Galvanized power transmission steel pipe tower: The main components are made of steel pipes, while other components are composed of lattice type towers made of steel pipes or profiles. It is a supporting structure for overhead transmission lines to support conductors and lightning conductors. Ensure that the wire meets the distance requirements for the ground and ground objects, and can withstand the load and external load of the wire, lightning wire, and itself.

Main Features:The galvanized power transmission steel pipe tower structure has relative technical and economic advantages, and is suitable for application in transmission towers that bear large loads.

(1) Load characteristics

Galvanized power transmission steel pipe tower members have low wind pressure, high cross-sectional bending stiffness, simple structure, and clear force transmission, which can fully utilize the load-bearing performance of materials. On the one hand, it can reduce the weight of the tower and reduce the foundation force; On the other hand, it is beneficial to enhance the ability to resist natural disasters under extreme conditions. Under the condition of meeting the requirements for strength and stability calculation, using steel pipe towers with relatively small wind pressure shape coefficients can significantly reduce the wind load on the tower body.

(2) Cross-sectional characteristics

The section center of the steel pipe component is symmetrical, and the section characteristics are isotropic; The material is evenly distributed around the perimeter, and the cross-sectional bending stiffness is high. For the tension rod components of transmission towers, when the cross-sectional area of the steel pipe and angle steel is equivalent, the steel pipe tower members do not show their advantages. For the bending and compression components of transmission towers, using steel pipes with smaller cross-sectional areas and larger turning radii can fully balance the mechanical properties of the materials, meet the structural stiffness and stability requirements. Especially for large load iron towers with larger geometric dimensions and longer members, the advantage of good stability performance of steel pipe tower members is obvious.

(3) Construct connections

In terms of structural connection, the main materials of the galvanized power transmission steel pipe tower are connected by flanges or intersecting connections, the diagonal materials are connected by plug-in plates or intersecting connections, the main materials of the angle steel tower are connected by internal and external connections, and other members are mainly connected by connecting plates and bolts. The flange and plug plate connection structure of steel pipe towers is relatively simple. Although it increases the welding workload, it reduces the adverse effects of eccentricity of angle steel components on the load-bearing performance of the structure. At the same time, it enhances the stiffness and density of the connection nodes, which helps to improve the overall stiffness and stability of the structure and its ability to resist wind induced dynamic loads.
