Spiral Vibration Damper Enhancing ADSS Cable Performance_NEWS

Abstract

The Spiral Vibration Damper for ADSS Cable is an essential component in the field of optical fiber communication. It plays a crucial role in reducing the vibration and wind-induced aeolian vibration of ADSS (All-Dielectric Self-Supporting) cables, ensuring their stability and reliability. This article aims to provide a detailed explanation of the Spiral Vibration Damper for ADSS Cable from four aspects: its function, structure, installation process, and benefits.

1. Function

The primary function of the Spiral Vibration Damper is to dampen vibrations that occur on ADSS cables due to various factors such as wind or external forces. These vibrations can lead to excessive stress on the cable, potentially causing damage or even failure. The damper absorbs these vibrations by converting them into heat energy through frictional resistance.

In addition to damping vibrations, this device also reduces wind-induced aeolian vibration. Aeolian vibration refers to the oscillation caused by airflow passing over a cable's surface at certain speeds or under specific conditions. The spiral design disrupts smooth airflow around the cable, minimizing aerodynamic effects and reducing potential damage caused by aeolian vibration.

Overall, the Spiral Vibration Damper enhances cable stability and longevity by mitigating both random vibrations and those induced by environmental factors.

2. Structure

The damper consists of several key components that work together harmoniously:

Spiral Body: This is where most of the damping action occurs. It is typically made from high-quality aluminum alloy with excellent corrosion resistance properties. Damping Material: Located inside each spiral groove are specially designed rubber inserts that provide optimal frictional resistance against vibrational forces. Holding Clamp: Used for securely fastening multiple spirals onto an ADSS cable without causing any damage or strain on its outer sheath.

Installation Process

The installation process involves several steps:

Cable Preparation:

Prior to installing dampers, it is crucial to ensure proper cleaning and preparation of the ADSS cable's surface where they will be attached.
