文摘The icing disaster data and field investigation data of conductor icing were analyzed,the results indicated that conductor icing is mostly mixed freezing of glaze and rime in Guangxi,it becomes more severe with the higher of latitude and the increasing of altitude;the thickness of windward side is larger than leeward side in the same elevation.The closer to reservoir and rivers,the more serious the icing degree is.When cold wave broke,southwest warm-moist airflow was transported like an endless stream to the upper air of South China and surface stationary front sustained in South China coast.The main reasons of coming into being conductor icing were a stable strong frontal zone sustained in the upper air in Guangxi and there was strong inversion layer in the middle and lower troposphere,at that time,it was easy to generate conductor icing.The terrain generated an important effect on conductor icing.
