220/230kv Electric Power Transmission Tower
Transmission line towers are usually classified according to shape, including glass type, cat head type, upper type, dry type and bucket type. According to its functions, there are tension transmission line towers, suspension transmission line towers, corner transmission line towers, terminal corner transmission line towers (dead end towers), river crossing towers, etc.
Transmission lattice tower is a steel structure used on transmission and distribution overhead lines. The main purpose of these structures is the transport of the energy from the production plants to the consumption areas.
The design and material types of a lattice tower are linked to the transferred load from cables to the structure and the operation voltage. The line voltage can be from 35kV up to 750kV and the loads are designed taking in consideration the span, angle line, type of cable and climate conditions of the location. There are several tower configurations, but the most common are alignment, angle, reinforcement, and dead end.
A lattice tower is a freestanding framework tower. They can be used as a radio tower (a self-radiating tower or as a carrier for aerials) or as an observation tower. 3 Legged Tubular Steel Tower is a self-supporting high-rise steel structure. Main features: 3 Legged Tubular Steel Tower is made of steel pipe, and the body has a triangular cross section.
Features:
The steel pipe is used as the column material, the wind load coefficient is small, and the wind resistance is strong.
The tower column is connected by an outer flange,
The tower is arranged in a triangular shape to save steel.
The roots are small, the land resources are saved, and the site selection is convenient.
The tower body is light in weight,
Truss structure design, convenient transportation and installation, and short construction period.
The materials and fabrication of our Transmission Structures comply with welding standards and user requirements.
