Study on OPGW Cable Grounding Technology in Power System

Abstract

In electric power communication, OPGW cable plays an important role. In recent years, the natural arch secondary power station to reduce the OPGW stops communication optical cable frequent lightning strike or grid CLP Pressure discharge gap, led to the suspension of OPGW cable wire broken stocks fiber core fault, transmission of power communication business caused great threat. How to improve the lightning protection level of OPGW cable, let OPGW cable for electric power communication services safely and reliably, it is a problem worth our study. This article from the mechanism of OPGW cable damage caused by lightning, and analyzes the OPGW cable broken stocks of the original, and expounds the OPGW cable lightning protection level of improvement measures, further put forward through good grounding method effective measures to improve the level of OPGW cable lightning protection.
