Key features:

Sturdy Material: The core is made of high-quality galvanized iron and steel plates, formed by professional cutting, rolling and seamless welding. It not only retains the high strength and toughness of iron and steel materials, which can stably bear 33kV power transmission lines and resist outdoor wind and rain erosion; but also adopts integral galvanizing treatment on the surface. The zinc layer is closely combined with the base material with strong compactness, which can effectively isolate moisture, acid and alkali, ultraviolet rays, etc., eliminate rust from the source, and improve equipment durability.

Stable Power Transmission: Developed in strict accordance with 33kV medium and high-voltage power transmission standards, the mechanical structure of the tower body has undergone rigorous calculation. The height, cross-sectional size and bearing capacity are all in line with the transmission needs of 33kV voltage level, which can stably support supporting equipment such as insulators and hardware, and avoid various transmission failures. The overall center of gravity of the tower body is balanced, which can effectively cope with harsh outdoor weather such as strong winds, heavy rains and snowstorms, ensuring the continuity and safety of medium-voltage power transmission.

Strong Scene Adaptability: According to the different engineering needs such as rural power grid upgrading and power transmission in remote areas, the tower height, bottom diameter and bearing capacity can be flexibly customized without additional adjustment of the overall structure, which can accurately adapt to the use scenarios of different terrains and different transmission capacities. A full set of supporting accessories is provided in one stop, including ladders, maintenance platforms, lightning arresters, etc., without separate purchase and assembly, which greatly reduces procurement and construction costs and adapts to the personalized needs of various projects.

Fast Installation Speed: Adopting a lightweight segmented design, each segment of the tower body has a moderate weight, which can be delivered to the construction site by conventional transportation equipment without large transport vehicles, especially suitable for transportation needs in remote and inaccessible areas. Each segment is accurately connected, the on-site assembly process is simple, no complex large-scale construction equipment is needed, the labor input is small, the construction period is short, and the installation can be completed quickly and put into use, effectively controlling the project construction cost.
