The embodiment of the utility model discloses an ultra-high voltage tension tower conducting wire hanging point system comprising a crossarm principal material, an angle iron and a connection plate, wherein, the crossarm principal material is arranged on one side of the connection plate, the angle iron is arranged on the other side of the connection plate, the angle iron is provided with a short angle iron and a first hanging wire steel plate provided with a first hanging wire hole, the short angle iron is provided with a second hanging wire steel plate with a second hanging wire hole, the first and the second hanging wire holes are positioned on the same horizontal line, and a hanging point hardware fitting is arranged between the first and the second hanging wire holes. With the hanging wire steel plates welded together, the utility model is flexible on the choice of the length of the steel plates, so that the hanging holes of a plurality of hanging wire steel plates can be positioned on the same horizontal line, thereby preventing the head of the hanging wire iron from severe bending. Moreover, the hanging point system is not connected with other iron tower rod pieces except being directly connected with the crossarm principal material, thereby solving the problem that the need to disassemble other connection horizontal materials in the disassembly of the hanging wire angle iron makes repair more arduous.
