Cable support used in electric power engineering

The utility model discloses a cable support used in electric power engineering, which comprises a cable support main body, two sides of the bottom end of the cable support main body are fixedly connected with bases, two sides of the cable support main body are provided with notches, and the notches of the cable support main body are transversely provided with adjusting frames in a penetrating manner. The top end and the bottom end of the adjusting frame are fixedly connected with side supports, and one side of each side support is fixedly connected with a sliding block. According to the cable support used for the electric power engineering, the support is limited and fixed by arranging the sliding rails, the side supports, the adjusting frames, the sliding blocks, the fastening bolts, the positioning grooves and the positioning rotary knobs, it is ensured that a cable cannot fall off during supporting, meanwhile, the application range of cable fixing is expanded, and the problem that the height of a fixing st
