The structural characteristics of electric power towers are that various tower types belong to spatial truss structures, and the members are mainly composed of single equilateral angle steel or composite angle steel. The materials generally use Q235 (A3F) and Q345 (16Mn). According to its shape, it is generally divided into five types: wine glass type, cat head type, top type, stem type, and barrel type. Structurally, power iron towers mainly include angle steel towers, steel pipe poles, and steel pipe narrow foundation towers. Angle steel towers are generally used in the wild, while steel pipe poles and narrow base steel pipe towers are generally used in urban areas due to their smaller footprint than angle steel towers.

Power towers are an important component of the power system, also known as transmission line towers, which are equipment used to support overhead lines during high-voltage transmission. Its main functions include:

Supporting function: Power towers can withstand the components and tension of transmission lines, and disperse them on the foundation and ground to ensure the safe and stable operation of transmission lines.

Fixed function: Electric power towers can firmly fix transmission lines on the tower body, avoiding line detachment or disconnection caused by wind, human damage, and other reasons.

Insulation function: Power towers are usually made of insulation materials to ensure the insulation performance of transmission lines, avoid current leakage, and ensure the stability of transmission lines.

Stability function: The height and structure of power towers can withstand the impact of adverse factors such as natural disasters, ensuring the safe operation of transmission lines.
