The utility model discloses a FTU control box support. The utility model discloses a frame is fixed with the mount, on the fixed externally wire pole of mount for the FTU control box without the direct mount on the wire pole, guaranteed the FTU control box and can fix on the wire pole by stable quilt. The structure of mount sets up to make wins semi -ring and second semi -ring after the combination, and connection area between the two is big, has guaranteed whole support and has fixed the fastness and the security of the FTU control box on the support. Reinforcement panel's mount overall structure's stability has obtained further promotion, the setting of bearing bar, the holistic stability of frame has been increased, reduce the deformation ratio of frame as far as, bearing bar and mount all are equipped with two and position between them corresponding setting each other, make the overall stability of support obtain the guarantee, be difficult for taking place great deformation after installing the FTU control box, even difficult the emergence is deformed or is become flexible under the condition of bad weathers such as blowing hard, lead to the occurence of failure.
