| Abstract: | Since its commission on May 16 of 1998, the 500 kV Tianping 5405 line has repeatedly suffered fracture accidents of its optical fiber composite overhead ground wire (OPGW), which poses a great thread to the safe operation of East China Power Grid. Through field investigation, operation statistics, metallic microanalysis of the fractured OPGW sample, as well as tests of lightning and short-circuit current, the main causes of OPGW fracture accidents suffered by the Tianping 5405 line was found out, and the relationship between the OPGW material, structure, and the wire fracture are analyzed. |
