, which mainly used for ADSS cable.
Parameter Table Sheet：
The cable damper is a type of shock absorber that is extremely helpful for small diameter transmission lines and high frequency fiber optical cables, which can be easily damaged.
Purpose
The spiral vibration damper for ADSS is designed to dissipate vibrational energy so as to protect the ADSS cable instalation and cable fitings.
Cautions：
The table sheet as below to confirm the configuration of spiral vibration damper compared to the span of the transmission line
Spiral Vibration Damper is made of PVC material with high strength and elasticity. It is recommended for vibration insulation of ADSS fiber and OPGW fiber when passing over an iced area. Attached the scheme table which is based on the tensility and span of ADSS.
Features
Effectively reduces levels of Aeolian vibration on cables.
Has a helically formed dampening section sized for interplay of damper and cable, to provide the action/ reaction motion that opposes the natural vibration wave. A smaller gripping section gently grips the cable so that cable and fiber are not damaged or distorted and there is no optical signal loss.
ADSS cables tend to vibrate at higher levels than other cables of comparable size, mainly due to their relatively lighter weight. Also the soft nature of their jackets and internal construction requires special consideration.
Preformed Fittings - Preformed Suspension Set
1. Preformed Conductor Suspension Clamp for ACSR Cable Introduction
The preformed suspension clamp is used to fix the wire on the insulator string of the linear tower or to suspend the lightning protection line on the linear tower. It can replace the ship type suspension clamps such as XGU and XGF which are widely used on the line.
The preformed suspension clamp is made of rubber with a hyperbolic waist drum-shaped damping pad, and the anti-vibration pad is wound with aluminum alloy preformed wire. In addition to the preformed wire, a high-strength aluminum alloy casing is installed, and the casing is externally added. Aluminum alloy U-shaped card.
The preformed suspension clamp uses a hyperbolic waist drum-shaped vibration damping pad to wrap the wire around the suspension, and has the characteristics of large grip force, small electric storm, light weight and small magnetic loss. It is especially suitable for 220KV and above lines, as well as heavy ice areas and large span lines.
