Electric power transmission towers serve as critical supporting structures within high-voltage transmission systems, utilized to suspend transmission conductors and efficiently and safely convey electrical energy from power stations to distant substations and end-users. Typically constructed from high-strength steel, these towers possess exceptional resistance to wind, seismic activity, and corrosion, thereby ensuring stable operation across a wide range of harsh environmental conditions.

|
Tangent Tower |
Used for straight sections of a transmission line; it bears only vertical and horizontal loads, features a simple structure, and requires minimal steel. |
Continuous straight sections in plains, hills, etc. |
|
Tension Tower |
Designed to withstand conductor tension; utilized at line angles, terminal points, or major spans; while structurally robust, it entails higher construction costs. |
Mountainous regions, riverbanks, and line terminals |
|
Angle Tower |
A specialized tension tower designed to accommodate changes in line direction, requiring the balancing of asymmetrical tensile forces from opposing sides. |
Route turning points |
|
Terminal Tower |
Situated at the starting and ending points of a transmission line; it bears immense unilateral tensile loads and demands the highest level of structural strength. |
Substation entry and exit points |
|
Major Crossing Tower |
Towering over 100 meters in height with spans exceeding 1,000 meters, it is employed for crossing wide bodies of water such as the Yangtze and Yellow Rivers. |
Areas involving major hydraulic or transportation obstacles |
Product Feature And Application
The electric power transmission towers manufactured by our facility are designed for the long-distance transmission of electrical energy. Serving as the "piers" of overhead lines, they support high-voltage conductors as they span mountains, rivers, and urban areas, thereby enabling high-capacity, low-loss power transmission. Through scientific layout and structural design, our transmission towers are widely applicable to transmission lines ranging from 35kV to 1000kV-and even higher voltage levels-making them a critical component of ultra-high-voltage (UHV) transmission projects.
Design Standards
Material Requirements
Primary structural components typically utilize high-strength angle steel or steel tubing (such as grades Q235 and Q345), while connections employ high-strength bolts of Grade 8.8 or higher.
01
Corrosion Protection
A hot-dip galvanizing process is applied, ensuring a zinc coating thickness of ≥86 μm to guarantee a corrosion-resistant service life of over 30 years, even in humid or industrially polluted environments.
02
Wind Resistance
The design wind pressure typically ranges from 0.65 to 1.0 kN/m², corresponding to wind speeds of up to 30–40 m/s (equivalent to a Category 12 typhoon), thereby meeting the requirements for extreme climatic conditions.
03
Seismic Design
The structure is designed to withstand seismic intensities ranging from Grade 6 to 8, ensuring structural integrity and safety in seismically active regions.
04
Safety Clearances
The minimum ground clearance for conductors on 500 kV transmission lines is 14 meters, while for 1000 kV lines, it exceeds 19.5 meters; consequently, the actual height of the transmission towers can reach 70 to 80 meters.
05
FAQ
Q: How tall are power transmission towers?
A: The height of a communication antenna tower varies significantly depending on the voltage level, terrain, and intended use, generally ranging from 20 to 300 meters.
