A single tube power tower is mainly composed of a single large-diameter conical steel pipe, and the cross-section of the tower body is commonly circular or regular polygon, presenting a conical appearance with a larger lower part and a smaller upper part. The stable connection between each tower section is achieved through plugs or flanges, and there is an internal ladder for personnel to climb and maintain. At the same time, internal wiring is used to protect the feeder and maintain the balance of the tower body.

· Structural characteristics

· Main structure: The tower is mainly composed of a single large-diameter conical steel pipe, and the cross-section of the tower body is usually circular or regular polygon. The overall shape is conical, with a larger lower part and a smaller upper part, and the design is simple.

· Connection method: The tower sections are connected as a whole through plug-in or flange connection, which is firm and easy to install, and can adapt to installation in various complex sites.

· Internal structure: Equipped with built-in climbing ladder and wiring method, it not only provides a convenient and safe operating environment for operators, but also prevents the feeder from being exposed to sunlight and rain, prolongs its service life, and does not cause the center of gravity of the tower to shift due to the installation of the feeder.。

· Performance advantages

· Small footprint: With a compact structure, it has obvious advantages in occupying land resources compared to traditional angle steel towers. It is suitable for areas with tight land resources such as urban areas, suburban residential communities, universities, commercial districts, scenic spots, and industrial parks.

· Fast construction and installation speed: The installation process is relatively simple and generally requires specialized large-scale installation machinery for lifting. With the assistance of machinery, less manpower is needed, and the operation speed is fast, which can shorten the construction period.

· Strong load capacity: Made of high-quality steel, the steel pipe components have a symmetrical and isotropic cross-section, with materials evenly distributed around the perimeter. The cross-section has high bending stiffness and can withstand large loads.

· Good wind resistance performance: By reasonable design, such as increasing the thickness of steel pipe walls and optimizing support structures, its wind resistance can be improved to ensure stability under adverse weather conditions, and it can generally withstand wind speeds of a certain degree.

· Beautiful appearance: The appearance is simple and atmospheric, with a straight and symmetrical body shape that can blend well with the surrounding environment. Especially in areas with high landscape requirements, it has significant advantages and can reduce the impact on urban landscapes and natural environments.

·Technical parameter

· Material: Steel and alloy structural steel are generally used, such as Q235, Q345, etc. These materials have good strength and toughness, and can meet the requirements of power tower use.

· Specification: The common height range is between 15 meters and 50 meters, and can be customized according to actual needs to meet the requirements of different voltage levels and transmission lines.

· Steel plate thickness: The thickness of the steel plate for the pole body is generally above 5 millimeters, and the thickness of the flange is above 20 millimeters. The specific thickness is determined based on factors such as the height and load of the power tower.

· Compressive and seismic performance: The compressive capacity is generally between 0.35-0.65MPa, and the seismic grade can reach level 8, which can withstand a certain degree of natural disasters.

· Application scenarios

· Urban power grid: In cities, due to the precious land resources, single tube power towers can provide reliable power transmission support in limited space, and their beautiful appearance can coordinate with the urban landscape, reducing the impact on the urban environment.

· Transmission line renovation: For some renovation projects of old transmission lines, single tube power towers can take advantage of their small footprint and fast construction speed to quickly replace or upgrade the towers without affecting the operation of the original lines, improving the performance and reliability of the transmission lines.

· Special areas: In areas with high landscape requirements, such as nature reserves, tourist attractions, etc., single tube power towers can reduce damage to natural landscapes and ecological environments with their simple and beautiful appearance, achieving a balance between power transmission and environmental protection.
