Preferably, a plurality of pairs of bottom supporting tables 5, two side supporting tables 6 and three uniform pressing tables 7 which are uniformly spaced are arranged in the box body 1 and the box cover 2, so that a plurality of serially connected disc-shaped suspension insulators 9 can be clamped simultaneously, the stability of the insulators in the process of carrying can be ensured, and the carrying efficiency is high.

Preferably, the bottom supporting platform 5, the two side supporting platforms 6 and the three uniform pressing platforms 7 are made of hard plastic, and the total material is light in weight and good in hardness. The outer surface material of the box body needs to be wear-resistant and corrosion-resistant, and the inner material of the box body needs to be made of rubber materials, so that the box body is prevented from being hard to touch the insulator.

Preferably, the groove surface of the clamping groove 8 is provided with a sponge layer, so that the effect of buffering and protecting the insulator can be further achieved.

Preferably, the bottom support platform 5, the two side support platforms 6 and the three uniform pressing platforms 7 are detachably connected to the box body 1 and the box cover 2, the majority of insulators used in a 110kV line at present have two types of insulators with electrical breakdown loads of 70kN and 100 kN, the heights of the two types of insulators are 146-160 mm, and the diameters (outer diameters) of the insulators are 255-280 mm. If 4 pieces are strung according to a group (called a No. 4 box for short), the length of the inner size of the No. 4 box is 4 multiplied by 146 mm-4 multiplied by 160mm, and the width and height of the inner size of the No. 4 box are 255-280 mm of the outer diameter of the insulator; the external dimension (length × width × height = L × M × N) of the insulator protection box is obtained by adding the design and manufacturing thickness of the used material to the internal dimension of the insulator protection box, and the overall external dimension of the insulator protection box can be calculated in consideration of the variable ranges of the dimensions of the insulators of two different electromechanical damage load types and the appropriate movement margin. Through detachable construction, can change inside insulator strong point structure to adapt to the insulator of equidimension not and use, box reuse reduces haulage equipment cost.

In addition, the protective case has other useful aspects.

1. In the process of carrying the previous maintenance materials, a special basket carrier is needed to be found to carry the insulator to ascend to the top and reach the position of a tower to be maintained, after the insulator protection box is used, a single person or double persons can hold the protection box by hands and arrange a handle buckle or a handle buckle outside, a human body (or shoulders) contacts with a semicircular cambered surface of an upper cover to carry the insulator, and a bottom box (the appearance is rectangular) is placed in contact with the ground when in midway rest, so that the insulator protection box can be prevented from rolling and overturning anywhere on an uneven mountain land;

2. when the salt density and the ash density of the insulator are measured, the insulator picked on site is packaged by a plastic bag and then is placed into an insulator protection box, so that the falling off of ash attached to the surface of the insulator due to shaking is prevented, and the accuracy and the authenticity of a measured value are guaranteed.

Generally, the number of single insulator strings of a 35kV power transmission line is 3, 4 or 5, the number of single insulator strings of a 110kV power transmission line is 7, 8 or 9, and insulator protection boxes with proper models are selected to be transported according to the number of the repaired and replaced insulators. When 3 or 4 insulators are replaced, a No. 4 box is used for carrying; when the number of the insulators is changed into 5, 7 or 8, the insulators are carried by using two No. 4 boxes; when 9 insulators are replaced, three No. 4 boxes are used for carrying.

After the boxing is finished, the upper cover is covered, and the lock catch is locked.
