The weight of the tower varies substantially with height, duty (straight run or corner, river crossing, etc. The range of reported tower weights is 8,500 to. Transmission tower weight per meter varies dramatically by voltage level: 35kV towers average 100-180 kg/m, 66kV systems run 150-250 kg/m, 110kV towers range 200-450 kg/m, 220kV structures reach 350-600 kg/m, and 500kV ultra-high voltage towers require 500-800 kg/m. This weight increases. With 5G expansion, the weight and number of installations have increased rapidly. Engineers must check the tower load capacity to ensure the structure can safely handle these additions. Structural analysis includes. For a 25m structure, Q355B (equivalent to S355JR or Gr50) is the industry workhorse: minimum yield strength of 355 MPa, excellent ductility and weldability. In extreme low-temperature regions (below -20°C), Q355D or S355J2 provides enhanced Charpy V-notch impact values. The heights of transmission towers typically range from 15 to 55 m (49 to 180 ft), although when longer spans are needed, such. The Eiffel Tower weighs approximately 10,100 tons, yet it was designed to be surprisingly lightweight for its size.
