Insulator for salt and dust density component sampling of power transmission line

A vertical connecting piece a fixedly penetrates through one end of a fixing plate, a connecting plate is arranged at the other end of the fixing plate, a transverse connecting piece b fixedly penetrates through the connecting plate, the connecting piece a and the connecting piece b are the same in structure, and square holes are formed in the centers of the connecting piece a and the connecting piece b in the length direction of the connecting piece a and the connecting piece b. The upper end and the lower end of the outer surface are provided with connecting screw holes, connecting screws are arranged in the connecting screw holes, the vertical insulator is located above the connecting piece a, the transverse insulator is located at the side end of the connecting piece b, and the two ends of the vertical insulator and the two ends of the transverse insulator are fixedly connected with square blocks matched with the square hole structures. Through holes are formed in the upper end and the lower end of the ou
