る仕切板を備えたことを特徴とする防雪形ブッシング。It has a coil spring for the center clamp method that fixes the upper insulator tube, lower insulator tube, and main flange through the center conductor, and an expansion chamber containing inert gas to suppress abnormal pressure caused by expansion and contraction of insulating oil and insulating oil. In the bushing, a cone-shaped or pyramid-shaped snow cover that communicates with the expansion chamber and forms a sealed container with the expansion chamber is installed on the expansion chamber, and a partition plate that serves as a head cover is installed within the snow cover. A snow-proof bushing characterized by the following.
