220kv Steel Transmission Line Tower (NTSTT-014)

Materials are generally Q235(A3F/ST37-2) and Q345(16Mn/ST 52-3 ). Including all accessaries like bolt and nut. Based on application, it can be divided into: Strain tower, straight line tower, angle tower, transposition tower (tower for transposition of wire phase position), terminal tower and crossing tower, etc. Their structural features are: All kinds of towers are of space truss structures; Bard are mainly composed of single equal angle steel or assembling angle steel; Bars are connected by black bolts with shearing force; Entire tower is composed of angle steels, link plates and bolts; A few components like tower base are assemblies of welded steel plates for convenience of hot galvanizing anti-corrosion, For steel towers that with calling height below 60m, shackles are mounted on one of main columns for construction people to climb to work.
This kind of transmission line tower is featured of great loading, long time life and sound stability, widely used in electric power, communication, illumination projects.
