揮できないためである。The particle diameter of the high dielectric substance is not particularly limited, but the average particle diameter is preferably 0.1 to 50 μm, and more preferably 0.1 to 5 μm. The reason is that if the average particle size of the high dielectric constant substance is less than 0.1 μm, the surface area becomes too large and water is easily absorbed, and if the average particle diameter exceeds 50 μm, the mixing property with the insulating polymer material is poor, and the This is because mechanical strength cannot be exhibited. The amount of the high dielectric substance is not particularly limited, but is preferably 1 to 100 parts by weight, more preferably 10 to 30 parts by weight, per 100 parts by weight of the polymer of the insulating polymer material. The reason is that if the compounding amount is less than 1 part by weight, the dielectric constant of the applied portion does not become large, there is no effect of suppressing discharge,
If the amount exceeds the weight part, the mechanical strength required for the jacket material cannot be exhibited.

When the jacket 5 is made of silicone rubber, its composition is such that silica fine powder 1 to 5 is added to 100 parts by weight of silicone polymer.
It is preferable to use a rubber in which the high dielectric substance is mixed with a rubber containing 0 parts by weight and 0 to 300 parts by weight of aluminum hydroxide powder.

Examples of the present invention in which a high dielectric substance having a type, a blending amount, and an average particle diameter shown in Table 2 below and a high dielectric substance was contained in an application site shown in Table 2 below were used. Composite insulators of Comparative Examples 1 to 9 and Comparative Examples 1 to 3 were prepared. Here, only the power-applied side of the application site means up to the middle trunk of the first and second shades from below, as shown in FIG. 1B. For each prepared composite insulator, tracking resistance, maximum electric field, and corona generation voltage were determined. The tracking resistance was determined according to the tracking resistance test of Method 1 of IEC60587 standard. The maximum electric field was 10 in Comparative Example 1.
The ratio when it was set to 0 was determined by computer simulation based on the dielectric constant and compounding amount of each substance. Where 10
0% is about 300 V / mm. The corona generation voltage was applied to the composite insulator by changing the applied voltage to obtain a voltage at which corona was generated. The results are shown in Table 2 below.

ことができる。As is apparent from the above description, according to the present invention, all or a part of the jacket made of an insulating polymer material such as silicone rubber is preferably of a predetermined particle size and a predetermined amount. Since the dielectric material is contained, the whole or part of the outer cover of the composite insulator can be made to be resistant to an electric field. As a result, the applied electric field can be relaxed to suppress corona discharge, and a longer life can be achieved. In addition, since the whole or a part of the outer cover can be configured to be resistant to an electric field, its body diameter and overall length can be reduced, and the shape of the composite insulator can be made more compact.
