The paper analyzes hazard on overhead ground wire icing of transmission line. In order to melt ice on overhead grounding wire, the paper puts forward the necessity of overhead ground wire ice melting char-acteristics. By use of walk-in temperature and humidity chamber, temperature tester and large current gener-ator and other equipment, ground wire icing under different environmental conditions is simulated in laborato-ry and ice melting tests are conducted with different current values;rules of ice melting under different icing thickness and current values are summarized, and calculation correctness of ice melting current theory; be-sides, communication function before and after ice melting of OPGW is tested, from which a conclusion is drawn that the communication function can not be influenced by ice melting current.
