Examples of further measures against snow accretion on bridges and communication cables

Examples of application to bridges, etc.

As a countermeasure against snow accretion, the following two conditions are essential to cause self-weight falling snow.

1. The inclination of the painting surface is necessary (preferably 50 degrees or more)
   → Snow falling angle in snow falling test
2. Unbalanced structure such as snow cutting board is required
   The diagram below shows the need for both super hydrophobic coating and an unbalanced structure such as a snow cutter.

Examples of snow measures for communication lines

" Super hydrophobic cover" that can reduce snow buildup on communication lines
Snow adheres to communication lines in areas with heavy snowfall, and when the amount of snow increases, problems such as disconnection of communication lines and damage to communication line fasteners can occur. Additionally, it is not easy to prevent snow from accumulating on communication lines, as the lines are thin.
Therefore, we would like to introduce an example of a "Super hydrophobic cover"* that can reduce snow buildup on communication lines.

*The lower part of Super hydrophobic cover for communication lines (made of polypropylene) has a structure that opens into two parts, and a stopper is installed on the left and right sides.

Features of “Super hydrophobic cover for communication lines”

The following two functions reduce the amount of snow accretion.

1. Since almost no snow accumulates on the Super hydrophobic cover for communication lines, there are breaks in snow accumulation.
2. The Super hydrophobic cover for communication lines is affected by the wind, causing it to sway more than it would without the cover.
