The bracket includes two support channel steels. The middle parts of the corresponding sides of the two support channel steels are connected with an intermediate channel steel. The two support channel steels are fixedly connected to the ground through a bottom channel steel. Two expansion bolts are installed on the bottom channel steel. The tops of the two support channel steels are connected with an upper channel steel. The connection between the two support channel steels and the upper channel steel is connected by two bolts. In the utility model, the upper end of the support channel steel is connected with the upper channel steel through bolts, and the bottom channel steel is fixedly connected to the ground through expansion bolts, so that the fixed position of the device is flexible, and it does not affect the position of the cable shaft. The design and construction are relatively simple, the structure is simple, the force is clear and reliable, the fixing angle of the upper channel steel is flexible, and it can be flexibly arranged according to the on-site conditions, which is convenient to use. The length of the support channel steel can be adjusted to meet the requirements of leading up and arranging cables at various heights.

[0004] However, in the actual use process of this structure, it can only perform the limiting operation of the fixed high-voltage cable leading-up bracket.
