Corona Coil

The ADSS-CORONA Coil is installed over the ends of the Structural Reinforcing Rods of FIBERLIGN Dielectric Dead-ends or Dielectric Suspensions. The gripping section securesMthe unit to the Structural Reinforcing Rods and the coil section encircles the metallic rod ends, providing electrical shielding.Proper installation and positioning over the ends of the Structural Reinforcing Rods is crucial to the performance of the ADSS-CORONA Coil.

Product Introduction

Corona Coil

9(1)_01



Fiber optic technology has revolutionized the way we transfer and process data, and has become an essential component of modern communication systems. To ensure the smooth operation of these systems, it is essential to maintain the integrity of the optical signal. However, one of the challenges that can arise is the presence of corona effects or high-voltage discharge in the fiber optic cable.


To overcome this issue, the installation of corona rings is a technique widely used in the fiber optic industry. A corona ring is a series of conductive devices that encircle the cable at regular intervals to prevent the buildup of static electricity. It is commonly used in overhead power transmission systems, and its application in fiber optics is a concept that has been adopted in recent times.


The primary purpose of corona rings in fiber optics is to prevent corona discharge from the power lines attached to the cables. This discharge can interfere with the optical signal, leading to degradation and even complete signal loss. Corona rings ensure that the voltage present on the cable is below a certain threshold level, minimizing the chances of signal distortions. They are installed at regular intervals, usually 500 feet apart, along the length of the cable.


Corona rings come in various forms, shapes, and sizes, catering to a range of different cable diameters. They can be modified to fit various cable configurations and attached using clamps or cable ties.


The benefits of installing corona rings on fiber optic cables are numerous. Firstly, they provide increased efficiency and reliability. By preventing the buildup of static electricity and high-voltage discharge, corona rings ensure that the signal is transmitted effectively and without degradation. This, in turn, translates into a more reliable and efficient communication system.


Secondly, they provide cost savings. Any signal distortion can lead to lost productivity, unproductive downtime, and potential revenue loss. Corona rings can help prevent these unwanted costs by ensuring the transmission of clean, undistorted signals, leading to fewer maintenance-related expenses and an increase in the lifespan of the cable.


Finally, corona rings can also add an extra layer of safety for users. By reducing the amount of static electricity present on the cable, they minimize the risk of electric shock, ensuring a safer working environment for workers.
