Application and development of high strength aluminum alloy structure in power transmission and transformation engineering

High strength aluminum structures are widely used in foreign electric transmission towers and substations. However, domestically they are mainly used in long-span roof structures and footbridges of small live loads. Hence, the application of aluminum structures in domestic transmission towers and substations requires further development. High-strength aluminum material features light weight, high strength, good corrosion resistance and high recycling value. It is also a simple process in terms of manufacturing and construction. This paper conducts a survey of some typical engineering projects and studies the advantages of applying the aluminium structures in these projects with consideration of the physical and mechanical properties of the aluminium alloy. Base on the results, some suggestions are made for the further investigation and application of aluminum structures in the electric transmission towers and substations.
