Package structure and packaging method of post insulators

Номер: CN102689745A
Автор: Ma Yongxu, Wang Zhanjie, Sun Yuzhou, Hu Yantao
Принадлежит:

The present invention discloses a package structure and a packaging method of post insulators, wherein the package structure of the post insulators comprises insulators which are vertically disposed in parallel and have upper and lower flanges; top connecting pieces fixedly connecting together the upper flanges of the insulators are disposed above the insulators; bottom connecting pieces supporting the insulators and fixedly connecting together the lower flanges of the insulators are disposed below the insulators; and peripheries of the insulators are provided with wrappages for protecting the peripheries of the insulators. In the package structure and the packaging method of the post insulators, the top connecting pieces and the bottom connecting pieces are adopted to connect the vertically disposed insulators, satisfying intensity requirements during processes such as loading and unloading as well as transport of the post insulators; wrappages are adopted to wrap the peripheries of the ...
