Description

Technical Field

[0002] With the rapid development of the power industry, transmission line towers are important facilities for supporting and fixing transmission lines. Their structural design and performance optimization are of great significance to improving the safety and stability of transmission lines. Traditional transmission line towers usually adopt straight or angle steel structures. Although they have certain bearing capacity and stability, their wind resistance and earthquake resistance still need to be improved in complex environments such as extreme weather and natural disasters.

[0003] The existing transmission line tower plays a fixed bearing role for the power lines, and needs to be stably installed in different complex terrain environments. When extreme wind and snow weather occurs, the transmission tower may be relatively insufficient in wind and tensile resistance due to the stability of its own structure. Natural disasters such as low wind and earthquakes have a greater impact on the tower, and the tower body's disaster resistance and tensile resistance are relatively insufficient. The overall stability and bearing capacity of the tower are average. For this reason, we propose an X-curve transmission line tower to solve the above problems. Utility Model Content
