A Programme to Solution the Problem of OPGW Substation Structure Grounding

Abstract

OPGW with functions of lighting proof and communication is widely used in the construction of power network. For optical fiber composite overhead ground wire (OPGW), it is required to achieve the separation of wire and signal after the introduction of the substation structure[1]; at the same time, the grounding for lightning proof is also required because of the frequent occurrence of the burnout of the optical cable and short circuit due to the electric discharge and lighting as a result of the problems in the grounding device or construction. This paper analysis some common advantages and disadvantages of OPGW structure grounding methods. In combination with the practical conditions of the project, the solution “Enhanced the grounding method” is brought up and solve the practical problem.
