How can snow collect on thinner power lines and damage them?

Arab weather - Ice crystals gather to form snowflakes that fall quietly on the ground, covering everything on them. In certain circumstances, these snows can damage trees and power lines suspended between columns, which leads to a major power outage in homes, so how can some beads Will the accumulated snow cause all this damage?!

 

Power lines running in the air between poles can be damaged in three ways:

  • Ice weight.
  • Tree branches break and fall on power lines.
  • Wind that causes the lines to sway.

 

Snow falls and some of it sticks to power lines and tree branches, but the greatest damage does not occur from the accumulation of this snow, but rather from what is called freezing rain, which occurs when there is a warm layer on top, when rain falls through a warm layer in the atmosphere and melts, then it falls on A surface on which snow has accumulated so that the temperature of this surface is below freezing, freezing on top of it and forming a heavy layer of ice that damages trees, causes power lines to fall and eventually break.

 

A small amount of ice adds a lot of weight to power lines, and tree branches that bend or break on power lines can compound the effect of the ice, making the wires more likely to fall.

 

Strong winds can also exacerbate the effect of ice on power lines. When wind speeds reach 20-25 miles per hour, power lines begin to sway, this movement causes electrical wires to break or touch each other, and eventually leads to power outages. .
