しかし、以上示した避雷器内蔵筒形高圧カットアウトに
よれば、避雷器収納部がヒューズ筒収納部と平行に位置
しているため、本体碍子を円筒状にすることができず、
異形とならざるを得ない。However, according to the cylindrical high-voltage cutout with a built-in lightning arrester shown above, since the lightning arrester storage part is located parallel to the fuse tube storage part, the main body insulator cannot be made into a cylindrical shape.
It has to be a strange shape.
そのため、形状が複雑になって経済性の点で好ましくな
く、また、持ちにくさ等から取付作業時の取扱い性が悪
く、更に、輸送上梱包形態が大きくなる恐れがある。Therefore, the shape becomes complicated, which is unfavorable from an economic point of view, and it is difficult to hold, making it difficult to handle during installation work.Furthermore, the packaging may become bulky for transportation.
