China Angle Steel Transposition Tower Supplier
As the core supplier of high-voltage transmission towers, relying on the strength of national high-tech enterprises and Qingdao's local complete industrial chain, Qingdao Anbang New Energy has been deeply involved in the field of intelligent manufacturing of power steel structures for more than ten years, focusing on the core needs of high-voltage and ultra-high voltage transmission lines, and creating a product matrix of high-quality angle steel transposition towers.
What is an angle steel transposition tower？
The angle steel transposition tower is an exclusive special tower for high-voltage and ultra-high voltage transmission lines, with Q235/Q355 high-strength angle steel as the core main material, assembled into a space truss structure through bolted connection, and the core function is to realize the periodic spatial position exchange of three-phase conductors, in layman's terms, it is to take turns changing seats for three-phase conductors.
Different from ordinary angle steel transmission towers, its structural design pays more attention to the spatial adaptability and force stability of wire transposition, and adds special transposition fittings and wire guide structures, which can accurately adjust the phase position of the wire, so that the three-phase wire occupies different spatial positions on the whole line, so as to balance the electrical parameters such as three-phase inductance, capacitance, and impedance.
As a key special pole tower of high-voltage transmission lines, it not only undertakes the basic functions of wire mounting, load bearing, wind and earthquake resistance, but also effectively protects generators, transformers and other power equipment, prevents relay protection from malfunctioning, reduces inductive interference to surrounding communication lines, and ensures the safety, efficiency and stability of long-distance transmission.
What are the Classifications of Galvanized Angle Steel Transposition Tower?
Qingdao Anbang New Energy angle steel transposition tower has a complete category, combined with the three core dimensions of voltage level, transposition mode and structural type, each series strictly follows the national standard production of the power industry, taking into account the universality and exclusive adaptability, and accurately matches the individual needs of different high-voltage transmission projects:
1. By voltage level
Covering high-pressure angle steel transposition towers (110kV-220kV) and ultra-high pressure angle steel transposition towers (≥330kV).
The high-voltage model is suitable for industrial parks and cross-regional transmission branch lines to meet the needs of conventional long-distance transmission and transposition.
The UHV model is designed with structural reinforcement to optimize truss density and node bearing, and is suitable for long-distance and large-capacity trunk transmission lines of 500kV and above, which can achieve more accurate phase adjustment and ensure the balance of three-phase parameters.
2. Divide by transposition
It is divided into two categories: single-tower transposition type and double-tower transposition type.
The single-tower transposition type adopts a compact design, with a streamlined structure and a small footprint, which is suitable for scenarios with limited line space, and can complete the three-phase conductor transposition on a single tower.
The two-tower transposition type is the recommended scheme for UHV lines of 500kV and above, which realizes wire transposition through the synergy of the two towers, with stronger stability, and is suitable for high-load and long-distance transmission scenarios, and is usually equipped with 1-2 sets of transposition towers every 100km line.
3. Divided by structural type
It is divided into wine glass type angle steel transposition tower, cat head type angle steel transposition tower, and dry type angle steel transposition tower.
The wine glass type is adapted to horizontally arrange the wires, and the transposition operation is convenient, which is the mainstream selection of high-voltage lines.
The cat head type adopts a triangular arrangement of wire design, which has outstanding wind resistance and ice resistance, and is suitable for complex environments such as coastal and alpine environments.
The dry-type structure has large stiffness and strong bearing capacity, and is suitable for heavy loads and large-span transposition scenarios.
