Insulators To Prevent Ice And Snow Natural Disasters In Winter

"According to the national statistics on ice coverage, although the temperature in the north is low, heavy ice coverage is less common due to the dry climate.

Even if it occurs occasionally, it does not pose a big threat to the power transmission line composite suspension insulator because the amount of ice coverage is small. In winter, the high-altitude areas south of the Yangtze River with high-altitude southwesterly warm and humid air currents are more seriously affected by ice coverage disasters."

Did you see it clearly? "According to the national statistics on ice coverage", "in winter", "the high-altitude areas south of the Yangtze River are more seriously affected by ice coverage disasters" - it can be seen that the icing of transmission lines in winter is not a "feature" of the north, but a "chronic disease" of the south; it did not start today, but has existed for a long time, and has long been recognized, counted, and studied.
