Abstract：Because Optical fiber composite overhead ground wire (OPGW) have the function of lightning protection and optical fiber communication, which got extensive application in transmission lines. Adopted directly grounded at every tower and graded insulation is common ground way, which makes the OPGW vulnerable to lightning, even worse, can cause OPGW stocks broken. Based on researched grounding system of Optical Fiber Ground Composite Wire, the paper analyzed the result of the lightning experiment for a variety of OPGW grounding modes, and gave the renovation and improvement Suggestions of grounding system.
