あった。2. Description of the Related Art Conventionally, there has been known a polymer insulator composed of a core member, and a shell formed around a core member and a plurality of caps. Conventionally, the jacket of a polymer insulator is generally formed of silicone rubber. In the case of polymer insulators using a silicone rubber jacket, when rain falls, water drops are formed on the cap and some of them have a water-repellent property that they roll down, and no water film is formed on the surface. The leakage current was at a much smaller level than that of the porcelain insulator of No. 1.

なっていた。However, even with the polymer insulator having the silicone rubber jacket having a certain degree of water repellency as described above, some of the water droplets still remain on the shade and the body of the polymer insulator. If the rainfall continues, the water droplets stay on the polymer insulator cap or trunk for a long time, and as a result, there is a problem that the water repellency is temporarily lost in that portion. When the water repellency is lost in this way, a leakage current starts to flow, and a dried arc or the like is likely to occur, which causes deterioration of the jacket.

生頻度を極端に少なくでき、従来のポリマー碍子と比較
して、高寿命化、コンパクト化を達成することができ
る。As is apparent from the above description, according to the present invention, since the water-repellent layer having the very fine irregularities on the surface is provided on the outer cover, the adhesion of water droplets to the outer cover is achieved. And water repellency can be maintained even during rapid soiling such as long-term rainfall or typhoons. Therefore, the frequency of occurrence of a dry arc can be extremely reduced, and a longer life and a smaller size can be achieved as compared with a conventional polymer insulator.
