High Voltage Angle Steel Transposition Tower

The Qingdao Anbang New Energy High Voltage Angle Steel Transposition Tower is a core phase-shifting device suitable for 110kV-1000kV ultra-high voltage transmission lines. It features a high-strength angle steel lattice structure and precise phase-shifting design to eliminate line asymmetric currents and correct three-phase voltage deviations.

The tower offers advantages such as high strength, corrosion resistance, seismic resistance, and easy installation, making it widely used in long-distance ultra-high voltage transmission projects to ensure the efficient and stable operation of the power grid.

Core Advantages

High-Strength Structural Design

The main material of the High Voltage Angle Steel Transposition Tower is Q355B and Q420B high-strength angle steel. It uses a lattice bolt-connected structure with excellent mechanical performance, capable of withstanding extreme loads such as strong winds, ice accumulation, and earthquakes, with structural stability far exceeding industry standards.

Ultra-Long Corrosion Resistance

The tower adopts a dual corrosion protection process of hot-dip galvanization and epoxy powder coating, providing a corrosion protection period of ≥30 years.

It is suitable for complex outdoor environments such as coastal areas, mountains, and saline-alkali land, significantly reducing subsequent maintenance costs.

Precise Phase-Shifting Performance

The phase-shifting accuracy of the high voltage angle steel tower reaches ±2°, efficiently eliminating asymmetric currents in long-distance transmission lines, correcting three-phase voltage deviations, improving transmission efficiency, and reducing line losses.

Factory Prefabrication and Standardization

The high voltage angle steel phase-shifting tower is fully prefabricated in the factory, with component precision controlled within ±0.5mm. Bolt connections are used on-site for easy installation, significantly shortening construction cycles.

High Seismic Protection Level

The seismic resistance level reaches 7-8, meeting GB 50260 standards, with protection levels from IP23 to IP54. It is suitable for both outdoor and indoor scenarios, ensuring the safe operation of the power grid.

Product Working Principle

The High Voltage Angle Steel Transposition Tower is a key phase-changing device for ultra-high voltage transmission lines. Its core working principles are:

Three-phase Conductor Swapping

The high voltage angle steel phase-shifting tower uses a specially designed crossarm and insulator arrangement at the tower head to achieve the spatial position exchange of three-phase conductors in a transmission line, breaking line asymmetry and eliminating zero-sequence and negative-sequence currents caused by asymmetric conductor arrangements.

Voltage Deviation Correction

By precisely controlling the phase-shifting angle and swapping distance, it corrects the phase deviation of three-phase voltage during long-distance transmission, ensuring balanced three-phase voltage and improving the power factor and transmission stability of the power grid.

Load Balanced Transmission

The lattice angle steel structure of the high voltage angle steel phase-shifting tower evenly transfers conductor tension, wind load, ice load, and other forces to the foundation, preventing local stress concentration and ensuring the long-term safe operation of the tower and lines.

Electromagnetic Optimization

It optimizes the electromagnetic environment of the line, reduces electromagnetic interference, lowers the impact on surrounding communication and electronic devices, and meets the environmental protection and safety requirements of the power grid.
