This paper analyzes the influence scope, emergency disposal, fault causes and risk characteristics of Jilin snow disaster, and discusses the means of emergency disposal. The paper summarizes the operation years and icing history of optical cables in Henan Province, excavates the causes of icing. Polywater developed an alternative solution: an environmentally safe, freeze-proof gel that is injected into the conduit to dissolve ice, displace water, and permanently fill the void between cable and duct, thus blocking future water infiltration. The resulting product, IceFreeTM Antifreeze Gel.

However, extreme cold, ice, or snow can. Cold weather can affect fiber optic cables, but they are generally more resilient to temperature extremes compared to other types of cables, such as copper. Here's how cold weather can. The U. cities of Ohio, Chicago and Idaho, Quebec, and Ontario of Canada, Russia, Norway, Yugoslavia, Japan, the United Kingdom, Sweden, Finland, and Iceland suffered power transmission line failures caused by snowing and icing [2, 3, 4, 5, 6, 7, 8, 9, 10].
