Icing of wires is a product of rain, fog, and freezing rain, and is a common\nmeteorological disaster in winter in Guizhou Province of China. It is extremely\nharmful to facilities such as power transmission and communication\nlines, and has caused huge economic loss up to 48.9566 billion dollars a year.\nBased on the meteorological records of Guizhou from 1967, we analyze the\nmeteorological characteristics during the icing of wires, and obtain the temperature,\nwind speed and direction conditions of the ice accident. The icing of\nwires is carried out by supercooling raindrops, freezing of the clouds, freezing\nand spreading on the wires. Different types of supercooled raindrops and\ncloud freezing and freezing processes will form different types of ice accretion;\nwind direction and wind speed will affect the growth of ice accretion by\nchanging the speed of sub-cooling raindrops and cloud falling. The weight of\nrain-type ice accretion is between 24 and 152 g, and the weight of smog-type\nice is between 40 - 76 g. The average ice density of these two places can be\ncalculated to be 0.2 - 0.5 g/cm3. The longer the icing of wires, the higher the\nice disaster rate.
