Linear rod insulator shielding cover

The invention discloses a linear rod insulator shielding cover which comprises a first shielding cover and a second shielding cover which are arranged up and down, one side of the first shielding cover is rotatably connected with one side of the second shielding cover, and the first shielding cover is of an inner and outer double-layer structure and is buckled with a stepped structure at the top of the second shielding cover in a matched mode. The first shielding cover and the second shielding cover are buckled to form a first containing cavity, a second containing cavity and a third containing cavity, the first containing cavity and the third containing cavity are located on the two sides of the second containing cavity respectively, and the second containing cavity contains a linear rodinsulator porcelain bottle. By means of the structural design, one-time in-place operation can be achieved, electric breakdown is effectively shielded, safety is improved, and meanwhile the overall efficiency of operation is
