High-voltage AC Transmission Lines Characteristics:
1) High reliability requirements for safe operation. Due to the large transmission capacity of high-voltage AC transmission lines, energy transmission lines, which are often the main power points and load centers, play a very important role in the power grid. Once a safety accident occurs, it will have a great impact on the economy.
2) The structural parameters of the line are high. High-voltage AC transmission lines have high towers, long insulator strings, many insulator pieces, and large tonnage. Not only is it difficult to repair after a collapse accident, but it also requires very high preparation for spare parts.
3) The operating parameters of the line are high. The rated voltage of high-voltage lines is relatively high, making the electric field intensity around charged objects higher.
4) The line is long and the geographical environment along the line is complex. High-voltage lines often pass through mountains and valleys, causing transportation difficulties and heavy maintenance workload.

500kV transmission line towers are uniquely designed to handle the large current loads and high voltages needed for long-distance, heavy power transmission applications. Typically 150 to 250 feet tall to provide ample ground clearance for conductors. Among the tallest towers.
110kV electric towers serve an important role in regional transmission and distribution at moderate voltages and tower heights. Lower than 230kV or 500kV systems. Set in concrete piers or steel grillage foundations anchoring the tower base.
33kV power towers provide medium voltage transmission and distribution that is vital for delivering power locally from the high voltage grid. Used for distribution of power to substations, towns and large facilities from grid.
Tubular transmission steel poles are widely used in high-voltage power transmission networks. Their tubular design provides several advantages, including enhanced structural strength, durability, and adaptability to various transmission line configurations. These towers play a critical role in ensuring the efficient and reliable transmission of electrical energy over long distances.
A transmission line tower is a tower-shaped building used for power transmission. Their structural characteristics are that all tower types are space truss structures. The rods are mainly composed of single equilateral angle steel or combined angle steel. The materials generally use Q235 (A3F) and Q345 (16Mn). The connections between the rods are made of thick steel.
A 4-legged angle steel microwave and antenna tower is a self-supporting lattice structure primarily used for telecommunication, broadcasting, and radar applications. These towers are engineered to support heavy equipment, resist environmental loads (wind, seismic forces), and ensure stable signal transmission over long distances. Their design leverages angle steel components for durability, modularity, and ease of assembly.
