:: >Power towers are generally divided into five types according to their shapes: wine glass type, cat head type, upward type, dry type and barrel type. According to their uses, they are divided into: tension tower and linear tower. , corner towers, transposition towers (to change the conductor phase position), terminal towers and spanning towers, etc. Their structural characteristics are that various tower types are space truss structures, and the rods are mainly composed of single equilateral angle steel or combined angle steel. , materials generally use

Individual components such as tower feet It is made up of several steel plates welded into an assembly, so hot-dip galvanizing is extremely convenient for corrosion protection, transportation and construction and erection.

: >The voltage level is restricted by economic bottlenecks and the current situation of extensive use of concrete, angle iron trusses, self-supporting poles and guyed pole towers. Many external conditions such as urban renewal and environmental protection, lack of land resources, and agricultural mechanization also force the use of concrete poles that are prone to aging due to acid rain, poor surface decoration properties, and angle iron racks that occupy a lot of valuable land resources and hinder the use of agricultural mechanization. Pole towers are being upgraded towards steel self-standing poles that are environmentally friendly, easy to decorate and beautify, occupy less space, have high safety factors, and have high performance-price ratio.
