、実用面できわめて不十分であった。(Problems to be Solved by the Invention) In the prior art described above, the racking resistance, erosion resistance, ultraviolet resistance, and arc resistance of the obtained insulator are limited due to the characteristics mainly due to the glassy properties that can be applied. Therefore, it was extremely inadequate in practical terms.
これは４００℃以下の比較的低い温度で焼結するガラス
を使用せざるを得ないことに起因する。This is due to the necessity of using glass that is sintered at a relatively low temperature of 400° C. or lower.
そのようなガラスは容易に水に溶ける特性を有するため
である。一方上記特性面を満足するガラスを得ようとで
ると高温度で焼結する必要があり、主体の耐熱性の面で
実際、Ｆ採用できないものであった。This is because such glass has the property of being easily soluble in water. On the other hand, in order to obtain a glass that satisfies the above characteristics, it is necessary to sinter it at a high temperature, and in fact, F cannot be used because of its main heat resistance.
