Upper-shaped: Shaped like the Chinese character (up), with triangular conductor arrangements, this type of tower is commonly used for short-distance power transmission in my country, particularly for power lines at voltage levels of 110kV and below.
Cat-head type: Resembling a cat's head, this is a type of high-voltage straight-line transmission tower with isosceles triangular conductor arrangements. Commonly used for long-distance and high-voltage transmission.
Wine glass type: Shaped like a wine glass, this is a close relative of the cat-head tower. With horizontal conductor arrangements, it is commonly used for straight-line towers and load-bearing towers (tension, angle, or terminal towers), and is frequently used for long-distance and high-voltage transmission.
Dry-shaped: Named for its resemblance to the Chinese character (dry), this tower features triangular conductor arrangements and is used as a load-bearing tower. Commonly used for medium- to short-distance transmission at voltage levels of 220kV and above, it boasts a simple structure and good economic efficiency.
Portal type: A tower that uses two columns to support the conductors and overhead ground wires. The conductors are arranged horizontally, like a large "gate" character, and is used as a terminal tower.
