Power Transmission Tower
A transmission tower or power tower (electricity pylon or electric pylon in the United Kingdom, Canada and parts of Europe) is a tall structure, usually a steel lattice tower, used to support an overhead power line.
They are used in high-voltage AC and DC systems, and come in a wide variety of shapes and sizes. Typical height ranges from 15 to 55 m (49 to 180 ft), though the tallest are the 370 m (1,214 ft) towers of a 2,700 m (8,858 ft) span of Zhoushan Island Overhead Powerline Tie. In addition to steel, other materials may be used, including concrete and wood.
Angle-steel tower, regular quadrangular truss structure communication tower, using Q345B high-quality steel as the main tower body material, rigid structure, small deformation; angle steel splicing connection, light-weight parts, tower can be manually transported and installed at low cost. Maximum 6 layers of platform can be equipped, each platform supports 6 antennas.
