Examples of further measures against snow accretion on bridges and communication cables
Examples of applications to bridges, etc.
To prevent snow accumulation and allow snow to fall off due to its own weight, the following two conditions are essential:
- The inclination of the painting surface is necessary (preferably 50 degrees or more)
→ Snow falling angle in snow falling test - Unbalanced structures such as snow-cutting plates are required.
The diagram below illustrates that both super hydrophobic coating and unbalanced structures such as snow-cutting plates are necessary.

Super hydrophobic cover that can reduce snow accumulation on communication lines
In snowy regions, snow can accumulate on communication lines, and if the amount of snow buildup increases, it can lead to problems such as the lines breaking or the fasteners on the lines becoming damaged. Furthermore, preventing snow accumulation on communication lines is not easy due to their thinness.
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 the "Super hydrophobic Cover for Communication Cables"
The following two functions reduce the amount of snow accretion.
- Since almost no snow accumulates on the Super hydrophobic cover for communication lines, there are breaks in snow accumulation.
- The Super hydrophobic cover for communication lines is affected by the wind, causing it to sway more than it would without the cover.
