Transmission Line Towers
Customized according to drawings
Transmission line towers are steel structures used to support and suspend conductors and ground wires in overhead transmission lines, ensuring necessary electrical clearances. Their design must strictly adhere to the line's electrical insulation and mechanical load requirements. Major tower types include straight-line towers for linear support, tension towers and corner towers for line anchorage and cornering, terminal towers for line start and end points, transposition towers for phase adjustment on long lines, and spanning towers for special span requirements. The tower's main structure is typically constructed of Q235, Q355, or higher-strength angle steel, connected by gusset plates and high-strength bolts to form a spatial truss system. The tower is hot-dip galvanized for corrosion resistance. Its core function is to safely withstand conductor tension, vertical loads (including deadweight and ice weight), and lateral wind loads under various operating conditions (such as maximum wind speeds, ice cover thickness, and extreme temperatures). It also provides reliable support for the installation of conductors, ground wires, OPGW composite optical cables, insulator strings, and various hardware, thereby ensuring the mechanical strength, stability, and electrical safety and reliability of the transmission line.
