Overview
Description:

In order to prevent bird damage and snow ice from forming insulator flashovers, the first shed is designed to increase the design, which has proved to be very effective in recent years.

However, due to the soft texture of the silicone rubber material, when the snow is thick, the super umbrella is easy to pull down and deform, which weakens its protective effect on the umbrella skirt below and easily causes insulator flashover.

For this reason, Chinet has successfully developed a super umbrella with stiffeners. By setting four ribs radiating from the center to four directions on the umbrella, the strength of the super umbrella is effectively strengthened, which can be applied to the environment with heavy snow.
