| Abstract: | Sampling and checking is conducted on some composite insulators to research their aging degree in Guangzhou network.47 composite insulators in 5 power lines have experienced visual inspection,hydrophobi-city test,power frequency voltage withstanding test in dry status,steep wave experiments and power frequency voltage withstanding test after boiling,withstanding test with 50% rate mechanical load,sealing test and mechanical failure test etc.The test results show that the aging problem of composite insulators needs concern from operation division. |
