A comparative study of wear characteristics between aluminized steel, galvanized steel and Q345 was conducted, using scanning electron microscopy (SEM) and energy dispersive spectrometer. Wear weight loss test demonstrated that weight loss of aluminized steel was significantly lower than that of galvanized steel, and the weight loss increased slowly with the loading force. When the loading force increased...
The Euler buckling load of a column is an important parameter to decide its ultimate axial compressive capacity by the column curves. When the closely star-battened angle column under compressive force is designed as an integrated single column according to the British and Chinese Codes, its Euler buckling load about Y axis is greatly overestimated. To solve this problem, firstly, a basic element...
Based on the experiment method, the mechanical properties, adhesion, corrosion performance, appearance of the hot dip aluminized steel, and the thickness of aluminized layer were analyzed. The study showed that, after the hot dip aluminized process, the corrosion performance was improved, adhesion and appearance can meet the requirements of application in transformer substation. But the mechanical...
Primarily, the composite materials currently used in the pole tower are glass reinforced plastic (GRP) composite materials, which is composed of reinforced fibbers and resin. Main disadvantages of pole towers of existing composite materials: small elasticity modulus of composite materials and relatively great tower body deformation. Based on the theoretical calculation, a pole tower of bamboo joint...

Ice shedding from conductors may easily induce electrical and mechanical accidents, which cause serious threat to the safe operation of transmission lines. In this paper, a three dimensional finite element model of tower-conductor-ground wire-insulator system for a 500 kV transmission line was established in ANSYS, and the dynamic responses of ice shedding under different load cases were analyzed...
Application of weathering and cold-formed steel in transmission lines can reduce steel consumption and environmental pollution. Some advances in studies on the weathering and cold-formed steel in transmission tower are introduced. Firstly, corrosion-resistant tests of weathering steel samples under different simulating technical atmospheres were carried out separately for 240 hours. It shows that...
