Zusammenfassung:PROBLEM TO BE SOLVED: To provide an insulator for high-voltage power distribution which can prevent tracking and insulation breakdown by making a dark current smaller and does not cause ground fault/short circuit even when snow containing a salt content covers an entirety or intrudes into the inside of the insulator body.SOLUTION: An insulator for high-voltage power distribution includes a metal shaft 2 that is cemented to a center of a ceramic insulator body 1, in which a water-repellent silicone resin film 10 covers all from a ceramic insulator body 1 to a cementing part 3, and is formed continuously to a surface of the metal shaft 2. As the high-voltage power distribution insulator, a high-voltage pin insulator and a high-voltage vibration resistant insulator can be exemplified.SELECTED DRAWING: Figure 1 【課題】漏れ電流を小さくしてトラッキングや絶縁破壊を防止することができ、塩分を含む雪ががいし全体を覆ったり、がいし本体の内部に入った場合にも地絡・短絡事故に至ることがない高圧配電用がいしを提供する。【解決手段】磁器製のがいし本体1の中央に金属軸2がセメンチングされた高圧配電用がいしであって、撥水性のシリコーン樹脂皮膜10が磁器製のガイシ本体1から始まり、セメンチング部3のすべてを覆い、金属軸2の表面まで連続して形成されている。高圧配電用がいしとしては、高圧ピンがいし、高圧耐張がいしを例示することができる。【選択図】図1
